What is Noise? The Noise Explorer command-line tool can parse Noise Handshake Patterns according to the original specification. It can generate cryptographic models for formal verification, including security queries, top-level processes and malicious principals, for testing against an active or passive attacker. Noise Explorer can also generate fully functional discrete implementations for any Noise Handshake Pattern, written in the Go and Rust programming languages, as well as WebAssembly binaries.
