Customizing TLS (JA3) Fingerprints through HTTP Proxy
JA3Proxy is a tool designed to customize TLS (JA3) fingerprints through an HTTP proxy. It allows users to modify their TLS client fingerprint by selecting predefined or custom configurations, enabling enhanced privacy, testing, and research capabilities.
Key Features:
Supports predefined clients and versions for popular browsers and frameworks (e.g., Firefox, Chrome, Safari, Edge).
Allows customization of TLS fingerprints to simulate different browsers or versions.
Configurable to use upstream proxies for chaining connections.
Flexible configuration options for certificates and keys.
Easy integration via command-line interface or Docker container.
Audience & Benefit:
Ideal for developers, cybersecurity professionals, privacy advocates, and researchers who need to test web applications' fingerprinting mechanisms, bypass geolocation restrictions, or enhance privacy by masking browser identification. JA3Proxy provides a robust solution for TLS fingerprint manipulation, enabling users to control how their connections are perceived online.
JA3Proxy can be installed via winget for easy setup on Windows systems.
