Andy Tolbert commented on CASSANDRA-18778: ------------------------------------------ My understanding of [CASSANDRA-18124] was that it was oriented towards allowing {{keystore_password}} to be nullable for the {{PEMBasedSslContextFactory}}-based implementation to allow null/empty passwords, which it previously didn't. A side effect of this change was also that the default {{FileBasedSslContextFactory}} was changed to additionally validate the password to ensure it was non-null/empty[1]. This validation did not previously exist, and since {{KeyStore}} does allow empty passwords, this could be a regression for someone upgrading from 4.0 to 4.1.2+ where empty password PKCS12 keystores were used. It's probably not a common use case, but was something I encountered myself during testing.
