  org.apache.directory.server.kerberos.shared.crypto.encryption.RandomKeyFactory

public class RandomKeyFactory
extends Object

A factory class for producing random keys, suitable for use as session keys. For a list of desired cipher types, Kerberos random-to-key functions are used to derive keys for DES-, DES3-, AES-, and RC4-based encryption types.
