Does anyone have working Perl code for Coinbase Advanced API authentication? It uses json web tokens and 256-bit ECC cryptography. I have been at it for several days now and can get close, but have run into issues I cannot resolve. Tried Crypt::JWT for ES256 when using ActiveState Perl on Windows 10. The Python example that Coinbase provides works in Python 3.8, but I have not successfully translated it to Perl. Thanks!
