Functions

func ED25519GenerateKey

func ED25519GenerateKey(str string) ([]byte, []byte, error)

ED25519GenerateKey return a public and private ED25519 key pair from a string.

func ED25519Signature

func ED25519Signature(key, data []byte) ([]byte, error)

ED25519Signature returns the ED25519 signature of data using the key.

func ValidateED25519Signature

func ValidateED25519Signature(key, data, signature []byte) bool

ValidateED25519Signature return true when the ED25519 signature is a valid signature of the data based on the key, otherwise false.

Types

type Cryptographer

type Cryptographer interface {
	Encrypter
	Decrypter
}

A Cryptographer is a De- and Encrypter.

func NewSecureClientSessionFromSharedKey

func NewSecureClientSessionFromSharedKey(sharedKey [32]byte) (Cryptographer, error)

NewSecureClientSessionFromSharedKey returns a session from a shared secret key to simulate a HomeKit client. This is currently only used for testing.

func NewSecureSessionFromSharedKey

func NewSecureSessionFromSharedKey(sharedKey [32]byte) (Cryptographer, error)

NewSecureSessionFromSharedKey returns a session from a shared private key.

type Decrypter

type Decrypter interface {
	Decrypt(r io.Reader) (io.Reader, error)
}

Decrypter decrypts bytes.

type Encrypter

type Encrypter interface {
	Encrypt(r io.Reader) (io.Reader, error)
}

Encrypter encrypts bytes.
