[jira] [Comment Edited] (CASSANDRA-14223) Provide ability to do custom certificate validations (e.g. hostname validation, certificate revocation checks)

My request is to be able to apply ANY form of customized certificate validation, which OCSP is just one example. For example, an application I am working on allows the user to administer what types of validation one would like to apply (e.g. OCSP, CRLS, Host Name Validation, etc.).

In respect to OCSP, one could provide a customized Trust Manager that would have the intelligence to know whether or not to apply OCSP checking and to what degree (i.e. SOFT_FAIL=true or false). The benefit being that the customized Trust Manager could do this without having to reconfigure and restart Cassandra. Additionally, the custom Trust Manager could also determine whether or not to provide CRL validation, hostname validation, etc.

I have found and tested that this capability can be added to Cassandra today in a very general way through some minor code changes and the use of customized SSLSocketFactory and SSLServerSocketFactory:
 1) The customized SSLSocketFactory and SSLServerSocketFactory instantiate and initialize an SSLContext  with a customized Trust Manager and set this  and are specified in a java.security properties file.
 2) Cassandra could make use of this intelligent SSLContext by a minor modification in SSLFactory::createSSLContext(). 
 For example:
 SSLFactory::(createSSLContext():

        try
         {
          if (Security.getProperty("ssl.SocketFactory.provider") != null
          || Security.getProperty("ssl.ServerSocketFactory.provider") != null)

{                 // use default SSLContext created in the socket factories                 ctx = SSLContext.getDefault();          }

else {
                 // use Cassandra provided SSLContext (same as before)
                 ctx = SSLContext.getInstance(options.protocol);

...

> 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.
