I'm adding HTTPS support to an embedded Linux device. I have tried to generate a self-signed certificate with these steps: openssl req -new > cert.csr openssl rsa -in privkey.pem -out key.pem op...
As of OpenSSL 1.1.1, providing subjectAltName directly on command line becomes much easier, with the introduction of the -addext flag to openssl req (via this commit). The commit adds an example to the openssl req man page: Example of giving the most common attributes (subject and extensions) on the command line: openssl req -new -subj "/C=GB ...
20 The problem is, that openssl -verify does not do the job. As Priyadi mentioned, openssl -verify stops at the first self signed certificate, hence you do not really verify the chain, as often the intermediate cert is self-signed.

I'm trying to generate OpenSSL certificates on Windows OS. But I find most of the commands related to OpenSSL are for *nix OS. Is there an OpenSSL for Windows OS? If yes, from where can I get it?...
Most software linking OpenSSL have tickets where they introduce support for the new openssl behaviour, e.g. 1, 2, 3. Currently, in Ubuntu 22.04 LTS curl is version 7.81.0, and fails in case of unexpected EOF with OpenSSL 3.0.x. The latest curl is 7.88.1, and apparently resolved the issue, though I could not find the exact commit or ticket.
openssl s_client -servername example.com -connect example.com:443 \ /dev/null | openssl x509 -text The -servername option is to enable SNI support and the openssl x509 -text prints the certificate in human readable format.MSN: OpenSSL 3 performance issues causing a scalability and security dilemma for organizations
