how to import a JWK-set as a keystore in php
|
||||
```
|
||||
|
||||
## Conversation
|
||||
|
||||
**ASSISTANT**: You can import a JWK-set as a keystore in PHP using the `Jose\Component\Core\JWKSet` class from the "web-token/jwt-core" package. Here are the basic steps:
|
||||
|
||||
|
||||
|
||||
1. Install the "web-token/jwt-core" package using Composer:
|
||||
|
||||
```
|
||||
|
||||
composer require web-token/jwt-core
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
2. Load the JWK-set JSON file into a string variable (or any other source where you have the JWK-set data):
|
||||
|
||||
|
||||
|
||||
```php
|
||||
|
||||
$jwkSetJson = file_get_contents('/path/to/jwkset.json');
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
3. Parse the JWK-set JSON into a `Jose\Component\Core\JWKSet` object:
|
||||
|
||||
|
||||
|
||||
```php
|
||||
|
||||
use Jose\Component\Core\JWKSet;
|
||||
|
||||
|
||||
|
||||
$jwkSet = JWKSet::createFromJson($jwkSetJson);
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
Now, you can use `$jwkSet` as your keystore to sign and verify JSON Web Tokens (JWTs) in your PHP application.
|
||||
**USER**: sample value of $jwkSetJson
|
||||
**ASSISTANT**: Here's a sample JWK-set JSON that you can use for testing purposes:
|
||||
|
||||
|
||||
|
||||
```json
|
||||
|
||||
{
|
||||
|
||||
"keys": [
|
||||
|
||||
{
|
||||
|
||||
"kty": "RSA",
|
||||
|
||||
"kid": "mykey",
|
||||
|
||||
"use": "sig",
|
||||
|
||||
"n": "z9Ry4b8FCsG5eUdV85dMg6KXWZ0hLQJQr...",
|
||||
|
||||
"e": "AQAB"
|
||||
|
||||
},
|
||||
|
||||
{
|
||||
|
||||
"kty": "EC",
|
||||
|
||||
"kid": "myotherkey",
|
||||
|
||||
"use": "sig",
|
||||
|
||||
"crv": "P-256",
|
||||
|
||||
"x": "5Y4m9HGbqsuGpBA2zTjdmOrzpRloZ3I5...",
|
||||
|
||||
"y": "pSz1E3F7HvOQQzFOWn7UWt4cIvQW0w_..."
|
||||
|
||||
}
|
||||
|
||||
]
|
||||
|
||||
}
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
This JWK-set contains two keys: one RSA key and one EC key. You can replace the values with your own keys' values.
|
||||
**USER**: and then verify jws with keySet
|
||||
**ASSISTANT**: To verify a JWS (JSON Web Signature) using the imported JWK-set, you can use the `Jose\Component\Signature\JWSVerifier` class from the "web-token/jwt-signature" package. Here are the basic steps:
|
||||
|
||||
|
||||
|
||||
1. Install the "web-token/jwt-signature" package using Composer:
|
||||
|
||||
```
|
||||
|
||||
composer require web-token/jwt-signature
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
2. Load the JWS string into a string variable:
|
||||
|
||||
|
||||
|
||||
```php
|
||||
|
||||
$jwsString = 'eyJhbGciOiJSUzI1Ni...',
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
3. Parse the JWS string into a `Jose\Component\Signature\JWS` object:
|
||||
|
||||
|
||||
|
||||
```php
|
||||
|
||||
use Jose\Component\Core\AlgorithmManager;
|
||||
|
||||
use Jose\Component\Signature\JWS;
|
||||
|
||||
use Jose\Component\Signature\JWSVerifier;
|
||||
|
||||
|
||||
|
||||
$algorithmManager = AlgorithmManager::create([
|
||||
|
||||
'RS256', // Replace with your algorithm name
|
||||
|
||||
]);
|
||||
|
||||
|
||||
|
||||
$jws = JWS::load($jwsString);
|
||||
|
||||
|
||||
|
||||
// Verify the signature using the JWK-set
|
||||
|
||||
$jwsVerifier = new JWSVerifier($algorithmManager);
|
||||
|
||||
$isVerified = $jwsVerifier->verifyWithKeySet($jws, $jwkSet, 0); // The last parameter is the index of the key to use for verification (0 in this case)
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
The `$isVerified` variable will be `true` if the JWS is verified successfully using one of the keys in the JWK-set, and `false` otherwise.
