    Do you just want a general encryption and decryption support that will work on any files? There are some classes with good algorithms in the java.security package.

    You may want to go through Java's built in security classes before looking elsewhere. Try the following link:

    The cipher part is here:

    Are you talking about obfuscation of your code so that it cannot be reconstructed just by a code inspector? Do a search using your favorite search engine for "java code obfuscator" and you should find many references which will help you design a system to protect your source code.
