No. "Easy" conversion implies decryption, which is impossible for the DES encrypted passwords, which is impossible. I havent looked into this sort of thing myself, but I'd bet there is some gizmo that allows logins with DES passwords, but when the user finally changes the password, MD5 is used for the new entry transparently. If such a system isnt in place, I'd be very surprised. Moreover.. I might even undertake the task. That is, if someone wants to take the burden of a GUI editor/email system with builtin PGP off my hands. :) I'll gladly trade projects!
