Is there an existing issue for this?

  • I have searched the existing issues.

Describe the solution you'd like

Can you please implement JA4 TLS fingerprinting as it would significantly enhance Sniffnet’s ability to analyze encrypted traffic by exposing behavioral patterns in TLS handshakes even when payloads are encrypted.

This is an existing project that could be used to generate the fingerprints: https://github.com/biandratti/huginn-net

JSON list of known fingerprints: curl -s "https://ja4db.com/api/read/" | jq '[.[] | select(.application != null)]'

Main JA4 repository: https://github.com/FoxIO-LLC/ja4