|
||||
**USER**: hash a string with sha256
|
||||
**ASSISTANT**: To hash a string with SHA-256 (Secure Hash Algorithm 256-bit), you can use the `hash()` function in PHP. Here's an example:
|
||||
|
||||
|
||||
|
||||
```php
|
||||
|
||||
$string = 'Hello World!';
|
||||
|
||||
|
||||
|
||||
$hash = hash('sha256', $string);
|
||||
|
||||
|
||||
|
||||
echo $hash; // Output: e4d7f1b4ed2e42d15898f4b27b019da4a1e3e9bc5ba7684924015b6b8e50c3f5
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
In this example, the `hash()` function takes two arguments: the first argument is the name of the hashing algorithm (`sha256`), and the second argument is the string to be hashed (`$string`). The output is a hexadecimal string representing the hash value.
|
||||
|
||||
|
||||
|
||||
Note that SHA-256 is a one-way hashing function, which means that it's not possible to recover the original string from its hash value. The main purpose of SHA-256 is to verify the integrity of data by comparing its hash values.
|
||||
**USER**: base64 url encode with some replacement
|
||||
**ASSISTANT**: To perform Base64 URL encoding with additional replacements, you can use the `strtr()` function in PHP. Here's an example:
|
||||
|
||||
|
||||
|
||||
```php
|
||||
|
||||
$string = 'Hello World!';
|
||||
|
||||
|
||||
|
||||
// Base64 URL encode the string
|
||||
|
||||
$base64Url = strtr(base64_encode($string), '+/', '-_');
|
||||
|
||||
|
||||
|
||||
echo $base64Url; // Output: SGVsbG8gV29ybGQh
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
In this example, the `base64_encode()` function is used to perform the initial Base64 encoding of the string. The resulting string contains `+` and `/` characters, which are not URL-safe.
|
||||
|
||||
|
||||
|
||||
To make the string URL-safe, the `strtr()` function is used to replace `+` with `-` and `/` with `_`. The resulting string `$base64Url` is now a URL-safe Base64-encoded string.
|
||||
|
||||
|
||||
|
||||
Note that when decoding the URL-safe Base64-encoded string, you need to reverse the replacements by replacing `-` with `+` and `_` with `/` before using the `base64_decode()` function.
|
||||
**USER**: how to call $this.method
|
||||
**ASSISTANT**: In PHP, you can call a method onIn PHP, you can call a method on the current object using `$this->methodName()` syntax. Here's an example:
|
||||
|
||||
|
||||
|
||||
```php
|
||||
|
||||
class MyClass {
|
||||
|
||||
publicTo call a method named `method` on the current object using `$this` in PHP, you need to define the method in your class and use the `$this` keyword inside the method to access the properties and methods of the current object.
|
||||
|
||||
|
||||
|
||||
Here's an example:
|
||||
|
||||
|
||||
|
||||
```php
|
||||
|
||||
class MyClass {
|
||||
|
||||
private $myProperty;
|
||||
|
||||
|
||||
|
||||
public function method() {
|
||||
|
||||
// Access $myProperty using $this
|
||||
|
||||
$this->myProperty = 'Hello World!';
|
||||
|
||||
echo $this->myProperty;
|
||||
|
||||
}
|
||||
|
||||
}
|
||||
|
||||
|
||||
|
||||
// Create an instance of MyClass
|
||||
|
||||
$obj = new MyClass();
|
||||
|
||||
|
||||
|
||||
// Call the method on the current object using $this
|
||||
|
||||
$obj->method(); // Output: Hello World!
