Interface SecretKey

All Superinterfaces:
Key, Serializable
Known Subinterfaces:
Known Implementing Classes:
GnuPBEKey, KerberosKey, SecretKeySpec

public interface SecretKey
extends Key

A secret key for symmetric cryptography.

This interface defines no new methods over Key, but rather is intended to be a marker interface and to provide type safety for secret keys.

The format of secret keys should be RAW, as returned by Key.getFormat().

Concrete implementations of this interface should override the Object.equals(Object) and Object.hashCode() methods of Object to use the actual key data rather than the identity-based default methods.
