Provided Features
Supported Input Types:
JWS or JWE objects support every input that can be encoded into JSON:
string,array,integer,float...Objects that implement the
\JsonSerializableinterface such asJWKorJWKSet
The detached payload is supported.
Supported Serialization Modes
Compact JSON Serialization Syntax for JWS and JWE
Flattened JSON Serialization Syntax for JWS and JWE
General JSON Serialization Syntax for JWS and JWE
Supported Compression Methods
Compression Method | Supported |
Deflate ( | YES |
Supported Key Types (JWK)
Key Type | Supported | Comment |
oct | YES | Symmetric keys |
RSA | YES | RSA based asymmetric keys |
EC | YES | Elliptic Curves based asymmetric keys |
OKP | YES | Octet Key Pair based asymmetric keys |
JWK objects support JSON Web Key Thumbprint (RFC 7638).
A none key type for the none algorithm. It is used to explicitly allow this unsecured algorithm.
Key Sets (JWKSet)
JWKSet is fully supported.
Supported Signature Algorithms
Signature Algorithm | Supported | Comment |
HS256, HS384 and HS512 | YES | |
ES256, ES384 and ES512 | YES | |
RS256, RS384 and RS512 | YES | |
