pub struct Secp256k1;
Available on crate features
ecdsa
and secp256k1
only.Expand description
secp256k1 (K-256) elliptic curve.
Specified in Certicom’s SECG in “SEC 2: Recommended Elliptic Curve Domain Parameters”:
https://www.secg.org/sec2-v2.pdf
The curve’s equation is y² = x³ + 7
over a ~256-bit prime field.
It’s primarily notable for usage in Bitcoin and other cryptocurrencies, particularly in conjunction with the Elliptic Curve Digital Signature Algorithm (ECDSA).
