HTTPS/Client-authenticated

HTTPS/Client-authenticated
You are encouraged to solve this task according to the task description, using any language you may know.

Demonstrate how to connect to a web server over HTTPS where that server requires that the client present a certificate to prove who (s)he is. Unlike with the HTTPS request with authentication task, it is not acceptable to perform the authentication by a username/password or a set cookie.

This task is in general useful for use with webservice clients as it offers a high level of assurance that the client is an acceptable counterparty for the server. For example, Amazon Web Services uses this style of authentication.

Tcl

Uses the Tls package. <lang tcl>package require http package require tls

set cert myCert.p12 http::register https 443 [list \

   ::tls::socket -certfile $cert -password getPass]

proc getPass {} {

   return "myPassword";  # Just a noddy example...

}

1. Make a secure authenticated connection

set token [http::geturl https://verysecure.example.com/]

1. Now as for conventional use of the “http” package

set data [http::data $token] http::cleanup $token</lang>
