Can not build with OpenSSL 3.0 (Used in Ubuntu 22.04 LTS)

Many deprecated functions are used:

https://www.openssl.org/docs/manmaster/man3/PEM_write_bio_EC_PUBKEY.html
https://www.openssl.org/docs/manmaster/man3/EC_KEY_free.html

And a pile more that I gave up copying and pasting

I got this error

There is a lot of refactoring needed to make this library compatible with OpenSSL 3. I've been chipping away at it very slowly. Would like to see some of the pending PRs be accepted before I put any serious time into a larger project such as this.

It also won't compile on Oracle Linux Server release 9.1 + Red Hat Enterprise Linux release 9.1 (Plow)
