Java Cryptography

Name

Class javax.crypto.spec.DESKeySpec

Description

This class represents a key that is used with a DES symmetric cipher. This class is useful for converting between byte arrays and DES SecretKeys:

• To convert from a byte array to a SecretKey, construct a DESKeySpec from the byte array. Then use SecretKeyFactory’s generateSecret() to create the SecretKey.

• To convert from a DES SecretKey to a DESKeySpec, give the SecretKey to SecretKeyFactory’s translateKey().
