	// contains filtered or unexported fields
}

Encryptor wraps AES-256-GCM authenticated encryption. The key is derived from an arbitrary-length secret via SHA-256.

func New(secret string) *Encryptor

New derives a 32-byte AES key from secret and returns an Encryptor.

func (e *Encryptor) Decrypt(ciphertext string) (string, error)

Decrypt decodes and decrypts the base64 blob produced by Encrypt.

func (e *Encryptor) Encrypt(plaintext string) (string, error)

Encrypt encrypts plaintext and returns a URL-safe base64 string. Layout: [12-byte nonce][ciphertext+16-byte GCM tag].
