func NewKeyFromSeed

func NewKeyFromSeed(seed [SeedSize]byte) (PublicKey, PrivateKey)

NewKeyFromSeed calculates a private key and a public key from a seed. RFC 8032's private keys correspond to seeds in this package.

func Sign

func Sign(privateKey PrivateKey, message []byte) []byte

Sign signs the message with privateKey and returns the signature.

type PrivateKey [PrivateKeySize]byte

PrivateKey defines the Ed25519 private key.

type PublicKey [PublicKeySize]byte

PublicKey defines the Ed25519 public key.
