SOAP calls with Client Certificates


Level 1
I am trying to access a site which is protected by SSL. They
require client certificates, as part of the authentication process.
I can't seem to find any documentation on working with client
certs, everything seems to be about adding client cert support to
Cold Fusion. But, I need it when I make a SOAP call from Flex. Can
anyone help me?

Thanks in Advance,

David, I am interested in connecting to a web server which
requires X.509 client certificates. Have you found a way to use the
HTTPService within flex to accomplish this? I can't find
documentation on how to do this (or if it is supported). Sorry not
an answer - thanks for any help.

Alas, it's not to be. Flex's SOAP implementation uses the
browser's HTTP stack, which means you need to set up client certs
via the browser. If that works for you, then it's relatively easy.
Just point your browser to the .p12 file, and it'll walk you
through the process. For me, this wouldn't work, since I was making
an app for general internet usage and I didn't want to have to have
all my users install the client certs.

Instead, I made a SSL proxy on a hosted server, and gave it
my client cert. It's a little kludgy and not the fastest thing in
the world, but it works relatively reliably.

Dave, thanks so much for your response. This has been a big
help. The browser works fine for what I am doing - it makes sense
that they use the browser's http stack. It's simple, I had thought
it would be more complicated. Hopefully, this will help others who
are asking the question on "How to use client certificates in
flex". Your proxy implementation is also great information.

Hello, I have some problem using client certificates with
flex. If the webservice hosted on IIS is set to accept client
certificates all works well, if I set it to require client
certificates I receive a generic error:"unable to load wsdl". I can
access the webservice trough the browser, without any problem using
the client certificate .

Any ideas?
