Overview#

CurveZMQ is an adaptation of the CurveCP protocol for TCP

• CurveZMQ uses the same high-speed Elliptic Curve cryptography that CurveCP uses and adopts the initial CurveCP "handshake" mechanism of initial key exchange.
  
• CurveZMQ uses the Curve25519 (X25519) elliptic curve and to achieve good performance with short key sizes (256 bits).
• CurveZMQ protocol establishes short-term Session Keys for every connection to achieve Perfect Forward Secrecy. Session Keys are held in memory and destroyed when the connection is closed.

Combined with minor changes to adapt CurveCP for a connected and message-based use provides much of the security benefit of CurveCP in a more traditional flavor that is compatible with the ubiquitous TCP protocol.
