This module implements an interface to the crypt(\strong{3}) routine,
1996-04-10 13:18:20 -03:00
which is a one-way hash function based upon a modified DES algorithm;
see the \UNIX{} man page for further details. Possible uses include
1996-04-10 13:18:20 -03:00
allowing Python scripts to accept typed passwords from the user, or
attempting to crack \UNIX{} passwords with a dictionary.

\begin{funcdesc}{crypt}{word\, salt}
\var{word} will usually be a user's password. \var{salt} is a
2-character string which will be used to select one of 4096 variations
of DES. The characters in \var{salt} must be either \code{.},
\code{/}, or an alphanumeric character. Returns the hashed password
as a string, which will be composed of characters from the same
alphabet as the salt.
\end{funcdesc}
The module and documentation were written by Steve Majewski.
