The "Easy" Way

In version 2.1, an "Easy" component will be released. With this component you will be able to produce and consume tokens an easy way.

Step 1: install the package web-token/jwt-easy
Step 2: install the signature or encryption algorithms you want to use. e.g., web-token/jwt-signature-algorithm-rsa. if you do not, you may encounter an error like "The algorithm "ES256" is not supported."
Step 3: create your scripts.

JWS Creation And Verification

In the following example, we will create a signed token (JWS) with a set of standard and custom claims and headers.

use Jose\Easy\Build;

$time = time(); // The current time

$jwk = new JWK([

    ])
    ->header('prefs', ['field1', 'field7'])
    ->header('jti', '0123456789'),
    ->header('alg', 'RS512')
    ->sign($jwk)
;

echo $jws; // The variable $jws now contains your token

A token you receive can be read and verified. Verification is done on the signature and the claims or header parameters you want.

use Jose\Component\Core\JWK;
use Jose\Easy\Load;

$jwk = new JWK([
    'kty' => 'RSA',
    'kid' => 'bilbo.baggins@hobbiton.example',
    'use' => 'sig',
    'n' => 'n4EPtAOCc9AlkeQHPzHStgAbgs7bTZLwUBZdR8_KuKPEHLd4rHVTeT-O-XV2jRojdNhxJWTDvNd7nqQ0VEiZQHz_AJmSCpMaJMRBSFKrKb2wqVwGU_NsYOYL-QtiWN2lbzcEe6XC0dApr5ydQLrHqkHHig3RBordaZ6Aj-oBHqFEHYpPe7Tpe-OfVfHd1E6cS6M1FZcD1NNLYD5lFHpPI9bTwJlsde3uhGqC0ZCuEHg8lhzwOHrtIQbS0FVbb9k3-tVTU4fg_3L_vniUFAKwuCLqKnS2BYwdq_mzSnbLY7h_qixoR7jig3__kRhuaxwUkRz5iaiQkqgc5gHdrNP5zw',
    'e' => 'AQAB'
]);
$jwt = Load::jws($token) // We want to load and verify the token in the variable $token
    ->algs(['RS256', 'RS512']) // The algorithms allowed to be used
    ->exp() // We check the "exp" claim
    ->iat(10) // We check the "iat" claim. Leeway is 10s
    ->nbf() // We check the "nbf" claim
    ->aud('audience1') // Allowed audience
    ->iss('issuer') // Allowed issuer
    ->sub('subject') // Allowed subject
    ->jti('0123456789') // Token ID
    ->key($jwk) // Key used to verify the signature
    ->run() // Go!
;

If everything is ok, the variable $jwt contains a Jose\Easy\JWT object. This object has 2 properties: header and claims containing the loaded values.

$jwt->claims->all(); // All claims (array)
$jwt->claims->iat(); // = $jwt->claims->get('iat');
$jwt->claims->nbf();
$jwt->claims->exp();
$jwt->claims->jti(); // '0123456789'
$jwt->claims->iss(); // 'issuer'
$jwt->claims->sub(); // 'subject'
$jwt->claims->aud(); // ['audience1', 'audience2']
$jwt->claims->get('https://example.com/isRoot'); // true

$jwt->header->all(); // ['jti' => '0123456789', 'alg' => 'RS512', 'crit' => ['alg']]
$jwt->header->alg(); // 'RS512'
$jwt->header->jti(); // '0123456789'

JWE Creation And Decryption

The JWE creation and loading is very similar to the JWS process as they use common methods. In the following example, we will create an encrypted token (JWE) with a set of standard and custom claims and headers.

use Jose\Component\Core\JWK;
use Jose\Easy\Build;

$time = time(); // The current time

$jwk = new JWK([
    'kty' => 'RSA',
    'kid' => 'bilbo.baggins@hobbiton.example',
    'use' => 'enc',
    'n' => 'n4EPtAOCc9AlkeQHPzHStgAbgs7bTZLwUBZdR8_KuKPEHLd4rHVTeT-O-XV2jRojdNhxJWTDvNd7nqQ0VEiZQHz_AJmSCpMaJMRBSFKrKb2wqVwGU_NsYOYL-QtiWN2lbzcEe6XC0dApr5ydQLrHqkHHig3RBordaZ6Aj-oBHqFEHYpPe7Tpe-OfVfHd1E6cS6M1FZcD1NNLYD5lFHpPI9bTwJlsde3uhGqC0ZCuEHg8lhzwOHrtIQbS0FVbb9k3-tVTU4fg_3L_vniUFAKwuCLqKnS2BYwdq_mzSnbLY7h_qixoR7jig3__kRhuaxwUkRz5iaiQkqgc5gHdrNP5zw',
    'e' => 'AQAB',
]);
$jwe = Build::jwe() // We build a JWE
    ->exp($time + 3600)
    ->iat($time)
    ->nbf($time)
    ->jti('0123456789', true)
    ->iss('issuer')
    ->aud('audience1')
    ->aud('audience2')
    ->sub('subject')
    ->alg('RSA-OAEP-256') // The "alg" header parameter corresponds to the key encryption algorithm
    ->enc('A256GCM')      // The "enc" header parameter corresponds to the content encryption algorithm
    ->zip('DEF')          // We compress the payload (optional. Only recommended for large set of data)
    ->claim('is_root', true) // Custom claims
    ->claim('roles', ['ROLE1' => true, 'ROLE2' => 0.007])
    ->crit(['alg', 'enc']) // We mark some header parameters as critical
    ->encrypt($jwk) // Compute the token with the given JWK (public key)
;

echo $jwe; // The variable $jwe now contains your token

The encrypted tokens can be decrypted the same way as the signed ones.

use Jose\Component\Core\JWK;
use Jose\Easy\Load;

$jwk = new JWK([
    'kty' => 'RSA',
    'kid' => 'bilbo.baggins@hobbiton.example',