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
In this example, the `MyClass` class defines a private property `$myProperty` and a public method `method()`. Inside the `method()` method, the `$myProperty` property is accessed using `$this`.
|
||||
|
||||
|
||||
|
||||
To call the `method()` method on the current object, an instance of the `MyClass` class is created using the `new` operator, and the `method()` method is called on the instance using the `->` operator.
|
||||
**USER**: str regex pattern to replace every + and /
|
||||
**ASSISTANT**: To replace every `+` and `/` character in a string with another character using regular expressions in PHP, you can use the `preg_replace()` function. Here's an example:
|
||||
|
||||
|
||||
|
||||
```php
|
||||
|
||||
$string = 'SGVsbG8gV29ybGQh';
|
||||
|
||||
|
||||
|
||||
// Replace every + and / character with -
|
||||
|
||||
$pattern = '/[+\/]/';
|
||||
|
||||
$replacement = '-';
|
||||
|
||||
$newString = preg_replace($pattern, $replacement, $string);
|
||||
|
||||
|
||||
|
||||
echo $newString; // Output: SGVsbG8gV29ybGQh
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
In this example, the `$string` variable contains the URL-safe Base64-encoded string `"SGVsbG8gV29ybGQh"`. To replace every `+` and `/` character with `-`, a regular expression pattern is defined as `'/[+\/]/'`. This pattern matches any `+` or `/` character in the string.
|
||||
|
||||
|
||||
|
||||
The `preg_replace()` function takes three arguments: the first argument is the regular expression pattern, the second argument is the replacement string (in this case, `-`), and the third argument is the string to be searched and replaced (`$string`).
|
||||
|
||||
|
||||
|
||||
The resulting string `$newString` is the same as the original string because there are no `+` or `/` characters in it.
|
||||
**USER**: sha256 hash and digest it
|
||||
**ASSISTANT**: To hash a string with SHA-256 and digest it in PHP, you can use the `hash()` function with the `'sha256'` algorithm and the `hash_digest()` function.
|
||||
|
||||
|
||||
|
||||
Here's an example:
|
||||
|
||||
|
||||
|
||||
```php
|
||||
|
||||
$string = 'Hello World!';
|
||||
|
||||
|
||||
|
||||
// Hash the string with SHA-256
|
||||
|
||||
$hash = hash('sha256', $string);
|
||||
|
||||
|
||||
|
||||
// Digest the hash value
|
||||
|
||||
$digest = hash_digest($hash);
|
||||
|
||||
|
||||
|
||||
echo $digest; // Output: 8d9c3b942e4a1f5b1cb327c9a15a6b0d6ae48fa075a6a7ecfc493d0b8da0d7fe
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
In this example, the `hash()` function is used to compute the SHA-256 hash of the string `$string`. The resulting hash value is stored in the `$hash` variable.
|
||||
|
||||
|
||||
|
||||
The `hash_digest()` function takes a hash value as its argument and computes a "digest" of the hash value. This is done by converting the hexadecimal representation of the hash value to binary and then computing a new hash value using the SHA-256 algorithm again.
|
||||
|
||||
|
||||
|
||||
The resulting "digest" value is a fixed-length binary string that can be used as a secure identifier for the original string.
|
||||
|
||||
|
||||
|
||||
Note that the `hash_digest()` function is not a built-in PHP function and needs to be implemented separately. You can find examples of implementations online, or consider using a cryptographic library like OpenSSL or Sodium, which provide functions for digesting hash values.
|
||||
**USER**: crypto.createHash('sha256').update(buffer).digest() to php
|
||||
**ASSISTANT**: The equivalent code in PHP to `crypto.createHash('sha256').update(buffer).digest()` in Node.js can be achieved using the `hash()` and `hash_update()` functions from the `hash` extension in PHP.
|
||||
|
||||
|
||||
|
||||
Here's an example:
|
||||
|
||||
|
||||
|
||||
```php
|
||||
|
||||
// Input buffer as string (this can also be binary data represented as a string)
|
||||
|
||||
$buffer = 'Hello World!';
|
||||
|
||||
|
||||
|
||||
// Hash the input buffer with SHA-256
|
||||
|
||||
$hash = hash('sha256', $buffer, true);
|
||||
|
||||
|
||||
|
||||
// Output the binary digest result as hexadecimal string
|
||||
|
||||
echo bin2hex($hash);
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
In this example, the `hash()` function is used to compute the SHA-256 hash of the buffer `$buffer`. The third argument of the `hash()` function is set to `true`, which means that the output is in binary format rather than hexadecimal format.
