Password format in database

Hi,

I mentioned the password format in the database is bcrypt in 2y format ?

However, checking the password hash using a PHP-function and some online tools, all fail because of invalid salt. The hints, changing 2y or 2b to 2a or 2b or 2y, they all do not work.

So, it is not bcrypt, or it is addtionally a SHA256 over it?

Thanks
Ronny
