JWS or JWE objects support every input that can be encoded into JSON:
string, array, integer, float...
Objects that implement the \JsonSerializable interface such as JWK or JWKSet
The detached payload is supported.
Compact JSON Serialization Syntax for JWS and JWE
Flattened JSON Serialization Syntax for JWS and JWE
General JSON Serialization Syntax for JWS and JWE
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.
JWKSet is fully supported.
Other signature algorithms like RS1, HS1 or HS256/64 are also available. These algorithms should be used for testing purpose only or for compatibility with old systems
Other encryption algorithms like RSA-OEAP-384 or ChaCha20-Poly1305 are also available. These algorithms should be used for testing purpose only or for compatibility with old systems
For the ECDH-ES with X25519 curve with PHP 7.1, the third party extension highly recommended
The algorithms RSA1_5 and RSA-OAEP are now deprecated. Please use with caution.
Other encryption algorithms like A128CTR, A192CTR and A256CTR are also available. These algorithms should be used for testing purpose only or for compatibility with old systems
