How to use OpenSSL command line to operate(signature, for example) after loading OpenSSL engine?

cryptography dsa linux openssl openssl-engine

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_indigenous_ECDH_ECDSA_and_HASH_Algorithms But the tester use the engine by calling the function, like ECDSA_sign and ECDSA_verify in

Using MD5 in kernel space of Linux

c++ cryptography linux

I am trying to use the kernel space implementation of the md5 algorithm (md5.h and md5.c). It turns out that md5.h does not declare the functions found in md5.c, so I could not simply include md5.h into my c file. I also wanted to avoid altering md5.h to declare the functions, since that could have unintended consequences. Is there any

Code Signing for Linux

Are there any providers offering code signing certificates for (Red Hat Enterprise) Linux? I see a lot of buzz for Microsoft-land, but not much for Linux. I know how to generate my own certificates and embed a public certificate into my executable. I’m specifically looking for ways to get the certificate signed by a trusted CA. The target system is
