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.
