Certicom/RIM/Blackberry has spread a great deal of FUD in its IRP claims; it harms the crypto community when people parrot it, and makes it even worse when they parrot it badly. > and at least two of these, P256 and P384, have p = 3 mod 4.

Just to be clear: you also have no idea what impact the Certicom patents have on any family of curves. None of us do. > RFC 6090 outlines elliptic curve technology which predates the Certicom > patents. Correct. It would have been *way* better to leave out the rest of that paragraph. --Paul Hoffman
