JA3 Fingerprint: Definition

A JA3 fingerprint is a hash derived from the way a client sets up a TLS connection, which can identify the software making a request. Because tools and browsers negotiate TLS differently, the fingerprint can reveal automation even when headers look normal. Matching a real browser's TLS behavior helps avoid detection.
