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 \JsonSerializable interface such as JWK or JWKSet

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 (DEF)	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
PS256, PS384 and PS512	YES
none	YES	Please note that this is not a secured algorithm. USE IT WITH CAUTION!
EdDSA with Ed25519 curve	YES	With PHP 7.1, third party extension highly recommended
EdDSA with Ed448 curve	NO	No extension or built-in implementation available

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

ECDH-ES with X25519 curve	YES
ECDH-ES with X448 curve	NO

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.
