NonceSize defines the nonce length when creating new keys

Functions

func New

func New() ([]byte, error)

New returns a new data key

func RandomBytes

func RandomBytes(value *[]byte) error

RandomBytes fills a slice with random bytes

Types

type Service

type Service struct {
	// contains filtered or unexported fields
}

Service operates on bytes with a data key

func NewService

func NewService(key []byte) *Service

NewService returns an AES service for a given key

func (*Service) Decrypt

func (svc *Service) Decrypt(encryptedBytes []byte) (plainText string, err error)

Decrypt returns a plaintext string

func (*Service) DecryptAsBytes

func (svc *Service) DecryptAsBytes(encryptedBytes []byte) (plainBytes []byte, err error)

DecryptAsBytes returns decrypted bytes

func (*Service) Encrypt

func (svc *Service) Encrypt(plainText []byte) (cipherText []byte, err error)

Encrypt plaintext bytes into ciphertext
