%description
JA4Sentinel is a Go-based tool for capturing network traffic on Linux servers,
extracting client-side TLS handshakes, generating JA4 signatures, enriching
with IP/TCP metadata, and logging results to configurable outputs.

Features:
- Network packet capture with BPF filters
- TLS ClientHello extraction
- JA4/JA3 fingerprint generation
- IP/TCP metadata enrichment
- Multiple output formats (stdout, file, UNIX socket)
- Structured JSON logging for systemd/journald
- Compatible with Rocky Linux, RHEL, CentOS
