Welcome to JavaRanch.

The Java API to perform encryption.decryption is called JCE, and there's an article on how to use it with DES linked in the Security FAQ.

DES is a heavily broken algorithm and there is no reason to use it. It's no longer encryption and can be "broken" in almost real time. DO NOT USE IT. Use AES.