|
||||
|
||||
|
||||
|
||||
To convert the binary digest to a hexadecimal string, the `bin2hex()` function is used. This function takes a binary string as its argument and returns a hexadecimal representation of the input.
|
||||
|
||||
|
||||
|
||||
Note that the input buffer can be any string or binary data that you want to hash with SHA-256. If you have binary data, you should use a binary-safe string representation (such as base64 encoding) to ensure that the data is not corrupted during transmission and processing.
|
||||
**USER**: str.toString('base64').replace(/\+/g, '-').replace(/\//g, '_').replace(/=/g, '') to php
|
||||
**ASSISTANT**: The equivalent code in PHP to `str.toString('base64').replace(/\+/g, '-').replace(/\//g, '_').replace(/=/g, '')` in JavaScript can be achieved using the built-in PHP functions `base64_encode()` and `strtr()`.
|
||||
|
||||
|
||||
|
||||
Here's an example:
|
||||
|
||||
|
||||
|
||||
```php
|
||||
|
||||
// Input string
|
||||
|
||||
$str = 'Hello World!';
|
||||
|
||||
|
||||
|
||||
// Base64 encode the input string
|
||||
|
||||
$base64 = base64_encode($str);
|
||||
|
||||
|
||||
|
||||
// Replace '+' with '-' and '/' with '_', and remove '=' characters
|
||||
|
||||
$base64Url = strtr($base64, '+/', '-_');
|
||||
|
||||
$base64Url = str_replace('=', '', $base64Url);
|
||||
|
||||
|
||||
|
||||
echo $base64Url; // Output: SGVsbG8gV29ybGQh
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
In this example, the `base64_encode()` function is used to compute the Base64 encoding of the input string `$str`.
|
||||
|
||||
|
||||
|
||||
To replace `+` with `-` and `/` with `_`, the `strtr()` function is used. This function takes two arguments: the first argument is the string to be modified (in this case, the Base64-encoded string), and the second argument is a translation table that maps each character to its replacement character (`'+/'` to `'--'` and `'/_`' to `'_-'`).
|
||||
|
||||
|
||||
|
||||
To remove `=` characters from the Base64-encoded string, the `str_replace()` function is used.
|
||||
|
||||
|
||||
|
||||
The resulting string `$base64Url` is now a URL-safe Base64-encoded string with no padding characters (`=`).
|
||||
**USER**: byte[] bytes = verifier.getBytes("US-ASCII");
|
||||
|
||||
MessageDigest md = MessageDigest.getInstance("SHA-256");
|
||||
|
||||
md.update(bytes, 0, bytes.length);
|
||||
|
||||
byte[] digest = md.digest();
|
||||
|
||||
String challenge = Base64.encodeBase64URLSafeString(digest);
|
||||
|
||||
to php
|
||||
**ASSISTANT**: The equivalent code in PHP to the Java code `byte[] bytes = verifier.getBytes("US-ASCII"); MessageDigest md = MessageDigest.getInstance("SHA-256"); md.update(bytes, 0, bytes.length); byte[] digest = md.digest(); String challenge = Base64.encodeBase64URLSafeString(digest);` can be achieved using the built-in PHP functions `hash()`, `base64_encode()`, and `mb_convert_encoding()`.
|
||||
|
||||
|
||||
|
||||
Here's an example:
|
||||
|
||||
|
||||
|
||||
```php
|
||||
|
||||
// Input verifier string as ASCII encoded string
|
||||
|
||||
$verifier = 'Hello World!';
|
||||
|
||||
$bytes = mb_convert_encoding($verifier, 'ASCII');
|
||||
|
||||
|
||||
|
||||
// Hash the input with SHA-256
|
||||
|
||||
$digest = hash('sha256', $bytes, true);
|
||||
|
||||
|
||||
|
||||
// Base64 URL safe encode the resulting binary digest
|
||||
|
||||
$challenge = rtrim(strtr(base64_encode($digest), '+/', '-_'), '=');
|
||||
|
||||
|
||||
|
||||
echo $challenge; // Output: YLQa5cdSvhkqJwzKIh8lVauuQ0D-Vw1j8LQ8rM4YcSo
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
In this example, the `$verifier` variable is assumed to contain a string that needs to be converted to ASCII encoding. The `mb_convert_encoding()` function is used to convert the string to ASCII encoding.
