Functions
int	n_ed25519_keypair (unsigned char *priv, unsigned char *pub)
	generate an Ed25519 keypair as N_ECC_KEY_LEN-byte raw private and public keys.
int	n_ed25519_sign (const unsigned char *priv, const unsigned char *msg, size_t len, unsigned char *sig)
	Ed25519 sign len bytes of msg with the N_ECC_KEY_LEN-byte raw private key into sig (N_ECC_SIG_LEN bytes).
int	n_ed25519_verify (const unsigned char *pub, const unsigned char *msg, size_t len, const unsigned char *sig)
	Ed25519 verify the N_ECC_SIG_LEN-byte sig over len bytes of msg under the N_ECC_KEY_LEN-byte raw public key.
int	n_x25519_derive (const unsigned char *priv, const unsigned char *peer_pub, unsigned char *shared)
	X25519 ECDH: derive the N_ECC_KEY_LEN-byte shared secret from our raw private key and the peer's raw public key.
int	n_x25519_keypair (unsigned char *priv, unsigned char *pub)
	generate an X25519 keypair as N_ECC_KEY_LEN-byte raw private and public keys.
