Functions

func Decrypt

func Decrypt(encryptedData []byte, sharedKey *[SharedKeySize]byte, nonce *[NonceSize]byte) ([]byte, error)

Decrypt uses a crypto_box_open_afternm-equivalent function to decrypt the given data.

func Encrypt

func Encrypt(data []byte, sharedKey *[SharedKeySize]byte) ([]byte, *[NonceSize]byte, error)

Encrypt uses a crypto_box_afternm-equivalent function to encrypt the given data.

func GenerateKeyPair

func GenerateKeyPair() (*[PublicKeySize]byte, *[SecretKeySize]byte, error)

GenerateKeyPair generates a new curve25519 keypair.

func GenerateNonce

func GenerateNonce() (*[NonceSize]byte, error)

GenerateNonce generates a random nonce.

func GeneratePingID

func GeneratePingID() (uint64, error)

GeneratePingID generates a new random ping ID.

func PrecomputeKey

func PrecomputeKey(publicKey *[PublicKeySize]byte, secretKey *[SecretKeySize]byte) *[SharedKeySize]byte

PrecomputeKey calculates the shared key between the peer's publicKey and our own secret key.
