Client Side Encryption

I am currently trying to figure out the best way to encrypt a file with 128bit encryption and compress it on the client’s side. It needs to stay encrypted at all times until someone purposely unzips it with WinZip.

My main concern right now is encrypting it on the client’s side.

I thought of Java but I couldn't find any information/references. I think that's because so many people out there use what I'm trying to do for malicious purposes.

So then I turned to visual basic. I actually created a program, but that turned out to flop too, because it required the client to download the program.

At this point I just want to find out what other people think would work and what is recommended. Any help would be appreciated.


Thanks,

Justin
