Migrating Passwords From Keycloak To Django

[dev-aakash1998]

Hi, I saw your code pertaining to credential migration from django to keycloak.
I have a use-case where I want Django Users and Keycloak Users to be synced both ways
So now I am designing an Interface which queries Keycloak DB directly for the credentials and inserts into Django Auth User Model. I referred to your code in services/users.py

def credential_representation_from_hash(hash_, temporary=False):
    algorithm, hashIterations, salt, hashedSaltedValue = hash_.split('$')

    return {
        'type': 'password',
        'hashedSaltedValue': hashedSaltedValue,
        'algorithm': algorithm.replace('_', '-'),
        'hashIterations': int(hashIterations),
        'salt': base64.b64encode(salt.encode()).decode('ascii').strip(),
        'temporary': temporary
    }

I tried to backtrack for syncing user credentials from keycloak to django, my credential looks something like this

{"value":"GnDj7oVoD+/YW00wtQXEwZWCXr+O4FSbUpy8T+CjVK53NDfRXS5NHafDm0Rjgo+ttkerhn1Gtokyt+sEEq7TfA==","salt":"F9v+ZT4T9dQMLtuThTqqZQ==","additionalParameters":{}} 

I have tried using the original salt, I also tried to encode the salt and then insert it, but in both cases I get wrong password from django

In [20]: salt2 = 'F9v+ZT4T9dQMLtuThTqqZQ=='                                                                                                                                                                                                   

In [21]: b64encode(salt2.encode()).decode('ascii').strip()                                                                                                                                                                                    
Out[21]: 'Rjl2K1pUNFQ5ZFFNTHR1VGhUcXFaUT09'

The password field in my Django DB looks something like this

pbkdf2_sha265$27500$Rjl2K1pUNFQ5ZFFNTHR1VGhUcXFaUT09$GnDj7oVoD+/YW00wtQXEwZWCXr+O4FSbUpy8T+CjVK53NDfRXS5NHafDm0Rjgo+ttkerhn1Gtokyt+sEEq7TfA==

What am I doing wrong here? Does Keycloak Use some other logic to encode its salt? If yes, then how should I tackle it?
Any help will be appreciated.
