Ron Blechman commented on CASSANDRA-14223:
------------------------------------------
I haven't tried this on the 4.0 trunk.
I have been working solely with Cassandra 3.11.2. and have been testing this
with CRLs that are pre-fetched - which I believe avoids the concerns you
mentioned about blocking. My comments about OCSP are looking more towards the
future - as my first priority is to have this work with CRLs. I have tested
this with OCSP and dynamically downloaded CRLS, but perhaps not rigorously
enough to run into the issues you expressed concern about.
> Provide ability to do custom certificate validations (e.g. hostname
> validation, certificate revocation checks)

> URL: https://issues.apache.org/jira/browse/CASSANDRA-14223
> Project: Cassandra
> Issue Type: Improvement
> Components: Configuration
> Reporter: Ron Blechman
> Priority: Major
> Labels: security
> Fix For: 4.x

>
> Cassandra server should be to be able do additional certificate validations,
> such as hostname validatation and certificate revocation checking against
> CRLs and/or using OCSP.
> One approach couild be to have SSLFactory use SSLContext.getDefault() instead
> of forcing the creation of a new SSLContext using SSLContext.getInstance().
> Using the default SSLContext would allow a user to plug in their own custom
> SSLSocketFactory via the java.security properties file. The custom
> SSLSocketFactory could create a default SSLContext that was customized to do
> any extra validation such as certificate revocation, host name validation,
> etc.
