P-256

Overview#

P-256 (also seen as: Secp256r1 prime256v1 1.2.840.10045.3.1.7) is a Elliptic Curve Digital Signature Algorithm using a 256-bit prime field Weierstrass elliptic function Elliptic Curve.

A randomly generated curve. SEC2v1 states 'E was chosen verifiably at random as specified in ANSI X9.62 1 from the seed'.

P-256 is used in WebAuthN (U2F), and CBOR

The Digital Signature Standard defines Elliptic Curve P-256:
