| This bypasses the KMS-based :class:`CryptoFactory` API and directly | ||
| constructs decryption properties from a plaintext key. This is useful | ||
| when the caller manages key wrapping externally (e.g. via an | ||
| application-level envelope encryption scheme). | ||
|
|
||
| For most use cases, prefer the higher-level :class:`CryptoFactory` | ||
| with :class:`DecryptionConfiguration`, which handles envelope | ||
| encryption and key rotation automatically. |
