Method Detail

supportedJWEAlgorithms

public Set<JWEAlgorithm> supportedJWEAlgorithms()

Description copied from interface: JWEProvider

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

Specified by:

supportedJWEAlgorithms in interface JWEProvider

Returns:

The supported JWE algorithms, empty set if none.

supportedEncryptionMethods

public Set<EncryptionMethod> supportedEncryptionMethods()

Description copied from interface: JWEProvider

Returns the names of the supported encryption methods by the JWE provier. These correspond to the enc JWE header parameter.

Specified by:

supportedEncryptionMethods in interface JWEProvider

Returns:

The supported encryption methods, empty set if none.

getJCAContext

public JWEJCAContext 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<JWEJCAContext>

Returns:

The JCA context. Not null.

createJWEDecrypter

public JWEDecrypter createJWEDecrypter(JWEHeader header,
                              Key key)
                                throws JOSEException

Description copied from interface: JWEDecrypterFactory

Creates a new JWE decrypter for the specified header and key.

Specified by:

createJWEDecrypter in interface JWEDecrypterFactory

Parameters:

header - The JWE header. Not null.

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

Returns:

The JWE decrypter.

Throws:

JOSEException - If the JWE algorithm / encryption method is not supported or the key type or length doesn't match expected for the JWE algorithm.
