• func DecFromHex(x string, key *[32]byte) (string, error)
• func Decrypt(ciphertext []byte, key *[32]byte) (plaintext []byte, err error)

Functions

func DecFromHex

func DecFromHex(x string, key *[32]byte) (string, error)

DecFromHex decodes hex encoded x and decrypts that with key

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 EncAndHex

func EncAndHex(x string, key *[32]byte) (string, error)

EncAndHex encrypts x with key and converts x to hex

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.