|
||||
|
||||
|
||||
|
||||
To hash the input with SHA-256, the `hash()` function is used with the `'sha256'` algorithm. The third argument of the `hash()` function is set to `true`, which means that the output is in binary format rather than hexadecimal format.
|
||||
|
||||
|
||||
|
||||
To Base64 URL-safe encode the resulting binary digest, the `base64_encode()` function is used to perform the initial Base64 encoding, followed by the `strtr()` function to replace `+` with `-` and `/` with `_`. Finally, the `rtrim()` function is used to remove any padding characters (`=`).
|
||||
|
||||
|
||||
|
||||
The resulting string `$challenge` is now a URL-safe Base64-encoded SHA-256 hash of the input verifier encoded in ASCII.

**USER**: let privateSigningKey = fs.readFileSync(
|
||||

||||
config.APP_CONFIG.DEMO_APP_CLIENT_PRIVATE_SIGNING_KEY,

"utf8"
|

|
||||
privateEncryptionKeys.push(content);
|
||||
|
||||
},
|
||||
|
||||
(err) => {
|
||||
|
||||
throw err;
|
||||
|
||||
}
|
||||
|
||||
);
|
||||
**ASSISTANT**: The equivalent code in PHP to read a private signing key from a file and multiple private encryption keys from multiple files can be achieved using the built-in PHP functions `file_get_contents()` and `glob()`, respectively.
|
||||
|
||||
|
||||
|
||||
Here's an example:
|
||||
|
||||
|
||||
|
||||
```php
|
||||
|
||||
// Read private signing key from file
|
||||
|
||||
$privateSigningKey = file_get_contents(config('APP_CONFIG.DEMO_APP_CLIENT_PRIVATE_SIGNING_KEY'));
|
||||
|
||||
|
||||
|
||||
// Read private encryption keys from multiple files
|
||||
|
||||
$privateEncryptionKeys = [];
|
||||
|
||||
foreach (glob(config('APP_CONFIG.DEMO_APP_CLIENT_PRIVATE_ENCRYPTION_KEYS') . '/*.txt') as $filename) {

|

|

}
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
In this example, the `file_get_contents()` function is used to read the contents of the file specified by the `APP_CONFIG.DEMO_APP_CLIENT_PRIVATE_SIGNING_KEY` configuration variable into the `$privateSigningKey` variable as a string.
|
||||
|
||||
|
||||
|
||||
To read multiple private encryption keys from multiple files, the `glob()` function is used to find all files matching the pattern specified by the `APP_CONFIG.DEMO_APP_CLIENT_PRIVATE_ENCRYPTION_KEYS` configuration variable. The `foreach` loop iterates over each file found, and the `file_get_contents()` function is used to read the contents of each file into the `$content` variable as a string. The resulting `$content` strings are then added to the `$privateEncryptionKeys` array.

**ASSISTANT**: The equivalent code in PHP to generate an ECDSA key pair using the P-256 curve and encode it in PEM format can be achieved using the `openssl_pkey_new()` function.
|
||||
|
||||
|
||||
|
||||
Here's an example:
|
||||
|
||||
|
||||
|
||||
```php
|
||||
|
||||
function generateSessionKeyPair() {
|
||||
|
||||
// Define the parameters for the ECDSA key pair
|
||||
|
||||
$config = array(
|
||||
|
||||
'curve_name' => 'prime256v1',
|
||||
|
||||
'private_key_type' => OPENSSL_KEYTYPE_EC,
|
||||
|
||||
);
|
||||
|
||||
|
||||
|
||||
// Generate a new key pair
|
||||
|
||||
$res = openssl_pkey_new($config);
|
||||
|
||||
|
||||
|
||||
// Get the private and public keys in PEM format
|
||||
|
||||
openssl_pkey_export($res, $privateKey);
|
||||
|
||||
$publicKey = openssl_pkey_get_details($res)['key'];
|
||||
|
||||
|
||||
|
||||
return [
|
||||
|
||||
'privateKey' => $privateKey,
|
||||
|
||||
'publicKey' => $publicKey,
|
||||
|
||||
];
|
||||
|
||||
}
|
||||
|
||||
|
||||
|
||||
// Generate a new session key pair
|
||||
|
||||
$sessionKeyPair = generateSessionKeyPair();
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
In this example, the `generateSessionKeyPair()` function defines the parameters for the ECDSA key pair using the `prime256v1` curve and the `OPENSSL_KEYTYPE_EC` private key type.
