Functions

func UnsafeBrokenRepresentativeToPublicKey

func UnsafeBrokenRepresentativeToPublicKey(publicKey, representative *[32]byte)

UnsafeBrokenRepresentativeToPublicKey converts a uniform representative value for a curve25519 public key, as produced by UnsafeBrokenScalarBaseMult, to a curve25519 public key.

func UnsafeBrokenScalarBaseMult

func UnsafeBrokenScalarBaseMult(publicKey, representative, privateKey *[32]byte) bool

UnsafeBrokenScalarBaseMult computes a curve25519 public key from a private key and also a uniform representative for that public key. Note that this function will fail and return false for about half of private keys. See http://elligator.cr.yp.to/elligator-20130828.pdf.
