> NSA: Use our curves. They were selected randomly. Promise, wink wink.

Here's a better explanation about this cryptic tweet:

Backdoors in NIST elliptic curves

Of particular concern are the NIST standard elliptic curves. There is a concern that these were some-how “cooked” to facilitate an NSA backdoor into elliptic curve cryptography. The suspicion is that while the vast majority of elliptic curves are secure, these ones were deliberately chosen as having a mathematical weakness known only to the NSA.
