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.

Start with the "How do I work with message digests?" article in the FAQ page I mentioned. Note that one shouldn't use SHA-1 any more, but SHA-2 instead (in the shape of SHA-256, SHA-384 or SHA-512).
