Hi all,
Unfortunately, I have a website that I need to change from ADDT to another system and I have to carry on username and passwords.
But I used encrypted passwords with ADDT and now they are unusable on the new system.
So, I need to convert a 1.300+ encrypted password to simple text passwords.
I have the original table and the randomkey.
But how can I convert these passwords?
Is there a way to de-crypt them?
Or have I to reset all passwords and send emails asking to change passwords to all users?
TIA
tony

Not sure how ADDT encrypt the passwords.
So you probably better off just resetting the passwords. You can always use the excuse that you doing a security audit and found most members didn't change their passwords.
