| Architecture |
| ============ |
| |
| ``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.backends``. |
| * ``cryptography.hazmat.backends``: This package contains bindings to low level |
| cryptographic libraries. Our initial target is OpenSSL. |
