Brian, there is no TLS or root CA certificates on this platform. No browser. No X11. No screen or keyboard for that matter.

Thanks. As I note, that is a non-trivial project/barrier. FWIW, I'm putting together a generic service for this application, where a user can oAuth to the site and then create proxy credentials that can be used to tweet etc. http://www.supertweet.net/ Feedback welcome.

Hi Glenn, FWIW, the application and platform is extremely small and lightweight - there is nothing as powerful or huge as 'curl' there. It is all raw C code, stripped down libraries, etc. measured in K-bytes, not Megabytes, to say nothing of Gigabytes. For example, the current 'tweet' code binary is 18K bytes. If you can add oAuth in 100K bytes or less, that might work, but that one function would then still be bigger than the entire rest of the application. In fact, the entire file system ROM image, with all the binaries and data is 114K bytes.
