Functions

func Sha256Hash

func Sha256Hash(msg []byte) []byte

Sha256Hash returns the SHA-256 hash of a message as a byte slice.

func SignSymmetric

func SignSymmetric(msg []byte, secretKey *[32]byte) ([]byte, error)

SignSymmetric signs a message using a symmetric key. It is a convenience wrapper around the nacl/auth package.

func VerifyAndReadAssymetric

func VerifyAndReadAssymetric(signedMsg []byte, publicKey *[32]byte) ([]byte, error)

VerifyAndReadAssymetric verifies a signed message using a public key and returns the original message. It is a convenience wrapper around the nacl/sign package.

func VerifyAndReadAssymetricBase64

func VerifyAndReadAssymetricBase64(signedMsg Base64, publicKey Base64) ([]byte, error)

VerifyAndReadAssymetricBase64 verifies a signed message using a base64 encoded public key and returns the original message. It is a convenience wrapper around the nacl/sign package.

func VerifyAndReadSymmetric

func VerifyAndReadSymmetric(signedMsg []byte, secretKey *[32]byte) ([]byte, error)

VerifyAndReadSymmetric verifies a signed message using a symmetric key and returns the original message. It is a convenience wrapper around the nacl/auth package.
