| |
| This module implements an interface to the \manpage{crypt}{3} routine, |
| which is a one-way hash function based upon a modified DES algorithm; |
| see the \UNIX{} man page for further details. Possible uses include |
| 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\indexii{cipher}{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} |
