How to encrypt login/password into a session cookie?

Hello,

Here’s what I have to do:

A user access one application on a Domino server (web). He must authenticate (we use SSO-LtpaToken), and then if his login/password are correct, he is autorized to access this application.

Inside this application, there’s link to other applications which are not Domino… and not on the same server. I want to avoid them to be prompted again by this server.

I’d like to be able to send the login/password to this system, and authenticate them automaticaly. I was thinking using a cookie, write down the login/password from Domino… and the other system would just have to read it.

The problem is that a session cookie might not be saved on the disk… but some people could be able to “see” the login/password using 3rd party software. I would like to be able to prevent this… by encrypting the secret information… but I just don’t know how to do this.

Can someone help me on this?

Thanks!
