Hi all, I would like to start a discussion on how to implement - https://issues.jboss.org/browse/KEYCLOAK-1900 I have a django web app and all of my users are in a postgres database with salted passwords hashed using SHA. I have been reading how I can use UserFederation to implement by own credential validation, but the drawback here would be that I'll have to keep maintaining my old database. For starters, I was thinking of replacing all occurrences of Pbkdf2PasswordEncoder with an equivalent SHAPasswordEncoder, which is a very crude approach and I'm not sure if it will even work. After some bit of reading I saw this ticket - https://issues.jboss.org/browse/KEYCLOAK-1900 I would like to implement a custom hashing SPI and would love to get some pointers on how to go about it.
