Can someone translate this into English?
I can't translate the crypto (I have only a vague understanding of what the elliptical stuff is about), so the best I can do is say, the guys in Redmond came up with some much-improved algorithms for encryption, faster and better than what presently exists, and they're making it available to the public for examination, critique, and use.
It's news not just because of the technology, but also because this is something Microsoft historically has not done often. They usually keep things for themselves, proprietarily, but if they did that with some new encryption scheme, nobody would trust it. So they sorta have to play open with it.
But I don't care what their internal motivation is -- I'm just pleased they're making it available.
