Decrypt the password encrypted with the command #encrypt, it is just
a simple protection.
Example:
               #encrypt security
Ytin will show you the string: LY,[CC7ZLIH
Now you can relatively safely store your password in your tintinrc file:
               #var passwd {LY,[CC7ZLIH}
When the MUD ask you for password, u can type (mostly using #action):
               #decrypt $passwd
yTin made some effort to forbid any future use of #decrypt in the same
session later. (note: the effort here is just to forbid others to
know your exact password and/or change your password, if you write your
password into tintinrc file, others can still login using your script
if they got the file.)
