JWEJCAContext
public JWEJCAContext(Provider generalProvider, Provider keProvider, Provider ceProvider, Provider macProvider, SecureRandom randomGen)
Creates a new JCA context for JWE with the specified JCA providers and secure random generator.- Parameters:
generalProvider
- The general JCA provider to be used for all operations where a more specific one is absent,null
to use the default system provider.keProvider
- The specific JCA provider to be used for the key encryption,null
to fall back to the general one, and if that is not specified to the default system provider.ceProvider
- The specific JCA provider to be used for the content encryption,null
to fall back to the general one, and if that is not specified to the default system provider.macProvider
- The specific JCA provider to be used for the MAC computation (where required by the JWE encryption method),null
to fall back to the general one, and if that is not specified to the default system provider.randomGen
- The specific secure random generator for the initialisation vector and other purposes requiring a random number,null
to use the default system one.
