client rejecting server certificate

Question

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.

Answer 1

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 openssl s s_client ?

openssl s_client -connect www.stackoverflow.com:443
