You don't generally encrypt passwords. You simply hash them. There should rarely, if ever, be a reason to decrypt a password. http://java.sun.com/j2se/1.4.2/docs/guide/security/CryptoSpec.html http://java.sun.com/j2se/1.4.2/docs/guide/security/jce/JCERefGuide.html

in the past when i wanted to make a password non-human readable, i would base64 encode it. this is not encryption in any sense of the word, though.

The API already includes tools to perform MD5 hashing which is pretty common.
