FIX: Use max supported version instead of client version

v1.3.1-beta

Release version 1.3.1

FIX: JA4 ALPN implementation

This minor version update fixes the incorrectly implmented ALPN section of the generated JA4 fingerprint.

Previously, the first two characters of the first value of the ALPN extension were added to the fingerprint.
Now, the first and last character of the first value of the ALPN extension are added to the fingerprint.

FIX: ALPN NULL logging bug

v1.2.1-beta

ALPN NULL logging bug

JA4one update

Removes tracking of the padding extension

JA4one

JA4one is a new fingerprint that ignores the TLSv1.3 pre shared key extension to reduce the entropy of fingerprints such that any given client (Chrome, Edge, etc.) will map to a single JA4one fingerprint.

JA4 Nginx Beta Release

This is the first official beta release of the JA4 suite on Nginx.

The module adds two Nginx variables that can be used in .conf files:

$http_ssl_ja4
$http_ssl_ja4_string

The values are calculated in real time on a per request basis.
