RE: Netscape Ldap ldif file SHA password cracking

[Bénoni MARTIN <Benoni.MARTIN () libertis ga>]

Hi !

In that case, you have also such a tool coming with Apache distrib, tool called htpass or htaccess (think it's the 
first proposal). It allows you to encrypt with MD 5 or SHA.

  I did some googling around and found this 

   http://tinyurl.com/6vyw8

   From that page 

  [...]

   SOFTWARE 
   'pwdhash' is a command-line program to generate or check userPasswordvalues. This program is 
   included with Netscape Directory Server; you'll find it in NSHOME/bin/slapd/server. For example, 
    to digest passwords: 

% cd $NSHOME/bin/slapd/server
% ./pwdhash -s SHA abc abcdbcdecdefdefgefghfghighijhijkijkljklmklmnlmnomnopnopq
{SHA}qZk+NkcGgWq6PiVxeFDCbJzQ2J0=
{SHA}hJg+RBw70m66rkqh+VEp5eVGcPE=

Or, to check passwords: 

% ./pwdhash -c '{SHA}qZk+NkcGgWq6PiVxeFDCbJzQ2J0=' abc
./pwdhash: password ok.
% echo $status
0
% ./pwdhash -c '{SHA}QZk+NkcGgWq6PiVxeFDCbJzQ2J0=' abc
./pwdhash: password does not match.
% echo $status
1

  [...]

   Thou i haven't tested this, I think it would be easy enough to write a small BF script in conjuction with 
   'pwdhash -c' and a wordlist. It may not be a totaly practical solution to your problem
   but, may get you to where you need to go.  ;) 

  
Just my 2 cents.
