A common mistake is to focus on the encryption algorithm while treating key storage as a secondary detail. If an attacker can obtain both the ciphertext and the key that decrypts it, the encryption no longer provides the intended protection.</p> <p>Envelope encryption addresses this operational problem by using different keys for different jobs. A <strong>data encryption key</strong> encrypts the data, while a separate <strong>key-encryption key</strong> protects the data key. This separation makes it possible to encrypt many pieces of data without storing their plaintext data keys beside them.</p>
