Completed HMAC calculation/population/validation. Got socket reading/writing fully working/tested. Updated project.yml to link in OpenSSL libcrypto. Updated Kinetic Ruby test server to use a simple TCPSocket impelementation, since data is not http. Also added read(x) command to test server to 'ask' for data to be sent for socket receive tests.
