[keycloak-user] Proposal: More Secure PassowrdHashProviders

[Bruno Oliveira]

Hi Adam and John, I understand your concern. Although, collisions are not
practical for key derivation functions. There's a long discussion about
this subject here[1].

Anyways, you can file a Jira as a feature request. If you feel like you
would like to attach a PR, better.
