var ErrNoKey = errors.New("crypto: no secret key configured")

Types ¶

type Sealer ¶

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

Sealer encrypts and decrypts secrets. A nil Sealer is valid and returns ErrNoKey from Seal/Open, so callers can construct one unconditionally and fail only when a secret is actually used.

func NewSealer ¶

func NewSealer(passphrase string) (*Sealer, error)

NewSealer derives an AES-256 key from the passphrase. An empty passphrase yields a nil Sealer that rejects secret operations.

func (*Sealer) Open ¶

func (s *Sealer) Open(sealed []byte) ([]byte, error)

Open reverses Seal.

func (*Sealer) Seal ¶

func (s *Sealer) Seal(plaintext []byte) ([]byte, error)

Seal returns nonce||ciphertext for the plaintext.
