Python TLS ALPN handshake

Came across an issue where a certain API has started filtering HTTP/S requests based on the JA3 fingerprint. The deliverable expected here is a Python TLS 1.2/1.3 ALPN handshake solution which has the same JA3 fingerprint as one of the newest firefox/chrome version browsers. This solution must then be integrated so it could be used with higher level python request libraries with support for HTTP proxy connections. Problem description: To initiate a SSL session, a client will send a SSL Client Hello packet following the TCP 3-way handshake. This packet and the way in which it is generated is dependent on packages and methods used when building the client application. This has allowed fingerprinting of client applications online since browsers and HTTPS (SSL) libraries produce very different JA3 fingerprints which makes non browser handshakes stand out. The JA3 is generated based on clients SSL Version, Accepted Ciphers, List of Extensions, Elliptic Curves, and Elliptic Curve Formats so customization of such parameters during ALPN handshake mostly in client Hello message will probably need to be implemented to then replicate the SSL handshake of a browser.

Hello. I am an experienced python developer who can change your JA3 fingerprint while doing API requests to match that of chrome/firefox by changing the SSL and Cipher settings before the request. Please contact me for further discussion.
