# Google APIs Client Library for PHP #
\n"; } ``` ### Authentication with OAuth ### > An example of this can be seen in [`examples/simple-file-upload.php`](examples/simple-file-upload.php). 1. Follow the instructions to [Create Web Application Credentials](docs/oauth-web.md#create-authorization-credentials) 1. Download the JSON credentials 1. Set the path to these credentials using `Google\Client::setAuthConfig`: ```php $client = new Google\Client(); $client->setAuthConfig('/path/to/client_credentials.json'); ``` 1. Set the scopes required for the API you are going to call ```php $client->addScope(Google\Service\Drive::DRIVE); ``` 1. Set your application's redirect URI ```php // Your redirect URI can be any registered URI, but in this example // we redirect back to this same page $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']; $client->setRedirectUri($redirect_uri); ``` 1. In the script handling the redirect URI, exchange the authorization code for an access token: ```php if (isset($_GET['code'])) { $token = $client->fetchAccessTokenWithAuthCode($_GET['code']); } ``` ### Authentication with Service Accounts ### > An example of this can be seen in [`examples/service-account.php`](examples/service-account.php). Some APIs (such as the [YouTube Data API](https://developers.google.com/youtube/v3/)) do not support service accounts. Check with the specific API documentation if API calls return unexpected 401 or 403 errors. 1. Follow the instructions to [Create a Service Account](docs/oauth-server.md#creating-a-service-account) 1. Download the JSON credentials 1. Set the path to these credentials using the `GOOGLE_APPLICATION_CREDENTIALS` environment variable: ```php putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account.json'); ``` 1. Tell the Google client to use your service account credentials to authenticate: ```php $client = new Google\Client(); $client->useApplicationDefaultCredentials(); ``` 1. Set the scopes required for the API you are going to call ```php $client->addScope(Google\Service\Drive::DRIVE); ``` 1. If you have delegated domain-wide access to the service account and you want to impersonate a user account, specify the email address of the user account using the method setSubject: ```php $client->setSubject($user_to_impersonate); ``` #### How to use a specific JSON key If you want to a specific JSON key instead of using `GOOGLE_APPLICATION_CREDENTIALS` environment variable, you can do this: ```php $jsonKey = [ 'type' => 'service_account', // ... ]; $client = new Google\Client(); $client->setAuthConfig($jsonKey); ``` ### Making Requests ### The classes used to call the API in [google-api-php-client-services](https://github.com/googleapis/google-api-php-client-services) are autogenerated. They map directly to the JSON requests and responses found in the [APIs Explorer](https://developers.google.com/apis-explorer/#p/). A JSON request to the [Datastore API](https://developers.google.com/apis-explorer/#p/datastore/v1beta3/datastore.projects.runQuery) would look like this: ```json POST https://datastore.googleapis.com/v1beta3/projects/YOUR_PROJECT_ID:runQuery?key=YOUR_API_KEY { "query": { "kind": [{ "name": "Book" }], "order": [{ "property": { "name": "title" }, "direction": "descending" }], "limit": 10 } } ``` Using this library, the same call would look something like this: ```php // create the datastore service class $datastore = new Google\Service\Datastore($client); // build the query - this maps directly to the JSON $query = new Google\Service\Datastore\Query([ 'kind' => [ [ 'name' => 'Book', ], ], 'order' => [ 'property' => [ 'name' => 'title', ], 'direction' => 'descending', ], 'limit' => 10, ]); // build the request and response $request = new Google\Service\Datastore\RunQueryRequest(['query' => $query]); $response = $datastore->projects->runQuery('YOUR_DATASET_ID', $request); ``` However, as each property of the JSON API has a corresponding generated class, the above code could also be written like this: ```php // create the datastore service class $datastore = new Google\Service\Datastore($client); // build the query $request = new Google\Service\Datastore_RunQueryRequest(); $query = new Google\Service\Datastore\Query(); // - set the order $order = new Google\Service\Datastore_PropertyOrder(); $order->setDirection('descending'); $property = new Google\Service\Datastore\PropertyReference(); $property->setName('title'); $order->setProperty($property); $query->setOrder([$order]); // - set the kinds $kind = new Google\Service\Datastore\KindExpression(); $kind->setName('Book'); $query->setKinds([$kind]); // - set the limit $query->setLimit(10); // add the query to the request and make the request $request->setQuery($query); $response = $datastore->projects->runQuery('YOUR_DATASET_ID', $request); ``` The method used is a matter of preference, but *it will be very difficult to use this library without first understanding the JSON syntax for the API*, so it is recommended to look at the [APIs Explorer](https://developers.google.com/apis-explorer/#p/) before using any of the services here. ### Making HTTP Requests Directly ### If Google Authentication is desired for external applications, or a Google API is not available yet in this library, HTTP requests can be made directly. If you are installing this client only to authenticate your own HTTP client requests, you should use [`google/auth`](https://github.com/googleapis/google-auth-library-php#call-the-apis) instead. The `authorize` method returns an authorized [Guzzle Client](http://docs.guzzlephp.org/), so any request made using the client will contain the corresponding authorization. ```php // create the Google client $client = new Google\Client(); /** * Set your method for authentication. Depending on the API, This could be * directly with an access token, API key, or (recommended) using * Application Default Credentials. */ $client->useApplicationDefaultCredentials(); $client->addScope(Google\Service\Plus::PLUS_ME); // returns a Guzzle HTTP Client $httpClient = $client->authorize(); // make an HTTP request $response = $httpClient->get('https://www.googleapis.com/plus/v1/people/me'); ``` ### Caching ### It is recommended to use another caching library to improve performance. This can be done by passing a [PSR-6](https://www.php-fig.org/psr/psr-6/) compatible library to the client: ```php use League\Flysystem\Adapter\Local; use League\Flysystem\Filesystem; use Cache\Adapter\Filesystem\FilesystemCachePool; $filesystemAdapter = new Local(__DIR__.'