CAMNET server, and its Windows clients, connect using Windows Schannel (TLS 1.x) by default. This connection is further encrypted, just in case some bad guy has broken your SSL, with a one-time encryption key exchanged using the Secure Remote Password (SRP) prototcol.

This is the cipher info used by CAMNET server with a connected Windows client, as seen in the event viewer with loglevel.txt set to 128:

   SSL channel cipher info:
   TLS 1.2
   TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384_P256
   AES-256  block length: 16 bytes
   SHA384 384 bits
   ECDH_P256 RSA TLS_ECC_P256_CURVE_KEY_TYPE
