WhizMQ - A message queue library implementing ZMTP 3.0 in Nim.
Built on top of PowPow event library

nimble install whiz

API reference

😍 Key Features

• ZMTP 3.0 wire protocol, full greeting, framing, and command handling
• Socket patterns: PAIR, PUB/SUB, REQ/REP, PUSH/PULL, File Transfer
• Security mechanisms:
  • NULL: no authentication (plaintext)
  • PLAIN: username/password authentication with ZAP callback
  • CURVE: X25519 + XChaCha20-Poly1305 AEAD encryption and mutual authentication
• Transport TCP and IPC (Unix domain sockets)
• Built on PowPow event notification library in Nim

Note

CURVE requires Monocypher (via the e2ee package). Install it with your system package manager (brew install monocypher, apt install libmonocypher-dev, etc.) or build from source.

🗺 Roadmap

• ZMTP 3.0 wire protocol (greeting, framing, commands)
• PAIR, PUB/SUB, REQ/REP, PUSH/PULL socket patterns
• File transfer over ZMTP
• PLAIN security mechanism + ZAP auth callbacks
• CURVE security mechanism (X25519 + AEAD)
• RADIO/DISH (dgram) socket pattern
• CLIENT/SERVER (stream) socket pattern
• CURVE vouch (Ed25519 signature in HELLO for key continuity)
• TLS/DTLS transport
• GSSAPI / Kerberos mechanism
• WebSocket transport (RFC 7692)
• Formal ZMTP conformance tests
• Performance benchmarks vs ØMQ