/'); $filesystem = new Filesystem($filesystemAdapter); $cache = new FilesystemCachePool($filesystem); $client->setCache($cache); ``` In this example we use [PHP Cache](http://www.php-cache.com/). Add this to your project with composer: ``` composer require cache/filesystem-adapter ``` ### Updating Tokens ### When using [Refresh Tokens](https://developers.google.com/identity/protocols/OAuth2InstalledApp#offline) or [Service Account Credentials](https://developers.google.com/identity/protocols/OAuth2ServiceAccount#overview), it may be useful to perform some action when a new access token is granted. To do this, pass a callable to the `setTokenCallback` method on the client: ```php $logger = new Monolog\Logger(); $tokenCallback = function ($cacheKey, $accessToken) use ($logger) { $logger->debug(sprintf('new access token received at cache key %s', $cacheKey)); }; $client->setTokenCallback($tokenCallback); ``` ### Debugging Your HTTP Request using Charles ### It is often very useful to debug your API calls by viewing the raw HTTP request. This library supports the use of [Charles Web Proxy](https://www.charlesproxy.com/documentation/getting-started/). Download and run Charles, and then capture all HTTP traffic through Charles with the following code: ```php // FOR DEBUGGING ONLY $httpClient = new GuzzleHttp\Client([ 'proxy' => 'localhost:8888', // by default, Charles runs on localhost port 8888 'verify' => false, // otherwise HTTPS requests will fail. ]); $client = new Google\Client(); $client->setHttpClient($httpClient); ``` Now all calls made by this library will appear in the Charles UI. One additional step is required in Charles to view SSL requests. Go to **Charles > Proxy > SSL Proxying Settings** and add the domain you'd like captured. In the case of the Google APIs, this is usually `*.googleapis.com`. ### Controlling HTTP Client Configuration Directly Google API Client uses [Guzzle](http://docs.guzzlephp.org/) as its default HTTP client. That means that you can control your HTTP requests in the same manner you would for any application using Guzzle. Let's say, for instance, we wished to apply a referrer to each request. ```php use GuzzleHttp\Client; $httpClient = new Client([ 'headers' => [ 'referer' => 'mysite.com' ] ]); $client = new Google\Client(); $client->setHttpClient($httpClient); ``` Other Guzzle features such as [Handlers and Middleware](http://docs.guzzlephp.org/en/stable/handlers-and-middleware.html) offer even more control. ### Service Specific Examples ### YouTube: https://github.com/youtube/api-samples/tree/master/php ## How Do I Contribute? ## Please see the [contributing](.github/CONTRIBUTING.md) page for more information. In particular, we love pull requests - but please make sure to sign the contributor license agreement. ## Frequently Asked Questions ## ### What do I do if something isn't working? ### For support with the library the best place to ask is via the google-api-php-client tag on StackOverflow: https://stackoverflow.com/questions/tagged/google-api-php-client If there is a specific bug with the library, please [file an issue](https://github.com/googleapis/google-api-php-client/issues) in the GitHub issues tracker, including an example of the failing code and any specific errors retrieved. Feature requests can also be filed, as long as they are core library requests, and not-API specific: for those, refer to the documentation for the individual APIs for the best place to file requests. Please try to provide a clear statement of the problem that the feature would address. ### I want an example of X! ### If X is a feature of the library, file away! If X is an example of using a specific service, the best place to go is to the teams for those specific APIs - our preference is to link to their examples rather than add them to the library, as they can then pin to specific versions of the library. If you have any examples for other APIs, let us know and we will happily add a link to the README above! ### Why do some Google\Service classes have weird names? ### The _Google\Service_ classes are generally automatically generated from the API discovery documents: https://developers.google.com/discovery/. Sometimes new features are added to APIs with unusual names, which can cause some unexpected or non-standard style naming in the PHP classes. ### How do I deal with non-JSON response types? ### Some services return XML or similar by default, rather than JSON, which is what the library supports. You can request a JSON response by adding an 'alt' argument to optional params that is normally the last argument to a method call: ```php $opt_params = array( 'alt' => "json" ); ``` ### How do I set a field to null? ### The library strips out nulls from the objects sent to the Google APIs as its the default value of all of the uninitialized properties. To work around this, set the field you want to null to `Google\Model::NULL_VALUE`. This is a placeholder that will be replaced with a true null when sent over the wire. ## Code Quality ## Run the PHPUnit tests with PHPUnit. You can configure an API key and token in BaseTest.php to run all calls, but this will require some setup on the Google Developer Console. phpunit tests/ ### Coding Style To check for coding style violations, run ``` vendor/bin/phpcs src --standard=style/ruleset.xml -np ``` To automatically fix (fixable) coding style violations, run ``` vendor/bin/phpcbf src --standard=style/ruleset.xml ``` includes/google-api-8/SECURITY.md 0000644 00000000511 15021152110 0012314 0 ustar 00 # Security Policy To report a security issue, please use [g.co/vulnz](https://g.co/vulnz).

