View Source Tezex.Crypto.Curve (tezex v2.0.0)
Specific elliptic curve data.
Parameters:
:A[non_neg_integer/0]: angular coefficient of x in the curve equation. ex: 123:B[non_neg_integer/0]: linear coefficient of x in the curve equation. ex: 123:P[non_neg_integer/0]: curve modulo. ex: 12345:N[non_neg_integer/0]: curve order. ex: 12345:G[Tezex.Crypto.Point.t/0]: EC Point corresponding to the public key. ex:%Tezex.Crypto.Point{x: 123, y: 456}:name[atom/0]: curve name. ex: :secp256k1
Summary
Functions
