Hi sage, At a quick look at the ceph codebase, the cryptographic handshake is handled by the Pipe class(I might be wrong), it not using the openssl handshake and not using the openssl crypto library. I am wondering when we encrypt the actual data, are we going to implement our own encrypt functions? I am familar with Openssl, I am still a little confused about the project(mostly if I can use openssl to encrypt the on wire data). It would nice if you could explain it a little more.
