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 \character{.}, \character{/}, or an alphanumeric character.
|
|
Returns the hashed password as a string, which will be composed of
|
|
characters from the same alphabet as the salt.
