A tale of two elliptic curves

A few days ago I blogged about the elliptic curve¬†secp256k1 and its use in Bitcoin. This curve has a sibling, secp256r1. Note the “r” in the penultimate position rather than a “k”. Both are defined in SEC 2: Recommended Elliptic Curve Domain Parameters. Both are elliptic curves over a field zp where p is a … Continue reading A tale of two elliptic curves
