OpenSSL Linux command line ssl tool

Verify a web server certificate

  • openssl s_client -showcerts -connect my.test.com:443
    • Output should end on "Verify return code: 0 (ok)"
    • As of 2017 the TLS Protocol should be TLSv1.2 at least.
  • For sni you can add -servername xyz.test.com

OpenSSL retrieve url

  • retrieve url, e.g. /healthz, note -ign_eof to wait for more input from echo

    time echo -e "GET /healthz HTTP/1.1\r\nConnection: close\r\nHost: pieter\r\n\r\n" | openssl s_client -ign_eof  -connect 172.24.0.3:443
