Re[2]: [WEB400] Generating session keys in RPG using HASH values

[Anton Gombkötö <gombkoetoe@xxxxxxxxxx>]

That's what i used in a little app to add an entry (i'm doing the rest with 
Net.Data) and i'm pretty satisfied with it.
I just multiply two randoms and store user-id and ip-addr. This can be used for 
a re-start of the application, too.
