Will we be able to use a function like openssl_ecdh_compute_key() for elliptic curve diffie-hellman key exchange. We have openssl_dh_compute_key() for RSA but don't have similar function for ECC.

So looking at the code, it should should probably work with OpenSSL 3.0 and PHP 8.1. I will keep this open as it might be worth to port it on lower OpenSSL versions and also cover it better by tests.

The current state is now documented[1], so if we backport, we
should not forget to update the documentation.
