Types

type AESEncrypter

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

AESEncrypter wraps AES-GCM operations.

func NewAESEncrypter

func NewAESEncrypter(hexKey string) (*AESEncrypter, error)

NewAESEncrypter constructs an AESEncrypter from a hex-encoded key.

func (*AESEncrypter) Decrypt

func (a *AESEncrypter) Decrypt(
	ciphertext []byte, nonce []byte) ([]byte, error)

Decrypt decrypts ciphertext with the provided nonce.

func (*AESEncrypter) DecryptFromJSON

func (a *AESEncrypter) DecryptFromJSON(enc json.RawMessage) ([]byte, error)

DecryptFromJSON expects base64 fields and returns decrypted bytes.

func (*AESEncrypter) Encrypt

func (a *AESEncrypter) Encrypt(plaintext []byte, nonce []byte) ([]byte, error)

Encrypt encrypts plaintext with the provided nonce.

func (*AESEncrypter) EncryptToJSON

func (a *AESEncrypter) EncryptToJSON(
	payload json.RawMessage) (json.RawMessage, error)

EncryptToJSON returns a JSON object with base64 nonce and cipher for payload.
