SignatureConfig

public SignatureConfig(SignatureFactory<S> signatureFactory,
                       HashConfig hashConfig,
                       String signingAlgorithm,
                       String hashAlgorithm,
                       SecurityProvider provider)

The constructor.

Parameters:

SignatureConfig

private SignatureConfig(SignatureFactory<S> signatureFactory,
                        SignatureAlgorithm signatureAlgorithm,
                        HashConfig hashConfig,

Method Detail

getSignatureAlgorithm

public SignatureAlgorithm getSignatureAlgorithm()

Returns:

the structured SignatureAlgorithm.

getHashConfig

public HashConfig getHashConfig()

Returns:

the optional HashConfig used for hashing. If not null the data to sign will be first hashed using this configuration and the resulting hash will then be signed using signature algorithm.

getSignatureFactory

public SignatureFactory<S> getSignatureFactory()

Returns:

the SignatureFactory.

withoutHashConfig

public SignatureConfig<S> withoutHashConfig()

Returns:

a copy of this SignatureConfig without hash config (set to null).
