Method Detail

supportedJWSAlgorithms

public java.util.Set<JWSAlgorithm> supportedJWSAlgorithms()

Description copied from interface: JWSProvider

Returns the names of the supported algorithms by the JWS provider instance. These correspond to the alg JWS header parameter.

Specified by:

supportedJWSAlgorithms in interface JWSProvider

Returns:

The supported JWS algorithms, empty set if none.

getJCAContext

public JCAContext getJCAContext()

Description copied from interface: JCAAware

Returns the Java Cryptography Architecture (JCA) context. May be used to set a specific JCA security provider or secure random generator.

Specified by:

getJCAContext in interface JCAAware<JCAContext>

Returns:

The JCA context. Not null.

createJWSSigner

public JWSSigner createJWSSigner(JWK key)
                          throws JOSEException

Description copied from interface: JWSSignerFactory

Create a JWS signer based on the key.

Specified by:

createJWSSigner in interface JWSSignerFactory

Throws:

JOSEException

public JWSSigner createJWSSigner(JWK key,
                                 JWSAlgorithm alg)
                          throws JOSEException

Description copied from interface: JWSSignerFactory

Create a JWS signer based on the key and algorithm. Ensures that the key supports the given algorithm.

Specified by:

createJWSSigner in interface JWSSignerFactory

Throws:

JOSEException