=======
This repository holds all interfaces/classes/traits related to
[PSR-3](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md).
Note that this is not a logger of its own. It is merely an interface that
describes a logger. See the specification for more details.
Installation
------------
```bash
composer require psr/log
```
Usage
-----
If you need a logger, you can use the interface like this:
```php
logger = $logger;
}
public function doSomething()
{
if ($this->logger) {
$this->logger->info('Doing work');
}
try {
$this->doSomethingElse();
} catch (Exception $exception) {
$this->logger->error('Oh no!', array('exception' => $exception));
}
// do something useful
}
}
```
You can then pick one of the implementations of the interface to get a logger.
If you want to implement the interface, you can require this package and
implement `Psr\Log\LoggerInterface` in your code. Please read the
[specification text](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md)
for details.

=============================
A generic function and convention to trigger deprecation notices.
This package provides a single global function named `trigger_deprecation()` that triggers silenced deprecation notices.
By using a custom PHP error handler such as the one provided by the Symfony ErrorHandler component,
the triggered deprecations can be caught and logged for later discovery, both on dev and prod environments.
The function requires at least 3 arguments:
- the name of the Composer package that is triggering the deprecation
- the version of the package that introduced the deprecation
- the message of the deprecation
- more arguments can be provided: they will be inserted in the message using `printf()` formatting
Example:
```php
trigger_deprecation('symfony/blockchain', '8.9', 'Using "%s" is deprecated, use "%s" instead.', 'bitcoin', 'fabcoin');
```
This will generate the following message:
`Since symfony/blockchain 8.9: Using "bitcoin" is deprecated, use "fabcoin" instead.`

with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate

wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

Based on the [constant-time base64 implementation made by Steve "Sc00bz" Thomas](https://github.com/Sc00bz/ConstTimeEncoding),
this library aims to offer character encoding functions that do not leak
information about what you are encoding/decoding via processor cache
misses. Further reading on [cache-timing attacks](http://blog.ircmaxell.com/2014/11/its-all-about-time.html).
Our fork offers the following enchancements:
* `mbstring.func_overload` resistance
* Unit tests
* Composer- and Packagist-ready
* Base16 encoding
* Base32 encoding
* Uses `pack()` and `unpack()` instead of `chr()` and `ord()`
## PHP Version Requirements
Version 2 of this library should work on **PHP 7** or newer. For PHP 5
support, see [the v1.x branch](https://github.com/paragonie/constant_time_encoding/tree/v1.x).
If you are adding this as a dependency to a project intended to work on both PHP 5 and PHP 7, please set the required version to `^1|^2` instead of just `^1` or `^2`.
## How to Install
```sh
composer require paragonie/constant_time_encoding
```
## How to Use
```php
use \ParagonIE\ConstantTime\Encoding;
// possibly (if applicable):
// require 'vendor/autoload.php';
$data = random_bytes(32);
echo Encoding::base64Encode($data), "\n";
echo Encoding::base32EncodeUpper($data), "\n";
echo Encoding::base32Encode($data), "\n";
echo Encoding::hexEncode($data), "\n";
echo Encoding::hexEncodeUpper($data), "\n";
```
Example output:
```
1VilPkeVqirlPifk5scbzcTTbMT2clp+Zkyv9VFFasE=
2VMKKPSHSWVCVZJ6E7SONRY3ZXCNG3GE6ZZFU7TGJSX7KUKFNLAQ====

D558A53E4795AA2AE53E27E4E6C71BDCC4D36CC4F6725A7E664CAFF551456AC1
```
If you only need a particular variant, you can just reference the
required class like so:
```php
use \ParagonIE\ConstantTime\Base64;
use \ParagonIE\ConstantTime\Base32;
$data = random_bytes(32);
echo Base64::encode($data), "\n";
echo Base32::encode($data), "\n";
```
Example output:
```

2vmkkpshswvcvzj6e7sonry3zxcng3ge6zzfu7tgjsx7kukfnlaq====
```

