Spring security password hash + salt
I am working with a legacy application that stored passwords in plaintext. I have ported the application to spring 3 mvc + security. I have also successfully gotten spring security handling the authentication and authorization using sha256 + a salt based on the username. This all works great, however as part of the deployment, I will need to migrate the existing database to use the new password schema. I am not sure how spring security does it's password hashing with a salt, so i am unable to write a sql script that can be used to migrate the old plaintext passwords to the new sha256+salt
