Interface SignatureSigner

All Known Implementing Classes:
X931SignatureSigner, PSSSignatureSigner, PKCS1SignatureSigner, NullSignatureSigner, ECNRSignatureSigner, ECDSASignatureSigner, DSASignatureSigner

public interface SignatureSigner

Defines the methods required for each signing class that provides a signature engine. The methods will provide the necessary functionality for all signing applications. More information on the specific methods can be found in the implementing classes.

See SignatureSignerFactory to create a SignatureSigner.
