How to Protect my Art Resources

I am developing games. I have protecting my art resources through winzip using password protection.

but i feel it is less security.I have to give more security for my art resources. I have plan to implement

encryption algorithm such as md5 or rsa to protect my art resources.

Is there any built in md5 or rsa algorith in torque.could any one give me an idea about how to

implement md5 or rsa algorithm or any other way to protect my art resources.

Thanks and Regards
