[keycloak-user] Hash Algorithm

[Remi Cartier]

Hey guys,

I will have to migrate from a custom in house user management system to keycloak.
We are using this algorithm to store salted/hashed password :

    public static String hashPassword(String password, String salt) {
        try {
            KeySpec keySpec = new PBEKeySpec(password.toCharArray(), salt.getBytes(), 2048, 160);
            SecretKeyFactory secretKeyFactory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
            byte[] hash = secretKeyFactory.generateSecret(keySpec).getEncoded();
            return new BigInteger(1, hash).toString(16);
        } catch (Exception x) {
            throw new IllegalStateException(x);
        }
    }

I was wondering, in order to ease the migration, if I could configure keycloak to use the same hash algorithm ?

Or if there was any other ways ? Like maybe a federation provider, but then comes the question when to push things into keycloak, at password change ?

What do you think ?

Sincerely.
