public DefaultJWSVerifierFactory()

Method Details

supportedJWSAlgorithms

public 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.

createJWSVerifier

public JWSVerifier createJWSVerifier(JWSHeader header,
 Key key)
                              throws JOSEException

Description copied from interface: JWSVerifierFactory

Creates a new JWS verifier for the specified header and key.

Specified by:

createJWSVerifier in interface JWSVerifierFactory

Parameters:

header - The JWS header. Not null.

key - The key intended to verify the JWS message. Not null.

Returns:

The JWS verifier.

Throws:

JOSEException - If the JWS algorithm is not supported or the key type or length doesn't match the expected for the JWS algorithm.
