Re: HTTPS proxy tool that resigns SSL certs

Yeah, but this will still pop up a certificate warning.

I am assuming you are talking about proxy for an *outbound* connection.

This can be done without having the private key, but it gets a little
complicated to setup. This is assuming you have full control of the
client end network - DNS, routing, etc...

Set up your own authortative record in the DNS at the client end of
the connection. Have it redirect to your own site with a validly
signed cert (try to make the name as close as possible so as not to
make it easily noticeable to the end-user). Then make a connection
from your server and pass the results back to the client (with or
without any modification you want to do). Basically you are still
acting as a proxy, but rather than passing SSL traffic directly, you
become and end point to the user and a client point to the legitimate
end point. That way all the information will traverse in plain-text
across the computer, yet still be encrypted everywhere else.
