Re: Cryptography in tn5250

There is an option that you can use, somewhere under the OpenSSL pages.
You can use a SSL wrapper program.  I haven't tried this connecting to
an AS/400, but I have done it for connections between a Unix box and a
Windows box.  This required no changes to the source code of the end 
programs.
