I'll preface the post by saying I'm aware of the TLS problems browsers face on OS 9.
I'm curious if there are any libraries for OS 9 which support HTTP + TLS 1.3? Modern websites are less and less suitable for browsing on these old systems, but these days it is pretty common for useful Internet services to provide a HTTP API.
It seems like with decent HTTPS JSON libraries you could build little custom programs to access individual services, such as the Internet Archive, that would avoid the pain of trying to interact with the modern web via increasingly dated browsers. However, because these APIs often require a token for authentication, modern TLS support would be important.
