I am new to HTTPS/SSL.
I need to write a HTTPS client which will reject all the connection by saying unknown CA . As I understand (through wireshark capture) during SSL connection, first client will send the ‘client hello’ message. In reply to this server will send message with three record – ‘server hello’, certificate, ‘server hello done’.

What I am trying to achieve here is when the server will send certificate, client should always reject it.

I am trying to achieve it with following code but no luck.

How can I get LWP to validate SSL server certificates?

It’s ok if solution is in some other language.

    It should be enough to do the connection with no (or dummy) CA certificates known to the client. Have you tried setting SSL_ca_path and SSL_ca_file to dummy values?

    Edit:

    If any language goes, why not try openssls s_client?

    openssl s_client -connect www.stackoverflow.com:443
