Functions

func Decrypt

func Decrypt(key, data []byte) (plaintext []byte, err error)

Decrypt decrypts ciphertext data using using chacha20poly1305. This encryption algorithm is initialized by passing in the encryption key, which must be 256 bits.

func Encrypt

func Encrypt(key, data []byte, rng csprng.Source) (ciphertext []byte, error error)

Encrypt encrypts plaintext data using using chacha20poly1305. This encryption algorithm is initialized by passing in the encryption key, which must be 256 bits.
