All Implemented Interfaces:

AlgorithmNameProvider, KeyIdentityProvider, KeyPairProvider, KeySizeIndicator

public class SimpleGeneratorHostKeyProvider
extends AbstractGeneratorHostKeyProvider

A simple implementation of an AbstractGeneratorHostKeyProvider that writes and reads host keys using the OpenSSH file format. Legacy keys written by earlier implementations used Java serialization. De-serializing is restricted to a small number of classes known to exist in serialized KeyPairs.
