Functions

func GenerateKeyPair

func GenerateKeyPair() (PrivateKey, PublicKey, error)

GenerateKeyPair generates ed25519 private key and a public key derived from it.

func PrependPubkey

func PrependPubkey(message []byte, pubkey PublicKey) []byte

PrependPubkey adds a public key at the beginning on a byte array.

Types

type Key

type Key interface {
	Bytes() []byte

	Array() [32]byte
	String() string
	// contains filtered or unexported methods
}

Key represents a 32 bit cryptographic key, public or private.

type PrivateKey

type PrivateKey interface {
	Key
}

PrivateKey is a private key of 32 byte.

func NewPrivateKeyFromBase58

func NewPrivateKeyFromBase58(s string) (PrivateKey, error)

NewPrivateKeyFromBase58 creates a private key from a base58 string.

type PublicKey

type PublicKey interface {
	Key
}

PublicKey is a public key of 32 byte.

func ExtractPubkey

func ExtractPubkey(message []byte) ([]byte, PublicKey, error)

ExtractPubkey extracts a public key from the beginning of a byte array.

func NewPubkeyFromBytes

func NewPubkeyFromBytes(bytes []byte) (PublicKey, error)

NewPubkeyFromBytes creates a public key from a byte array.

func NewPublicKeyFromBase58

func NewPublicKeyFromBase58(s string) (PublicKey, error)

NewPublicKeyFromBase58 creates a public key from a base58 string.

func NewRandomPubkey

func NewRandomPubkey() PublicKey

NewRandomPubkey reads random bytes and creates a public key from them. used for testing

func PublicKeyFromArray

func PublicKeyFromArray(ke [32]byte) PublicKey

PublicKeyFromArray creates a public key using a fixed sized byte array.

type SharedSecret

type SharedSecret interface {
	Key
	Seal(message []byte) (out []byte)
	Open(encryptedMessage []byte) (out []byte, err error)
}

SharedSecret is created using two participants key to enable Sealing and Opening of messages (NaCL).

func GenerateSharedSecret

func GenerateSharedSecret(privkey PrivateKey, peerPubkey PublicKey) SharedSecret

GenerateSharedSecret creates a key derived from a private and a public key.
