|
This module implements an interface to the crypt({\bf 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. 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}
