// Package edwards25519 implements group logic for the twisted Edwards curve
|
||
|
|
//
|
||
|
|
// -x^2 + y^2 = 1 + -(121665/121666)*x^2*y^2
|
||
|
|
//
|
||
|
|
// This is better known as the Edwards curve equivalent to Curve25519, and is
|
||
|
|
// the curve used by the Ed25519 signature scheme.
|
||
|
|
//
|
||
|
|
// Most users don't need this package, and should instead use crypto/ed25519 for
|
||
|
|
// signatures, golang.org/x/crypto/curve25519 for Diffie-Hellman, or
|
||
|
|
// github.com/gtank/ristretto255 for prime order group logic.
|
||
|
|
//
|
||
|
|
// However, developers who do need to interact with low-level edwards25519
|
||
|
|
// operations can use this package, which is an extended version of
|
||
|
|
// crypto/ed25519/internal/edwards25519 from the standard library repackaged as
|
||
|
|
// an importable module.
