| decode(string $jwt,$keyOrKeyArray) X-Ref |
| Decodes a JWT string into a PHP object. param: string $jwt The JWT param: Key|array<string,Key> $keyOrKeyArray The Key or associative array of key IDs (kid) to Key objects. return: stdClass The JWT's payload as a PHP object |
| encode(array $payload,$key,string $alg,string $keyId = null,array $head = null) X-Ref |
| Converts and signs a PHP array into a JWT string. param: array<mixed> $payload PHP array param: string|resource|OpenSSLAsymmetricKey|OpenSSLCertificate $key The secret key. param: string $alg Supported algorithms are 'ES384','ES256', 'ES256K', 'HS256', param: string $keyId param: array<string, string> $head An array with header elements to attach return: string A signed JWT |
| sign(string $msg,$key,string $alg) X-Ref |
| Sign a string with a given key and algorithm. param: string $msg The message to sign param: string|resource|OpenSSLAsymmetricKey|OpenSSLCertificate $key The secret key. param: string $alg Supported algorithms are 'ES384','ES256', 'ES256K', 'HS256', return: string An encrypted message |
| verify(string $msg,string $signature,$keyMaterial,string $alg) X-Ref |
| Verify a signature with the message, key and method. Not all methods are symmetric, so we must have a separate verify and sign method. param: string $msg The original message (header and body) param: string $signature The original signature param: string|resource|OpenSSLAsymmetricKey|OpenSSLCertificate $keyMaterial For HS*, a string key works. for RS*, must be an instance of OpenSSLAsymmetricKey param: string $alg The algorithm return: bool |
| jsonDecode(string $input) X-Ref |
| Decode a JSON string into a PHP object. param: string $input JSON string return: mixed The decoded JSON string |
| jsonEncode(array $input) X-Ref |
| Encode a PHP array into a JSON string. param: array<mixed> $input A PHP array return: string JSON representation of the PHP array |
| urlsafeB64Decode(string $input) X-Ref |
| Decode a string with URL-safe Base64. param: string $input A Base64 encoded string return: string A decoded string |
| urlsafeB64Encode(string $input) X-Ref |
| Encode a string with URL-safe Base64. param: string $input The string you want encoded return: string The base64 encode of what you passed in |
| getKey($keyOrKeyArray,?string $kid) X-Ref |
| Determine if an algorithm has been provided for each Key param: Key|ArrayAccess<string,Key>|array<string,Key> $keyOrKeyArray param: string|null $kid return: Key |
| constantTimeEquals(string $left, string $right) X-Ref |
param: string $left The string of known length to compare against param: string $right The user-supplied string return: bool |
| handleJsonError(int $errno) X-Ref |
| Helper method to create a JSON error. param: int $errno An error number from json_last_error() return: void |
| safeStrlen(string $str) X-Ref |
| Get the number of bytes in cryptographic strings. param: string $str return: int |
| signatureToDER(string $sig) X-Ref |
| Convert an ECDSA signature to an ASN.1 DER sequence param: string $sig The ECDSA signature to convert return: string The encoded DER object |
| encodeDER(int $type, string $value) X-Ref |
| Encodes a value into a DER object. param: int $type DER tag param: string $value the value to encode return: string the encoded object |
| signatureFromDER(string $der, int $keySize) X-Ref |
| Encodes signature from a DER object. param: string $der binary signature in DER format param: int $keySize the number of bits in the key return: string the signature |
| readDER(string $der, int $offset = 0) X-Ref |
| Reads binary DER-encoded data and decodes into a single object param: string $der the binary data in DER format param: int $offset the offset of the data stream containing the object return: array{int, string|null} the new offset and the decoded object |
