Credit for this example goes to “ Checking A Remote Certificate Chain With OpenSSL” from langui.sh.
openssl s_client -showcerts -connect www.andunix.net:443
Informations about the used arguments from the OpenSSL man page:

	*  s_client: SSL/TLS client program
	*  -showcerts: display the whole server certificate chain: normally only the server certificate itself is displayed.</description>

Credit for this example goes to “Verifying that a Private Key Matches a Certificate” from the University of Wisconsin Knowledgebase.

To see if a key server.key belongs to the certificate server.crt, they need to have the same “modulus” and “exponent”.
openssl x509 -noout -text -in server.crt
openssl rsa -noout -text -in server.key</description>