PHP-JWT
=======
A simple library to encode and decode JSON Web Tokens (JWT) in PHP, conforming to [RFC 7519](https://tools.ietf.org/html/rfc7519).
Installation
------------
Use composer to manage your dependencies and download PHP-JWT:
```bash
composer require firebase/php-jwt
```
Optionally, install the `paragonie/sodium_compat` package from composer if your
php is < 7.2 or does not have libsodium installed:
```bash
composer require paragonie/sodium_compat
```
Example
-------
```php
use Firebase\JWT\JWT;
use Firebase\JWT\Key;
$key = "example_key";
$payload = array(
"iss" => "http://example.org",
"aud" => "http://example.com",
"iat" => 1356999524,
"nbf" => 1357000000
);
/**
* IMPORTANT:
* You must specify supported algorithms for your application. See
* https://tools.ietf.org/html/draft-ietf-jose-json-web-algorithms-40
* for a list of spec-compliant algorithms.
*/
$jwt = JWT::encode($payload, $key, 'HS256');
$decoded = JWT::decode($jwt, new Key($key, 'HS256'));
print_r($decoded);
/*
NOTE: This will now be an object instead of an associative array. To get
an associative array, you will need to cast it as such:
*/
$decoded_array = (array) $decoded;
/**
* You can add a leeway to account for when there is a clock skew times between
* the signing and verifying servers. It is recommended that this leeway should
* not be bigger than a few minutes.
*
* Source: http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#nbfDef
*/
JWT::$leeway = 60; // $leeway in seconds
$decoded = JWT::decode($jwt, new Key($key, 'HS256'));
```
Example with RS256 (openssl)
----------------------------
```php
use Firebase\JWT\JWT;
use Firebase\JWT\Key;
$privateKey = << "example.org",
"aud" => "example.com",
"iat" => 1356999524,
"nbf" => 1357000000
);
$jwt = JWT::encode($payload, $privateKey, 'RS256');
echo "Encode:\n" . print_r($jwt, true) . "\n";
$decoded = JWT::decode($jwt, new Key($publicKey, 'RS256'));
/*
NOTE: This will now be an object instead of an associative array. To get
an associative array, you will need to cast it as such:
*/
$decoded_array = (array) $decoded;
echo "Decode:\n" . print_r($decoded_array, true) . "\n";
```
Example with a passphrase
-------------------------
```php
use Firebase\JWT\JWT;
use Firebase\JWT\Key;
// Your passphrase
$passphrase = '[YOUR_PASSPHRASE]';
// Your private key file with passphrase
// Can be generated with "ssh-keygen -t rsa -m pem"
$privateKeyFile = '/path/to/key-with-passphrase.pem';
// Create a private key of type "resource"
$privateKey = openssl_pkey_get_private(
file_get_contents($privateKeyFile),
$passphrase
);
$payload = array(
"iss" => "example.org",
"aud" => "example.com",
"iat" => 1356999524,
"nbf" => 1357000000
);
$jwt = JWT::encode($payload, $privateKey, 'RS256');
echo "Encode:\n" . print_r($jwt, true) . "\n";
// Get public key from the private key, or pull from from a file.
$publicKey = openssl_pkey_get_details($privateKey)['key'];
$decoded = JWT::decode($jwt, new Key($publicKey, 'RS256'));
echo "Decode:\n" . print_r((array) $decoded, true) . "\n";
```
Example with EdDSA (libsodium and Ed25519 signature)
----------------------------
```php
use Firebase\JWT\JWT;
use Firebase\JWT\Key;
// Public and private keys are expected to be Base64 encoded. The last
// non-empty line is used so that keys can be generated with
// sodium_crypto_sign_keypair(). The secret keys generated by other tools may
// need to be adjusted to match the input expected by libsodium.
$keyPair = sodium_crypto_sign_keypair();
$privateKey = base64_encode(sodium_crypto_sign_secretkey($keyPair));
$publicKey = base64_encode(sodium_crypto_sign_publickey($keyPair));
$payload = array(
"iss" => "example.org",
"aud" => "example.com",
"iat" => 1356999524,
"nbf" => 1357000000
);
$jwt = JWT::encode($payload, $privateKey, 'EdDSA');
echo "Encode:\n" . print_r($jwt, true) . "\n";
$decoded = JWT::decode($jwt, new Key($publicKey, 'EdDSA'));
echo "Decode:\n" . print_r((array) $decoded, true) . "\n";
````
Using JWKs
----------
```php
use Firebase\JWT\JWK;
use Firebase\JWT\JWT;
// Set of keys. The "keys" key is required. For example, the JSON response to
// this endpoint: https://www.gstatic.com/iap/verify/public_key-jwk
$jwks = ['keys' => []];
// JWK::parseKeySet($jwks) returns an associative array of **kid** to private
// key. Pass this as the second parameter to JWT::decode.
// NOTE: The deprecated $supportedAlgorithm must be supplied when parsing from JWK.
JWT::decode($payload, JWK::parseKeySet($jwks), $supportedAlgorithm);
```

Tests
-----
Run the tests using phpunit:
```bash
$ pear install PHPUnit
$ phpunit --configuration phpunit.xml.dist
PHPUnit 3.7.10 by Sebastian Bergmann.
.....
Time: 0 seconds, Memory: 2.50Mb
OK (5 tests, 5 assertions)
```
New Lines in private keys
-----
If your private key contains `\n` characters, be sure to wrap it in double quotes `""`
and not single quotes `''` in order to properly interpret the escaped characters.

/* in theory this should be faster than regular modular reductions save for one small issue.
to convert to / from base-2**8 with BCMath you have to call bcmul() and bcdiv() a lot.
to convert to / from base-2**8 with PHP64 you have to call base256_rshift() a lot.
in short, converting to / from base-2**8 is pretty expensive and that expense is
enough to offset whatever else might be gained by a simplified reduction algorithm.
now, if PHP supported unsigned integers things might be different. no bit-shifting
would be required for the PHP engine and it'd be a lot faster. but as is, BigInteger
uses base-2**31 or base-2**26 depending on whether or not the system is has a 32-bit
or a 64-bit OS.

