Elliptic Curve arithmetic operations written in Noir

elliptic-curve-noir

elliptic-curve-noir is an open source implementation of Elliptic Curve arithmetic operations written in noir.

It contains 1 Noir library

1. EllipticCurve.nr: provides main elliptic curve operations in affine and Jacobian coordinates.

This library provides functions for:

• Modular
  • inverse
  • exponentiation
• Jacobian coordinates
  • addition
  • double
  • multiplication
• Affine coordinates
  • inverse
  • addition
  • subtraction
  • multiplication
• Auxiliary
  • conversion to affine coordinates
  • derive coordinate Y from compressed EC point
  • check if EC point is on curve

Supported curves

The elliptic-curve-noir contract has been extensively tested for the following curves:

• secp256k1
• secp224k1
• secp192k1
• secp256r1 (aka P256)
• secp192r1 (aka P192)
• secp224r1 (aka P224)
