Java Cryptography

Name

Class javax.crypto.SecretKeyFactory

Description

A SecretKeyFactory is used to convert between secret key data formats. For example, you might use a SecretKeyFactory to convert a DES SecretKey into an array of bytes, or to some other representation (a KeySpec). Similarly, a SecretKeyFactory can translate from a KeySpec to a SecretKey. As usual, you can obtain a SecretKeyFactory for a particular algorithm by calling getInstance(). You can translate from a SecretKey to a KeySpec using translateKey(). If you want to create a SecretKey from a corresponding KeySpec, use generateSecret().
