[−][src]Struct signatory::ecdsa::curve::nistp256::NistP256
The NIST P-256 elliptic curve: y² = x³ - 3x + b over a ~256-bit prime field where b is "verifiably random"† constant:
b = 41058363725152142129326129780047268409114441015993725554835256314039467401291
† NOTE: the specific origins of this constant have never been fully disclosed (it is the SHA-1 digest of an inexplicable NSA-selected constant)
NIST P-256 is also known as prime256v1 (ANSI X9.62) and secp256r1 (SECG)
