Returns:

the Decryptor for decryption.

newEncryptorUnsafe

public Encryptor newEncryptorUnsafe(Key encryptionKey)

Description copied from interface: CryptorFactory

Please use typesafe newDecryptor method instead to avoid mistakes (passing wrong Key).

Specified by:

newEncryptorUnsafe in interface CryptorFactory

the deserialized SignatureBinary.

newHashCreator

public HashCreator newHashCreator()

Specified by:

newHashCreator in interface HashFactory

Returns:

Specified by:

getSignatureFactoryWithoutHash in interface SignatureProcessorFactory<S extends SignatureBinary,PR extends PrivateKey,PU extends PublicKey>

Returns:

an instance of this SignatureFactory that does not hash before signing so you can control the hashing manually and only sign the resulting hash (e.g. to reuse the hash value for further calculations).
