     5  // Package edwards25519 implements group logic for the twisted Edwards curve
     6  //
     7  //	-x^2 + y^2 = 1 + -(121665/121666)*x^2*y^2
     8  //
     9  // This is better known as the Edwards curve equivalent to Curve25519, and is
    10  // the curve used by the Ed25519 signature scheme.
    11  //
    12  // Most users don't need this package, and should instead use crypto/ed25519 for
    13  // signatures, golang.org/x/crypto/curve25519 for Diffie-Hellman, or
    14  // github.com/gtank/ristretto255 for prime order group logic.
    15  //
    16  // However, developers who do need to interact with low-level edwards25519
    17  // operations can use filippo.io/edwards25519, an extended version of this
    18  // package repackaged as an importable module.
    19  //
    20  // (Note that filippo.io/edwards25519 and github.com/gtank/ristretto255 are not
    21  // maintained by the Go team and are not covered by the Go 1 Compatibility Promise.)
