| // 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 filippo.io/edwards25519, an extended version of this |
| // package repackaged as an importable module. |
| // |
| // (Note that filippo.io/edwards25519 and github.com/gtank/ristretto255 are not |
| // maintained by the Go team and are not covered by the Go 1 Compatibility Promise.) |
