Functions

func Decrypt

func Decrypt(in io.Reader, out io.Writer, size int64, key *[32]byte) error

Decrypt decrypts data using 256-bit AES-CTR and provides message authentication verifying the HMAC-512_256 signature.

func Encrypt

func Encrypt(in io.Reader, out io.Writer, key *[32]byte) error

Encrypt encrypts data using 256-bit AES-CTR and provides message authentication by signing the data with HMAC-512_256.

func NewEncryptionKey

func NewEncryptionKey() *[32]byte

NewEncryptionKey generates a random 256-bit key for Encrypt() and Decrypt(). It panics if the source of randomness fails.

func NewRandomIV

func NewRandomIV() []byte

NewRandomIV generates a random 128-bit IV for use with AES encryption. It panics if the source of randomness fails.
