Yes, this is reversible. I use a python script to set the passwords automatically, it works with: - <path-password> - <logon-interrupt-password> To get the clear text password, just do: --8<---------------cut here---------------start------------->8--- python wpkg-pass.py -c '<ciphered text>' --8<---------------cut here---------------end--------------->8--- -- Daniel Dehennin RAIP de l'Orne
