WS-Security on iphone, is it possible?

I'm new here and I'm facing a problem. I need to know if it is possible to implement the WS-Security protocol with X.509 certificates on a native iPhone application. I haven't found much information on the web, except this information from Apple about security services.

I just want to ask, is it possible? has it been made before?. If it is possible, can you point me in the right direction开发者_开发技巧?.

Thanks in advance.

You should be able to implement this using OpenSSL.

There is a tutorial on The Rare AiR on how you can compile the library for iPhone.

Hope this helps, Claus
