```
Example encode/decode headers
-------
Decoding the JWT headers without verifying the JWT first is NOT recommended, and is not supported by
this library. This is because without verifying the JWT, the header values could have been tampered with.
Any value pulled from an unverified header should be treated as if it could be any string sent in from an
attacker. If this is something you still want to do in your application for whatever reason, it's possible to
decode the header values manually simply by calling `json_decode` and `base64_decode` on the JWT
header part:
```php
use Firebase\JWT\JWT;
$key = 'example_key';
$payload = [
'iss' => 'http://example.org',
'aud' => 'http://example.com',
'iat' => 1356999524,
'nbf' => 1357000000
];
$headers = [
'x-forwarded-for' => 'www.google.com'
];
// Encode headers in the JWT string
$jwt = JWT::encode($payload, $key, 'HS256', null, $headers);
// Decode headers from the JWT string WITHOUT validation
// **IMPORTANT**: This operation is vulnerable to attacks, as the JWT has not yet been verified.
// These headers could be any value sent by an attacker.
list($headersB64, $payloadB64, $sig) = explode('.', $jwt);
$decoded = json_decode(base64_decode($headersB64), true);

[#165](https://github.com/firebase/php-jwt/pull/165). Thanks [@akeeman](https://github.com/akeeman),
[@chinedufn](https://github.com/chinedufn), and [@bshaffer](https://github.com/bshaffer)!
The `CachedKeySet` class can be used to fetch and cache JWKS (JSON Web Key Sets) from a public URI.
This has the following advantages:
#### 4.0.0 / 2016-07-17
- Add support for late static binding. See [#88](https://github.com/firebase/php-jwt/pull/88) for details. Thanks to [@chappy84](https://github.com/chappy84)!
- Use static `$timestamp` instead of `time()` to improve unit testing. See [#93](https://github.com/firebase/php-jwt/pull/93) for details. Thanks to [@josephmcdermott](https://github.com/josephmcdermott)!
- Fixes to exceptions classes. See [#81](https://github.com/firebase/php-jwt/pull/81) for details. Thanks to [@Maks3w](https://github.com/Maks3w)!
- Fixes to PHPDoc. See [#76](https://github.com/firebase/php-jwt/pull/76) for details. Thanks to [@akeeman](https://github.com/akeeman)!
1. The results are cached for performance.
2. If an unrecognized key is requested, the cache is refreshed, to accomodate for key rotation.
3. If rate limiting is enabled, the JWKS URI will not make more than 10 requests a second.
#### 3.0.0 / 2015-07-22
- Minimum PHP version updated from `5.2.0` to `5.3.0`.
- Add `\Firebase\JWT` namespace. See
[#59](https://github.com/firebase/php-jwt/pull/59) for details. Thanks to
[@Dashron](https://github.com/Dashron)!
- Require a non-empty key to decode and verify a JWT. See
[#60](https://github.com/firebase/php-jwt/pull/60) for details. Thanks to
[@sjones608](https://github.com/sjones608)!
- Cleaner documentation blocks in the code. See
[#62](https://github.com/firebase/php-jwt/pull/62) for details. Thanks to
[@johanderuijter](https://github.com/johanderuijter)!
```php
use Firebase\JWT\CachedKeySet;
use Firebase\JWT\JWT;
#### 2.2.0 / 2015-06-22
- Add support for adding custom, optional JWT headers to `JWT::encode()`. See
[#53](https://github.com/firebase/php-jwt/pull/53/files) for details. Thanks to
[@mcocaro](https://github.com/mcocaro)!
// The URI for the JWKS you wish to cache the results from
$jwksUri = 'https://www.gstatic.com/iap/verify/public_key-jwk';
#### 2.1.0 / 2015-05-20
- Add support for adding a leeway to `JWT:decode()` that accounts for clock skew
between signing and verifying entities. Thanks to [@lcabral](https://github.com/lcabral)!
- Add support for passing an object implementing the `ArrayAccess` interface for
`$keys` argument in `JWT::decode()`. Thanks to [@aztech-dev](https://github.com/aztech-dev)!
// Create an HTTP client (can be any PSR-7 compatible HTTP client)
$httpClient = new GuzzleHttp\Client();
#### 2.0.0 / 2015-04-01
- **Note**: It is strongly recommended that you update to > v2.0.0 to address
known security vulnerabilities in prior versions when both symmetric and
asymmetric keys are used together.
- Update signature for `JWT::decode(...)` to require an array of supported
algorithms to use when verifying token signatures.
// Create an HTTP request factory (can be any PSR-17 compatible HTTP request factory)
$httpFactory = new GuzzleHttp\Psr\HttpFactory();
// Create a cache item pool (can be any PSR-6 compatible cache item pool)
$cacheItemPool = Phpfastcache\CacheManager::getInstance('files');
$keySet = new CachedKeySet(
$jwksUri,
$httpClient,
$httpFactory,
$cacheItemPool,
null, // $expiresAfter int seconds to set the JWKS to expire
true // $rateLimit true to enable rate limit of 10 RPS on lookup of invalid keys
);
$jwt = 'eyJhbGci...'; // Some JWT signed by a key from the $jwkUri above
$decoded = JWT::decode($jwt, $keySet);
```
Miscellaneous
-------------
#### Exception Handling
When a call to `JWT::decode` is invalid, it will throw one of the following exceptions:
```php
use Firebase\JWT\JWT;
use Firebase\JWT\SignatureInvalidException;
use Firebase\JWT\BeforeValidException;
use Firebase\JWT\ExpiredException;
use DomainException;
use InvalidArgumentException;
use UnexpectedValueException;
try {
$decoded = JWT::decode($payload, $keys);
} catch (InvalidArgumentException $e) {
// provided key/key-array is empty or malformed.
} catch (DomainException $e) {
// provided algorithm is unsupported OR
// provided key is invalid OR
// unknown error thrown in openSSL or libsodium OR
// libsodium is required but not available.
} catch (SignatureInvalidException $e) {
// provided JWT signature verification failed.
} catch (BeforeValidException $e) {
// provided JWT is trying to be used before "nbf" claim OR
// provided JWT is trying to be used before "iat" claim.
} catch (ExpiredException $e) {
// provided JWT is trying to be used after "exp" claim.
} catch (UnexpectedValueException $e) {
// provided JWT is malformed OR
// provided JWT is missing an algorithm / using an unsupported algorithm OR
// provided JWT algorithm does not match provided key OR
// provided key ID in key/key-array is empty or invalid.
}
```
All exceptions in the `Firebase\JWT` namespace extend `UnexpectedValueException`, and can be simplified
like this:
```php
try {
$decoded = JWT::decode($payload, $keys);
} catch (LogicException $e) {
// errors having to do with environmental setup or malformed JWT Keys
} catch (UnexpectedValueException $e) {
// errors having to do with JWT signature and claims
}
```
#### Casting to array
The return value of `JWT::decode` is the generic PHP object `stdClass`. If you'd like to handle with arrays
instead, you can do the following:
```php
// return type is stdClass
$decoded = JWT::decode($payload, $keys);
// cast to array
$decoded = json_decode(json_encode($decoded), true);
```
