| 3 | |
| 4 | This module implements an interface to the crypt({\bf 3}) routine, |
| 5 | which is a one-way hash function based upon a modified DES algorithm; |
| 6 | see the Unix man page for further details. Possible uses include |
| 7 | allowing Python scripts to accept typed passwords from the user, or |
| 8 | attempting to crack Unix passwords with a dictionary. |

| 13 | \var{word} will usually be a user's password. \var{salt} is a |
| 14 | 2-character string which will be used to select one of 4096 variations |
| 15 | of DES. The characters in \var{salt} must be either \code{.}, |
| 16 | \code{/}, or an alphanumeric character. Returns the hashed password |
| 17 | as a string, which will be composed of characters from the same |
| 18 | alphabet as the salt. |
