Debug Server Certificate from Client

Credit for this example goes to “ Checking A Remote Certificate Chain With OpenSSL” from langui.sh.

openssl s_client -showcerts -connect www.andunix.org:443
  • s_client: SSL/TLS client program
  • -showcerts: display the whole server certificate chain: normally only the server certificate itself is displayed.
  • -connect www.andunix.org:443: This specifies the host and optional port to connect to. If not specified then an attempt is made to connect to the local host on port 4433.
