encrypt

First post here.

I have a asp/vb6 web app that logs in a user I want to encrypt the users identity field and pass(querystring) it to a asp.net app and then decrypt it to do a db lookup.

I've google'd it of course and found rot13, not secure enough. I've also found some hits on MD5 / RC4 but did not find any good examples of encrypt / decrypt.

Thanks,

Michael
