I wrote a self-defined OpenSSL engine and engine tester in ubuntu 20.4. And the OpenSSL version is 1.1.1. The goal is to use engine in TLS session, and the first step is to use command line to sign a digest. The reference website is: https://wiki.openssl.org/index.php/Creating_an_OpenSSL_Engine_to_use_indigen…
