"""md5crypt.py - Provides interoperable MD5-based crypt() function |
|

||
42 |
SYNOPSIS |
|
43 |
||
44 |
import md5crypt.py |
|
45 |
||
46 |
cryptedpassword = md5crypt.md5crypt(password, salt); |
|
47 |
||
48 |
DESCRIPTION |
|
49 |
||
50 |
unix_md5_crypt() provides a crypt()-compatible interface to the |
|
51 |
rather new MD5-based crypt() function found in modern operating systems. |
|
52 |
It's based on the implementation found on FreeBSD 2.2.[56]-RELEASE and |
|
53 |
contains the following license in it: |
