Subject: Re: PHP Script to Hash Plain-text input to LM/NTLM

I took another stab at creating hashes from plain-texts and below you
will find the latest
revision. This version spits out Crypt(3), MySql323, MySql-Sha1, MD5,
SHA1 and LM+NTLM.

I'll be posting an online version sometime soon, for now this will be
the last version I send
to the list :) Again I hope it's useful to others, have a good weekend!
