A password_pepper feature has been added. This allows you to use a secret key (called a pepper) to append to passwords before hashing and hash checking. Using this approach, if an attacker obtains the password hash, it is unusable for cracking unless they can also get access to the pepper.
The password_pepper feature also supports a list of previous peppers that can be used to implement secret rotation and to support compatibility with unpeppered passwords.
Rodauthby default uses database functions for password hash checking on PostgreSQL, MySQL, and Microsoft SQL Server, which in general provides more security than a password pepper, but both approaches can be used simultaneously.
A session_key_prefix configuration method has been added for prefixing the values of all default session keys. This can be useful if you are using multiple
Rodauthconfigurations in the same application and want to make sure the session keys for the separate configurations do not overlap.
