de.profhenry.sshsig.core.JcaSingingBackend

All Implemented Interfaces:

SigningBackend<KeyPair>

public class JcaSingingBackend
extends Object
implements SigningBackend<KeyPair>

A SigningBackend using the Java Cryptography Architecture (JCA).

For signing you need to specify a KeyPair, the PrivateKey is required for the actual signing process, the PublicKey is required because it gets embedded into the SSH signature.
