Can be used only for educational and testing purposes, but a commercial license is available for the script as well.
It combines encryption and salted hashes to use in authentication.
The procedure's speed can be improved by pre-generating and storing key state tables.It returns encrypted/decrypted data strings.
The procedure can be batched on several databases at once.It closes a security hole where a login potentially can read data from a database they should not have access in the first place.
