Where OpenSSL is installed?
By default, after installation, OpenSSL is only available from the directory where it resides (C:\Program Files\OpenSSL-Win64\bin). This means that if you try to use OpenSSL from the command line (command prompt) in any other directory than the above, the command will not be recognized and won't work.

OpenSSL is an open-source command line tool that is commonly used to generate private keys, create CSRs, install your SSL/TLS certificate, and identify certificate information.
- In the command line, enter openssl s_client -connect <hostname> : <port> . This opens an SSL connection to the specified hostname and port and prints the SSL certificate.
- Check the availability of the domain from the connection results.
As I understood LibreSSL is a fork of OpenSSL: LibreSSL is a version of the TLS/crypto stack forked from OpenSSL in 2014, with goals of modernizing the codebase, improving security, and applying best practice development processes.
OpenSSL command is the easiest way to check TLS version. The following commands can be used to find TLS version: openssl s_client -connect host.com:443 -tls1. openssl s_client -connect host.com:443 -tls1_1.
(PuTTY is an SSH client; it doesn't even use SSL/TLS and it does not support X. 509 ("SSL") certificates. The only thing they have in common is private keys – it so happens that OpenSSH uses the same RSA key format (PKCS#1) as OpenSSL does, so that's what you get from PuTTYgen's "Export OpenSSH key" too.
OpenSSL is the programming library used to implement TLS, i.e. the actual encryption and authentication. Whereas your "secure SSL" is just the certificate you install at the server.
