SHA is not a cipher -which is used for reversible (or two-way) encryption-, it's a hash or digest, and is used for irreversible, or one-way, encryption. If you ever want to get back the original cleartext then you need to use a cipher such as Triple-DES or AES. The Java API for that is called JCE; you'll find more details and examples in the SecurityFaq.
