title: Authlogic: How to prevent reuse of previous password?
body: <p>how can you find out the user's past encrypted password to check if he is using the old password as the new one, in previous &quot;Authlogic&quot; versions it was easy to check, but in newer versions, I cannot find out the password hash, even if I know the old salt and the new password, is there a way to determine if the user is using the old password as the new one?</p>