"outside the scope" of PKCS#1. PKCS#1 then refers you to PKCS#12 and PKCS#15 if you're wanting to

two new "fields" to the key - DEK-Info and Proc-Type. These fields are discussed here:

DES-EDE3-CBC as an algorithm, however, is not discussed anywhere, near as I can tell.
DES-CBC and DES-EDE are discussed in RFC1423, however, DES-EDE3-CBC isn't, nor is its key derivation
function. As is, the definitive authority on this encoding scheme isn't the IETF but rather OpenSSL's
own implementation. ie. the implementation *is* the standard and any bugs that may exist in that
implementation are part of the standard, as well.

OpenSSH private keys use a customized version of bcrypt. specifically, instead of encrypting
OrpheanBeholderScryDoubt 64 times OpenSSH's bcrypt variant encrypts
OxychromaticBlowfishSwatDynamite 64 times. so we can't use crypt().
bcrypt is basically Blowfish with an altered key expansion. whereas Blowfish just runs the
key through the key expansion bcrypt interleaves the key expansion with the salt and
password. this renders openssl / mcrypt unusuable. this forces us to use a pure-PHP implementation
of bcrypt. the problem with that is that pure-PHP is too slow to be practically useful.
in addition to encrypting a different string 64 times the OpenSSH implementation also performs bcrypt
from scratch $rounds times. calling crypt() 64x with bcrypt takes 0.7s. PHP is going to be naturally
slower. pure-PHP is 215x slower than OpenSSL for AES and pure-PHP is 43x slower for bcrypt.
43 * 0.7 = 30s. no one wants to wait 30s to load a private key.
another way to think about this.. according to wikipedia's article on Blowfish,
"Each new key requires pre-processing equivalent to encrypting about 4 kilobytes of text".
key expansion is done (9+64*2)*160 times. multiply that by 4 and it turns out that Blowfish,
OpenSSH style, is the equivalent of encrypting ~80mb of text.
more supporting evidence: sodium_compat does not implement Argon2 (another password hashing
algorithm) because "It's not feasible to polyfill scrypt or Argon2 into PHP and get reasonable
performance. Users would feel motivated to select parameters that downgrade security to avoid
denial of service (DoS) attacks. The only winning move is not to play"

*
* Whereas BigInteger.php's 32-bit engine works on PHP 64-bit this 32-bit implementation
* of SHA3 will *not* work on PHP 64-bit. This is because this implementation
* employees bitwise NOTs and bitwise left shifts. And the round constants only work
* on 32-bit PHP. eg. dechex(-2147483648) returns 80000000 on 32-bit PHP and
* FFFFFFFF80000000 on 64-bit PHP. Sure, we could do bitwise ANDs but that would slow
* things down.
*
* SHA512 requires BigInteger to simulate 64-bit unsigned integers because SHA2 employees
* addition whereas SHA3 just employees bitwise operators. PHP64 only supports signed
* 64-bit integers, which complicates addition, whereas that limitation isn't an issue
* for SHA3.

* In https://ws680.nist.gov/publication/get_pdf.cfm?pub_id=919061#page=16 KECCAK[C] is

// solely on parameters a potential attacker sends but (1) not everything in $_SERVER is controlled
// by the user and (2) this isn't just looking at the data sent by the current user - it's based
// on the data sent by all users. one user requests the page and a hash of their info is saved.
// another user visits the page and the serialization of their data is utilized along with the

A Note on SFTPv4/5/6 support:
states the following:
"If the client wishes to interoperate with servers that support noncontiguous version
numbers it SHOULD send '3'"
Given that the server only sends its version number after the client has already done so, the above
seems to be suggesting that v3 should be the default version. This makes sense given that v3 is the
most popular.
states the following;
"If the server did not send the "versions" extension, or the version-from-list was not included, the
server MAY send a status response describing the failure, but MUST then close the channel without
processing any further requests."
So what do you do if you have a client whose initial SSH_FXP_INIT packet says it implements v3 and
a server whose initial SSH_FXP_VERSION reply says it implements v4 and only v4? If it only implements
v4, the "versions" extension is likely not going to have been sent so version re-negotiation as discussed
in draft-ietf-secsh-filexfer-13 would be quite impossible. As such, what \phpseclib3\Net\SFTP would do is close the
channel and reopen it with a new and updated SSH_FXP_INIT packet.

/**
* Uploads a file to the SFTP server.
*
* By default, \phpseclib3\Net\SFTP::put() does not read from the local filesystem. $data is dumped directly into $remote_file.
* So, for example, if you set $data to 'filename.ext' and then do \phpseclib3\Net\SFTP::get(), you will get a file, twelve bytes
* long, containing 'filename.ext' as its contents.
*
* Setting $mode to self::SOURCE_LOCAL_FILE will change the above behavior. With self::SOURCE_LOCAL_FILE, $remote_file will
* contain as many bytes as filename.ext does on your local filesystem. If your filename.ext is 1MB then that is how
* large $remote_file will be, as well.
*
* Setting $mode to self::SOURCE_CALLBACK will use $data as callback function, which gets only one parameter -- number
* of bytes to return, and returns a string if there is some data or null if there is no more data
*
* If $data is a resource then it'll be used as a resource instead.
*
* Currently, only binary mode is supported. As such, if the line endings need to be adjusted, you will need to take
* care of that, yourself.
*
* $mode can take an additional two parameters - self::RESUME and self::RESUME_START. These are bitwise AND'd with
* $mode. So if you want to resume upload of a 300mb file on the local file system you'd set $mode to the following:
*
* self::SOURCE_LOCAL_FILE | self::RESUME
*
* If you wanted to simply append the full contents of a local file to the full contents of a remote file you'd replace
* self::RESUME with self::RESUME_START.
*
* If $mode & (self::RESUME | self::RESUME_START) then self::RESUME_START will be assumed.
*
* $start and $local_start give you more fine grained control over this process and take precident over self::RESUME
* when they're non-negative. ie. $start could let you write at the end of a file (like self::RESUME) or in the middle
* of one. $local_start could let you start your reading from the end of a file (like self::RESUME_START) or in the
* middle of one.
*
* Setting $local_start to > 0 or $mode | self::RESUME_START doesn't do anything unless $mode | self::SOURCE_LOCAL_FILE.
*

