SecretKey

Class Overview

A secret (symmetric) key.

This interface contains no methods or constants. Its only purpose is to group (and provide type safety for) secret keys.

Provider implementations of this interface must overwrite the equals and hashCode methods inherited from java.lang.Object, so that secret keys are compared based on their underlying key material and not based on reference.

Keys that implement this interface return the string RAW as their encoding format (see getFormat), and return the raw key bytes as the result of a getEncoded method call. (The getFormat and getEncoded methods are inherited from the java.security.Key parent interface.)

Summary

[Expand] Inherited Constants
From interface java.security.Key long serialVersionUID The class fingerprint that is set to indicate serialization compatibility with a previous version of the class.

[Expand] Inherited Methods
From interface java.security.Key abstract String getAlgorithm() Returns the standard algorithm name for this key. abstract byte[] getEncoded() Returns the key in its primary encoding format, or null if this key does not support encoding. abstract String getFormat() Returns the name of the primary encoding format of this key, or null if this key does not support encoding.
