Following the recent spate of hacks using the security vulnerbility in all Joomla 1.5.x versions prior to 1.5.6 I have had a need to generate new password hashes for manual inputting into the Joomla jos_user database table
If you have no idea what this is or why you need it then this tool is not intended for you 
Ignoire it
You can access the tool securely at
– https://secure.phil-taylor.com/generate_password.php
This tool generates an md5 salted hash, the salt is dynamica and changes each time meaning the encrypting of a password will (in theory) not generate the same hash twice.
Enjoy!
hmm can I seet the source ,I have some problems with my joomla paswords .. so is it possible to send me the source?
The source can be viewed here:
https://secure.phil-taylor.com/generate_password.phps
Its nothing special, and is actually copied from Joomla itself.
Kindest regards
Phil.
Tnx a lot , i need for making a login box in c# so i had problems with md5 now i think it will be ok ..
thanks again
Hi Phil,
I just modified the function you wrote for my own needs to produce a generic batch update of passwords in jos_user.
Are you happy for me to publish my script and credit you?
Cheers!
