  4. // Package edwards25519 implements group logic for the twisted Edwards curve
  5. //
  6. // -x^2 + y^2 = 1 + -(121665/121666)*x^2*y^2
  7. //
  8. // This is better known as the Edwards curve equivalent to Curve25519, and is
  9. // the curve used by the Ed25519 signature scheme.
  10. //
  11. // Most users don't need this package, and should instead use crypto/ed25519 for
  12. // signatures, golang.org/x/crypto/curve25519 for Diffie-Hellman, or
  13. // github.com/gtank/ristretto255 for prime order group logic.
  14. //
  15. // However, developers who do need to interact with low-level edwards25519
  16. // operations can use this package, which is an extended version of
  17. // crypto/internal/edwards25519 from the standard library repackaged as
  18. // an importable module.