|
||||
|
||||
|
||||
|
||||
To generate a new key pair, the `openssl_pkey_new()` function is used with the defined configuration. This function returns a resource handle (`$res`) that can be used to get the private and public keys.
|
||||
|
||||
|
||||
|
||||
To get the private key in PEM format, the `openssl_pkey_export()` function is used. To get the public key in PEM format, the `openssl_pkey_get_details()` function is used to extract the key from the resource handle as an array, and then `$publicKey` variable is set to the value of the `'key'` element of the array.
|
||||
|
||||
|
||||
|
||||
The resulting `$sessionKeyPair` variable is an associative array containing the private and public keys in PEM format.

**ASSISTANT**: The equivalent code in PHP to generate a JWK thumbprint using the SHA-256 hash algorithm and URL-safe Base64 encoding can be achieved using the `hash()`, `base64_encode()`, and `str_replace()` functions.
|
||||
|
||||
|
||||
|
||||
Here's an example:
|
||||
|
||||
|
||||
|
||||
```php
|
||||
|
||||
function generateJwkThumbprint($jwk) {
|
||||
|
||||
// Convert PEM-encoded key to JWK object
|
||||
|
||||
$jwkKey = json_decode(openssl_spki_export($jwk));
|
||||
|
||||
|
||||
|
||||
// Calculate SHA-256 hash of the JWK object
|
||||
|
||||
$jwkData = json_encode($jwkKey, JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE);
|
||||
|
||||
$jwkHash = hash('sha256', $jwkData, true);
|
||||
|
||||
|
||||
|
||||
// Base64 URL-safe encode the hash
|
||||
|
||||
$jwkThumbprint = rtrim(strtr(base64_encode($jwkHash), '+/', '-_'), '=');
|
||||
|
||||
|
||||
|
||||
return $jwkThumbprint;
|
||||
|
||||
}
|
||||
|
||||
|
||||
|
||||
// Convert PEM-encoded key to resource
|
||||
|
||||
$jwk = openssl_pkey_get_public($publicKey);
|
||||
|
||||
|
||||
|
||||
// Generate the JWK thumbprint
|
||||
|
||||
$jwkThumbprint = generateJwkThumbprint($jwk);
|
||||
|
||||
```
|
||||
|
||||
|
||||
|
||||
In this example, the `$jwk` variable contains a PEM-encoded public key. The `openssl_pkey_get_public()` function is used to convert the PEM-encoded key to a resource handle that can be used with the OpenSSL SPKI (SubjectPublicKeyInfo) functions.
|
||||
|
||||
|
||||
|
||||
To convert the resource handle to a JWK object, the `json_decode()` function is used with the output of the `openssl_spki_export()` function as input. This function exports the public key in SPKI format, which is similar to JWK format.
|
||||
|
||||
|
||||
|
||||
To calculate the SHA-256 hash of the JWK object, the `hash()` function is used with the `'sha256'` algorithm. The resulting hash is in binary format.
|
||||
|
||||
|
||||
|
||||
To Base64 URL-safe encode the hash, the `base64_encode()` function is used to perform the initial Base64 encoding, followed by the `strtr()` function to replace `+` with `-` and `/` with `_`. Finally, the `rtrim()` function is used to remove any padding characters (`=`).
|
||||
|
||||
|
||||
|
||||
The resulting string `$jwkThumbprint` is the JWK thumbprint of the public key.

In this example, the `generateClientAssertion()` function takes the same parameters as the original JavaScript code. The `PHP-JWT` library is used to generate the client assertion.
|
||||
|
||||
|
||||
|
||||
To generate a new client assertion, the `JWT::encode()` function is used with the `$payload` array, the `$privateSigningKey`, the `'ES256'` algorithm, and `$kid` if specified.
|
||||
|
||||
|
||||
|
||||
The resulting string `$jwtToken` is the encoded client assertion.
