| Architecture |
| ============ |
| |
| .. warning:: |
| |
| Because ``cryptography`` is so young, much of this document is |
| aspirational, rather than documentation. |
| |
| ``cryptography`` has three different layers: |
| |
| * ``cryptography``: This package contains higher level recipes, for example |
| "encrypt and then MAC". This is implemented on top of |
| ``cryptography.hazmat.primitives``. |
| * ``cryptography.hazmat.primitives``: This packages contains low level |
| algorithms, things like ``AES`` or ``SHA1``. This is implemented on top of |
| ``cryptography.hazmat.bindings``. |
| * ``cryptography.hazmat.bindings``: This package contains bindings to low level |
| cryptographic libraries. Our initial target will be OpenSSL. |
