By default, OpenSSL for Windows is installed in the following directory: if you have installed Win64 OpenSSL v1.X.X: C:\Program Files\OpenSSL-Win64\ if you have installed Win32 OpenSSL v1.X.X: C:\Program Files (x86)\OpenSSL-Win32\ To launch OpenSSL, open a command prompt with administrator rights You can use the same openssl for that. To connect to a remote host and retrieve the public key of the SSL certificate, use the following command. $ openssl s_client -showcerts -connect ma.ttias.be:443. This will connect to the host ma.ttias.be on port 443 and show the certificate. It's output looks like this In this case you would need to set the %PATH% environment variable to c:\OpenSSL-Win32\bin\ that locate the openssl.exe. The other way is to invoke the openssl command by providing the absolute path c:\OpenSSL-Win32\bin\ in the command line. This way you can solve the issue To work on this aspect, I started to use Openssl and here's the steps to achieve it: Step 1: Get the server certificate. First, make a request to get the server certificate. When using openssl s_client -connect command, this is the stuff between the -----BEGIN CERTIFICATE-----and -----END CERTIFICATE-----.
