Functions

func Decrypt

func Decrypt(priv *PrivateKey, vsG, m, curveOID, fingerprint []byte) (msg []byte, err error)

func Encrypt

func Encrypt(random io.Reader, pub *PublicKey, msg, curveOID, fingerprint []byte) (vsG, c []byte, err error)

func X25519Decrypt

func X25519Decrypt(priv *PrivateKey, vsG, m, curveOID, fingerprint []byte) (msg []byte, err error)

Types

type KDF

type KDF struct {
	Hash   algorithm.Hash
	Cipher algorithm.Cipher
}

type PrivateKey

type PrivateKey struct {
	PublicKey
	D []byte
}

func GenerateKey

func GenerateKey(c elliptic.Curve, kdf KDF, rand io.Reader) (priv *PrivateKey, err error)

func X25519GenerateKey

func X25519GenerateKey(rand io.Reader, kdf KDF) (priv *PrivateKey, err error)

X25519GenerateKey samples the key pair according to the correct distribution. It also sets the given key-derivation function and returns the *PrivateKey object along with an error.

type PublicKey

type PublicKey struct {
	ecc.CurveType
	elliptic.Curve
	X, Y *big.Int
	KDF
}
