Functions

func Decrypt

func Decrypt(ciphertext []byte, key *[32]byte) (plaintext []byte, err error)

Decrypt decrypts data using 256-bit AES-GCM. This both hides the content of the data and provides a check that it hasn't been altered. Expects input form nonce|ciphertext|tag where '|' indicates concatenation.

func Encrypt

func Encrypt(plaintext []byte, key *[32]byte) (ciphertext []byte, err error)

Encrypt encrypts data using 256-bit AES-GCM. This both hides the content of the data and provides a check that it hasn't been altered. Output takes the form nonce|ciphertext|tag where '|' indicates concatenation.

func GenerateRandomBytes

func GenerateRandomBytes(n int) (string, error)

GenerateRandomBytes generates a random string of n bytes.

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.
