Re: [SILLY QUESTION] Uncrypting passwords

There is no need to decrypt the passwords.  It is proper and accepted
for the imp to create a new temporary password for a forgetful player.
You are opening up a HUGE security problem there.  For example, I
typically use the same passwords for my GOD and my player char.  so if
another IMP got my PC password, he could instantly log on to my

Or, even worse.  I know a lot of people that use the same passwords for
thier MUD char as they do the shell account.  So if someone could get
their password on the MUD, login to the server shell and demolish a
major internet server.

PS:  This is also why it is recommended to dedicate a machine to MUD and
IRC.  Those two services are targets for more hackers than any other

Just a gold coin or two.
