Exported Values

const KeySize = 32 KeySize is the size of the key used by this AEAD, in bytes.
func New(key []byte) (cipher.AEAD, error) New returns a ChaCha20-Poly1305 AEAD that uses the given 256-bit key.
func NewX(key []byte) (cipher.AEAD, error) NewX returns a XChaCha20-Poly1305 AEAD that uses the given 256-bit key. XChaCha20-Poly1305 is a ChaCha20-Poly1305 variant that takes a longer nonce, suitable to be generated randomly without risk of collisions. It should be preferred when nonce uniqueness cannot be trivially ensured, or whenever nonces are randomly generated.
const NonceSize = 12 NonceSize is the size of the nonce used with the standard variant of this AEAD, in bytes. Note that this is too short to be safely generated at random if the same key is reused more than 2³² times.
const NonceSizeX = 24 NonceSizeX is the size of the nonce used with the XChaCha20-Poly1305 variant of this AEAD, in bytes.
