openssl s_client using a proxy

Question

openssl s_client -connect some.https.server:443 -showcerts

is a nice command to run when you want to inspect the server's certificates and its certificate chain.

Is there a way to run this command when you are behind a HTTP/HTTPS proxy ?

Answer 1

Officially not.

But here's a patch: http://rt.openssl.org/Ticket/Display.html?id=2651&user=guest&pass=guest