*
* Employs "folding", as described at
* {@link http://www.cosic.esat.kuleuven.be/publications/thesis-149.pdf#page=66 thesis-149.pdf#page=66}. To quote from
* it, "the idea [behind folding] is to find a value x' such that x (mod m) = x' (mod m), with x' being smaller than x."
*
* Unfortunately, the "Barrett Reduction with Folding" algorithm described in thesis-149.pdf is not, as written, all that
* usable on account of (1) its not using reasonable radix points as discussed in
* {@link http://math.libtomcrypt.com/files/tommath.pdf#page=162 MPM 6.2.2} and (2) the fact that, even with reasonable
* radix points, it only works when there are an even number of digits in the denominator. The reason for (2) is that
* (x >> 1) + (x >> 1) != x / 2 + x / 2. If x is even, they're the same, but if x is odd, they're not. See the in-line
* comments for details.

/**
* Performs modular exponentiation.
*
* The most naive approach to modular exponentiation has very unreasonable requirements, and
* and although the approach involving repeated squaring does vastly better, it, too, is impractical
* for our purposes. The reason being that division - by far the most complicated and time-consuming
* of the basic operations (eg. +,-,*,/) - occurs multiple times within it.
*
* Modular reductions resolve this issue. Although an individual modular reduction takes more time
* then an individual division, when performed in succession (with the same modulo), they're a lot faster.
*
* The two most commonly used modular reductions are Barrett and Montgomery reduction. Montgomery reduction,
* although faster, only works when the gcd of the modulo and of the base being used is 1. In RSA, when the
* base is a power of two, the modulo - a product of two primes - is always going to have a gcd of 1 (because
* the product of two odd numbers is odd), but what about when RSA isn't used?
*
* In contrast, Barrett reduction has no such constraint. As such, some bigint implementations perform a
* Barrett reduction after every operation in the modpow function. Others perform Barrett reductions when the
* modulo is even and Montgomery reductions when the modulo is odd. BigInteger.java's modPow method, however,
* uses a trick involving the Chinese Remainder Theorem to factor the even modulo into two numbers - one odd and
* the other, a power of two - and recombine them, later. This is the method that this modPow function uses.
* {@link http://islab.oregonstate.edu/papers/j34monex.pdf Montgomery Reduction with Even Modulus} elaborates.

*
* Unfortunately, the "Barrett Reduction with Folding" algorithm described in thesis-149.pdf is not, as written, all that
* usable on account of (1) its not using reasonable radix points as discussed in
* {@link http://math.libtomcrypt.com/files/tommath.pdf#page=162 MPM 6.2.2} and (2) the fact that, even with reasonable
* radix points, it only works when there are an even number of digits in the denominator. The reason for (2) is that
* (x >> 1) + (x >> 1) != x / 2 + x / 2. If x is even, they're the same, but if x is odd, they're not. See the in-line

