Subject Re: Client traffic encryption best practices....

Yes - that ticket was done by Nirmal Ranganathan for the intention of getting support in Cassandra.
 That's just for a java client though.

In the future, I wonder if the CQL driver level is the right place for client encryption.

a bit, but I was wondering if anyone had any experience with this or could suggest something
that might be better.
