Extract A Server Certificate From A HTTPS Connection.

  • submit to reddit
        You can simply extract information about the SSL certificate of HTTP connections using OpenSSL

openssl s_client -connect ${URL}:${PORT}

For example:

openssl s_client -connect

From there, it is only redirecting the output to a file or extracting information out of the stream with Perl.
