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

Invoke-WebRequest Always Fails For HTTPS. The remote certificate is invalid according to the validation procedure
I’m trying to use Invoke-WebRequest inside of pwsh (on Linux), but it’s always failing. Here’s an example: The site/URL doesn’t matter, if it’s using HTTPS I’ll get the error.

How to use OpenSSL for self-signed certificates with custom CA and proper SAN settings?
I run across this topic once in a while, trying to remember how this was done then find all the incomplete answers again (with config files, oneliners,ignoring that we really want to use a custom CA to create a full certificate chain etc.). And many answers applying SAN for the certificate request, but messing SAN up in the signing command…

Building Poco with Custom OpenSSL
I need to build Poco using the OpenSSL that I built from source, rather than the one installed by Ubuntu’s apt. Let’s say my OpenSSL root is in /opt/openssl/1.0.2. Do I need to set environment variables, or pass parameters to the configure or make steps? I’m not finding any info in the docs, or anywhere else, on how to do
Upgrade openssl on Linode server but how to decide ‘ENGINESDIR’
On Linode Server, it has already installed openssl, but version is 1.1.0. But I want to try some features like TLSv1_3, so I decide to upgrade it to latest version. My old openssl version like this: Due to it is “upgrade”, so I try to retain as original as possible. Through some website I made this ./config command. It’s long,
Is there a way to convert stdin/stdout fds into one fd?
I want to process SSL from stdin, and send SSL out stdout, but OpenSSL accepts only one file descriptor in the set fd call: Is there a way to combine the stdin and stdout file descriptors into one? I realize I can make a process that just reads from stdin/out and writes to the file descriptor, but I was trying

I was compiling some ‘C’ code that uses openssl under Fedora 27 (version 1.1.0g-1). I made some needed changes (from the 1.0.2 version of my code) and things now compile o.k. again. I then tried to compile with the option “OPENSSL_API_COMPAT=0x10100000L” which I understand causes the compiler to not include APIs deprecated in openssl version 1.1. Now, my code won’t
