Please add ECDSA support for iCloud server-server auth

[benspratling4]

Apple's docs for iCloud server-to-server auth require the use of a "ECDSA signature". Please add this capability.

There's another framework that I'm working on that will do what you want. It's just not ready yet. I've still got to add Linux support to it. I'll leave this issue open until it's released and then let you know.

Take a look at BlueRSA. That framework should have what you’re looking for. Reopen (or open an issue against BlueRSA) if it doesn’t suit your needs.
