I seen many posts about how to integrate phpBB in your external website.
For this there is a requirement of the ' PasswordHash.php ' files that are found all over the forums..
but i will include this below here
PasswordHash.php
Code: Select all
<?php
#
# Portable PHP password hashing framework.
#
# Version 0.1 / genuine.
#
# Written by Solar Designer <solar at openwall.com> in 2004-2006 and placed in
# the public domain.
#
# There's absolutely no warranty.
#
# The homepage URL for this framework is:
#
# http://www.openwall.com/phpass/
#
# Please be sure to update the Version line if you edit this file in any way.
# It is suggested that you leave the main version number intact, but indicate
# your project name (after the slash) and add your own revision information.
#
# Please do not change the "private" password hashing method implemented in
# here, thereby making your hashes incompatible. However, if you must, please
# change the hash type identifier (the "$P$") to something different.
#
# Obviously, since this code is in the public domain, the above are not
# requirements (there can be none), but merely suggestions.

This is only a basic example.
But for every programmer out there...
Enjoy
Because this should be enough to get you all started on your own external portal system.
