public abstract class Credential extends java.lang.Object implements java.io.Serializable
Credentials. The Credential class represents an abstract mechanism for checking authentication credentials. A credential instance either represents a secret, or some data that could only be derived from knowing the secret.Often a Credential is related to a Password via a one way algorithm, so while a Password itself is a Credential, a UnixCrypt or MD5 digest of a a password is only a credential that can be checked against the password.
This class includes an implementation for unix Crypt an MD5 digest.
