Package-Level Functions (total 25, in which 10 are exported)

	 func GenerateKey() (*PrivateKey, error)
		GenerateKey generates a new Ed25519 private key pair.

	 func NewPrivateKey(priv []byte) (*PrivateKey, error)
	 func NewPrivateKeyFromSeed(seed []byte) (*PrivateKey, error)
	 func NewPublicKey(pub []byte) (*PublicKey, error)
	 func Sign(priv *PrivateKey, message []byte) []byte
	 func SignCtx(priv *PrivateKey, message []byte, context string) ([]byte, error)
	 func SignPH(priv *PrivateKey, message []byte, context string) ([]byte, error)
	 func Verify(pub *PublicKey, message, sig []byte) error
	 func VerifyCtx(pub *PublicKey, message []byte, sig []byte, context string) error

	 func generateKey(priv *PrivateKey) (*PrivateKey, error)
	 func newPrivateKey(priv *PrivateKey, privBytes []byte) (*PrivateKey, error)
	 func newPrivateKeyFromSeed(priv *PrivateKey, seed []byte) (*PrivateKey, error)
	 func newPublicKey(pub *PublicKey, pubBytes []byte) (*PublicKey, error)
	 func pairwiseTest(k *PrivateKey) error

Package-Level Variables (only one, which is unexported)

	/* one unexported ... *//* one unexported: */
	  var fipsSelfTest func()
Package-Level Constants (total 8, none are exported)

	/* 8 unexporteds ... *//* 8 unexporteds: */
	const domPrefixCtx = "SigEd25519 no Ed25519 collisions\x00"
		domPrefixCtx is dom2(phflag=0) for Ed25519ctx. It must be followed by the
		uint8-length prefixed context.

	const domPrefixPh = "SigEd25519 no Ed25519 collisions\x01"
		domPrefixPh is dom2(phflag=1) for Ed25519ph. It must be followed by the
		uint8-length prefixed context.

	const domPrefixPure = ""
		domPrefixPure is empty for pure Ed25519.
