User password encryption algorithm

Use old version (7.01)

This is not secure enough... don't even try to use it...

Use 7.01 :)

Not even a combination with base64 and md5?

No... this isn't a hashing algorithm.
Password -> base64_encode -> base64_decode -> Password.
Password -> sha256 -> hash -> ... there's no way back.

You can change the hashing algorithm in the settings table to a different hash algorithm, but sha256 is good enough atm.

I want to use the database with a gameserver that doesn't have all the hashing algorithms..
I only have md5 and base64 available atm.

Can you post more details or a documentation about the server?!
You can set the algorithm with the "password_algorithm" in the settings table, but it is not recommend to change this value!

I don't much about Gaming Servers but you should be able to send the password to the server during the login... or if it has a web frontend you can set the session or cookie to identify the user.

You can add new user-field with new(or original) password [md5] also.

The gameserver comunicates directly with the database, no interaction with the php part.
What about the salt? I need it removed.
I looked in the php class but it's too complicated for me to understand...

It worked with md5 by modifying the settings in the database but in the php class it's twice md5 encryption :D.
Problem solved, thanks.
