Sam Tunnicliffe commented on CASSANDRA-13626:
---------------------------------------------
+1 LGTM.
I pushed some *tiny* additions to {{PasswordAuthenticatorTest}}
[here|https://github.com/beobal/cassandra/commit/fba4d7fcb3630b4ba67833f9e451cf03aa11aa62].
If you think they're overkill, I won't argue too hard.

> Key: CASSANDRA-13626
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13626
> Project: Cassandra
> Issue Type: Bug
> Components: Auth
> Reporter: Jeff Jirsa
> Assignee: Jeff Jirsa
> Priority: Minor
> Fix For: 3.0.x, 3.11.x, 4.x
>
>
> We use {{Bcrypt.checkpw}} in the auth subsystem, but do a reasonably poor job
> of guaranteeing that the hashed password we send to it is really a hashed
> password, and {{checkpw}} does an even worse job of failing nicely. We should
> at least sanity check the hash complies with the expected format prior to
> validating.
