type Cipher struct {
	KeyBytes []byte
	// contains filtered or unexported fields
}

Cipher is wrapper of the AES GCM cipher and stores the raw key bytes

func New(keyBytes []byte) (Cipher, error)

New constructs a new AES GCM cipher using the raw key bytes provided, the raw bytes must be either 16, 24, or 32 bytes

func (cipher *Cipher) Decrypt(cipherBytes []byte, nonce []byte) ([]byte, error)

Decrypt takes cipher bytes and output plain bytes, it is assumed the nonce is prefixed to cipher bytes if its value is not being provided

func (cipher *Cipher) Encrypt(plainBytes []byte, prefixNonce bool) ([]byte, []byte, error)

Encrypt takes plain bytes and output cipher bytes, the nonce will be prefixed to cipher bytes if prefixNonce is true.
