Not actually that hard to do but will require some changes in a couple of the primary files.

/member.php

PHP Code:

if ($user['password']!=md5($password)) {  // check password 


changes to

PHP Code:

if ($user['password']!=crypt($password, substr($password, 0, 2))) {  // check password 


then in /admin/sessions.php

PHP Code:

    if (md5($loginpassword)!=$bbuserinfo[password]) { 


becomes

PHP Code:

if (crypt($loginpassword, substr($loginpassword, 0, 2))!=$bbuserinfo[password]) { 


PHP Code:

$bbpassword=md5($loginpassword); 


becomes

PHP Code:

$bbpassword=crypt($loginpassword, substr($loginpassword, 0, 2)); 


Thats the basics to make it work, you will need to change the lost password function as well.