\n"; } ``` ### Authentication with OAuth ### > An example of this can be seen in [`examples/simple-file-upload.php`](examples/simple-file-upload.php). 1. Follow the instructions to [Create Web Application Credentials](docs/oauth-web.md#create-authorization-credentials) 1. Download the JSON credentials 1. Set the path to these credentials using `Google\Client::setAuthConfig`: ```php $client = new Google\Client(); $client->setAuthConfig('/path/to/client_credentials.json'); ``` 1. Set the scopes required for the API you are going to call ```php $client->addScope(Google\Service\Drive::DRIVE); ``` 1. Set your application's redirect URI ```php // Your redirect URI can be any registered URI, but in this example // we redirect back to this same page $redirect_uri = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']; $client->setRedirectUri($redirect_uri); ``` 1. In the script handling the redirect URI, exchange the authorization code for an access token: ```php if (isset($_GET['code'])) { $token = $client->fetchAccessTokenWithAuthCode($_GET['code']); } ``` ### Authentication with Service Accounts ### > An example of this can be seen in [`examples/service-account.php`](examples/service-account.php). Some APIs (such as the [YouTube Data API](https://developers.google.com/youtube/v3/)) do not support service accounts. Check with the specific API documentation if API calls return unexpected 401 or 403 errors. 1. Follow the instructions to [Create a Service Account](docs/oauth-server.md#creating-a-service-account) 1. Download the JSON credentials 1. Set the path to these credentials using the `GOOGLE_APPLICATION_CREDENTIALS` environment variable: ```php putenv('GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account.json'); ``` 1. Tell the Google client to use your service account credentials to authenticate: ```php $client = new Google\Client(); $client->useApplicationDefaultCredentials(); ``` 1. Set the scopes required for the API you are going to call ```php $client->addScope(Google\Service\Drive::DRIVE); ``` 1. If you have delegated domain-wide access to the service account and you want to impersonate a user account, specify the email address of the user account using the method setSubject: ```php $client->setSubject($user_to_impersonate); ``` #### How to use a specific JSON key If you want to a specific JSON key instead of using `GOOGLE_APPLICATION_CREDENTIALS` environment variable, you can do this: ```php $jsonKey = [ 'type' => 'service_account', // ... ]; $client = new Google\Client(); $client->setAuthConfig($jsonKey); ``` ### Making Requests ### The classes used to call the API in [google-api-php-client-services](https://github.com/googleapis/google-api-php-client-services) are autogenerated. They map directly to the JSON requests and responses found in the [APIs Explorer](https://developers.google.com/apis-explorer/#p/). A JSON request to the [Datastore API](https://developers.google.com/apis-explorer/#p/datastore/v1beta3/datastore.projects.runQuery) would look like this: ```json POST https://datastore.googleapis.com/v1beta3/projects/YOUR_PROJECT_ID:runQuery?key=YOUR_API_KEY { "query": { "kind": [{ "name": "Book" }], "order": [{ "property": { "name": "title" }, "direction": "descending" }], "limit": 10 } } ``` Using this library, the same call would look something like this: ```php // create the datastore service class $datastore = new Google\Service\Datastore($client); // build the query - this maps directly to the JSON $query = new Google\Service\Datastore\Query([ 'kind' => [ [ 'name' => 'Book', ], ], 'order' => [ 'property' => [ 'name' => 'title', ], 'direction' => 'descending', ], 'limit' => 10, ]); // build the request and response $request = new Google\Service\Datastore\RunQueryRequest(['query' => $query]); $response = $datastore->projects->runQuery('YOUR_DATASET_ID', $request); ``` However, as each property of the JSON API has a corresponding generated class, the above code could also be written like this: ```php // create the datastore service class $datastore = new Google\Service\Datastore($client); // build the query $request = new Google\Service\Datastore_RunQueryRequest(); $query = new Google\Service\Datastore\Query(); // - set the order $order = new Google\Service\Datastore_PropertyOrder(); $order->setDirection('descending'); $property = new Google\Service\Datastore\PropertyReference(); $property->setName('title'); $order->setProperty($property); $query->setOrder([$order]); // - set the kinds $kind = new Google\Service\Datastore\KindExpression(); $kind->setName('Book'); $query->setKinds([$kind]); // - set the limit $query->setLimit(10); // add the query to the request and make the request $request->setQuery($query); $response = $datastore->projects->runQuery('YOUR_DATASET_ID', $request); ``` The method used is a matter of preference, but *it will be very difficult to use this library without first understanding the JSON syntax for the API*, so it is recommended to look at the [APIs Explorer](https://developers.google.com/apis-explorer/#p/) before using any of the services here. ### Making HTTP Requests Directly ### If Google Authentication is desired for external applications, or a Google API is not available yet in this library, HTTP requests can be made directly. If you are installing this client only to authenticate your own HTTP client requests, you should use [`google/auth`](https://github.com/googleapis/google-auth-library-php#call-the-apis) instead. The `authorize` method returns an authorized [Guzzle Client](http://docs.guzzlephp.org/), so any request made using the client will contain the corresponding authorization. ```php // create the Google client $client = new Google\Client(); /** * Set your method for authentication. Depending on the API, This could be * directly with an access token, API key, or (recommended) using * Application Default Credentials. */ $client->useApplicationDefaultCredentials(); $client->addScope(Google\Service\Plus::PLUS_ME); // returns a Guzzle HTTP Client $httpClient = $client->authorize(); // make an HTTP request $response = $httpClient->get('https://www.googleapis.com/plus/v1/people/me'); ``` ### Caching ### It is recommended to use another caching library to improve performance. This can be done by passing a [PSR-6](https://www.php-fig.org/psr/psr-6/) compatible library to the client: ```php use League\Flysystem\Adapter\Local; use League\Flysystem\Filesystem; use Cache\Adapter\Filesystem\FilesystemCachePool; $filesystemAdapter = new Local(__DIR__.'/'); $filesystem = new Filesystem($filesystemAdapter); $cache = new FilesystemCachePool($filesystem); $client->setCache($cache); ``` In this example we use [PHP Cache](http://www.php-cache.com/). Add this to your project with composer: ``` composer require cache/filesystem-adapter ``` ### Updating Tokens ### When using [Refresh Tokens](https://developers.google.com/identity/protocols/OAuth2InstalledApp#offline) or [Service Account Credentials](https://developers.google.com/identity/protocols/OAuth2ServiceAccount#overview), it may be useful to perform some action when a new access token is granted. To do this, pass a callable to the `setTokenCallback` method on the client: ```php $logger = new Monolog\Logger(); $tokenCallback = function ($cacheKey, $accessToken) use ($logger) { $logger->debug(sprintf('new access token received at cache key %s', $cacheKey)); }; $client->setTokenCallback($tokenCallback); ``` ### Debugging Your HTTP Request using Charles ### It is often very useful to debug your API calls by viewing the raw HTTP request. This library supports the use of [Charles Web Proxy](https://www.charlesproxy.com/documentation/getting-started/). Download and run Charles, and then capture all HTTP traffic through Charles with the following code: ```php // FOR DEBUGGING ONLY $httpClient = new GuzzleHttp\Client([ 'proxy' => 'localhost:8888', // by default, Charles runs on localhost port 8888 'verify' => false, // otherwise HTTPS requests will fail. ]); $client = new Google\Client(); $client->setHttpClient($httpClient); ``` Now all calls made by this library will appear in the Charles UI. One additional step is required in Charles to view SSL requests. Go to **Charles > Proxy > SSL Proxying Settings** and add the domain you'd like captured. In the case of the Google APIs, this is usually `*.googleapis.com`. ### Controlling HTTP Client Configuration Directly Google API Client uses [Guzzle](http://docs.guzzlephp.org/) as its default HTTP client. That means that you can control your HTTP requests in the same manner you would for any application using Guzzle. Let's say, for instance, we wished to apply a referrer to each request. ```php use GuzzleHttp\Client; $httpClient = new Client([ 'headers' => [ 'referer' => 'mysite.com' ] ]); $client = new Google\Client(); $client->setHttpClient($httpClient); ``` Other Guzzle features such as [Handlers and Middleware](http://docs.guzzlephp.org/en/stable/handlers-and-middleware.html) offer even more control. ### Service Specific Examples ### YouTube: https://github.com/youtube/api-samples/tree/master/php ## How Do I Contribute? ## Please see the [contributing](.github/CONTRIBUTING.md) page for more information. In particular, we love pull requests - but please make sure to sign the contributor license agreement. ## Frequently Asked Questions ## ### What do I do if something isn't working? ### For support with the library the best place to ask is via the google-api-php-client tag on StackOverflow: https://stackoverflow.com/questions/tagged/google-api-php-client If there is a specific bug with the library, please [file an issue](https://github.com/googleapis/google-api-php-client/issues) in the GitHub issues tracker, including an example of the failing code and any specific errors retrieved. Feature requests can also be filed, as long as they are core library requests, and not-API specific: for those, refer to the documentation for the individual APIs for the best place to file requests. Please try to provide a clear statement of the problem that the feature would address. ### I want an example of X! ### If X is a feature of the library, file away! If X is an example of using a specific service, the best place to go is to the teams for those specific APIs - our preference is to link to their examples rather than add them to the library, as they can then pin to specific versions of the library. If you have any examples for other APIs, let us know and we will happily add a link to the README above! ### Why do some Google\Service classes have weird names? ### The _Google\Service_ classes are generally automatically generated from the API discovery documents: https://developers.google.com/discovery/. Sometimes new features are added to APIs with unusual names, which can cause some unexpected or non-standard style naming in the PHP classes. ### How do I deal with non-JSON response types? ### Some services return XML or similar by default, rather than JSON, which is what the library supports. You can request a JSON response by adding an 'alt' argument to optional params that is normally the last argument to a method call: ```php $opt_params = array( 'alt' => "json" ); ``` ### How do I set a field to null? ### The library strips out nulls from the objects sent to the Google APIs as its the default value of all of the uninitialized properties. To work around this, set the field you want to null to `Google\Model::NULL_VALUE`. This is a placeholder that will be replaced with a true null when sent over the wire. ## Code Quality ## Run the PHPUnit tests with PHPUnit. You can configure an API key and token in BaseTest.php to run all calls, but this will require some setup on the Google Developer Console. phpunit tests/ ### Coding Style To check for coding style violations, run ``` vendor/bin/phpcs src --standard=style/ruleset.xml -np ``` To automatically fix (fixable) coding style violations, run ``` vendor/bin/phpcbf src --standard=style/ruleset.xml ``` includes/google-api-8/SECURITY.md 0000644 00000000511 15021152110 0012314 0 ustar 00 # Security Policy To report a security issue, please use [g.co/vulnz](https://g.co/vulnz).

