Encryption and JAVA

[Floppyman]

Hi all,

I'm looking for encryption algorithm (perhaps based off blowfish, DES, or AES) that will work with JAVA. The thing is that I need to be able to encrypt strings and all I have been able to find are implementations that encrypt arrays of bytes. Does anyone out there have any suggestions/ideas? Thanks in advance.

We once wrote a program that did exactly that. I'll try find it's code for you now
It was very basic though... you still want it, or you looking for something swish??

You can find free source code for the Blowfish algorithm on the Counterpane website, do a search for it in google.

What I did was convert the string to a byte array and then encrypt it as standard using Blowfish.

All encryption algorithms encrypt byte arrays. But that's no problem; a string is a byte array too.

This site looks like it has a Blowfish implementation in Java: http://web.bsn.ch/lasse/bfacs.htm

If you are really interested in cryptography, get the book Applied Cryptography by Bruce Schneier. It has C source code for many algorithms. It would take some work to port the code to Java, since it relies heavily on memory pointers, but it could be done.

Thanks for the replies. The information that was on the site doctorgonzo posted is what I needed. Thanks again.
