huginn-net

Huginn Net is a passive traffic fingerprinting tool that analyzes TCP, HTTP, and TLS protocols without active probing, providing insights into operating systems, applications, network infrastructure, and client capabilities. Built in pure Rust, it utilizes open-source specifications such as p0f for TCP and JA4 for TLS, allowing for community-driven signature databases. Notable features include support for HTTP/1 and HTTP/2 fingerprinting, OS type and version identification, and detailed analysis of TLS handshakes and TCP signatures.