*
* It is, each time if called, the responsibility of _setupInlineCrypt():
*
* - to set $this->inline_crypt to a valid and fully working callback function
* as a (faster) replacement for encrypt() / decrypt()
*
* - NOT to create unlimited callback functions (for memory reasons!)
* no matter how often _setupInlineCrypt() would be called. At some
* point of amount they must be generic re-useable.
*
* - the code of _setupInlineCrypt() it self,
* and the generated callback code,
* must be, in following order:
* - 100% safe
* - 100% compatible to encrypt()/decrypt()
* - using only php5+ features/lang-constructs/php-extensions if
* compatibility (down to php4) or fallback is provided
* - readable/maintainable/understandable/commented and... not-cryptic-styled-code :-)
* - >= 10% faster than encrypt()/decrypt() [which is, by the way,
* the reason for the existence of _setupInlineCrypt() :-)]
* - memory-nice
* - short (as good as possible)
*
* Note: - _setupInlineCrypt() is using _createInlineCryptFunction() to create the full callback function code.
* - In case of using inline crypting, _setupInlineCrypt() must extend by the child \phpseclib3\Crypt\* class.
* - The following variable names are reserved:
* - $_* (all variable names prefixed with an underscore)
* - $self (object reference to it self. Do not use $this, but $self instead)
* - $in (the content of $in has to en/decrypt by the generated code)
* - The callback function should not use the 'return' statement, but en/decrypt'ing the content of $in only

*
* - avoiding 1000's of function calls of ie _encryptBlock()
