[keycloak-dev] argon2 password hashing

hi, a client has requested the use of the argon2 [1, 2] password hashing scheme. this can easily be added as an external provider. we do however require custom password policies, e.g. memory / parallelism cost as well as salt length. AFAIK there is no way to provide policy extensions using a provider interface? would argon2 be a worthwhile contribution? regards roelof.
