| # Interface for streaming authenticated encryption with associated data. |
| # Streaming encryption is typically used for encrypting large plaintexts |
| # such as large files. This interface supports a streaming interface for |
| # symmetric encryption with authentication. The underlying encryption modes |
| # are selected so that partial plaintext can be obtained fast by decrypting |
| # and authenticating just a part of the ciphertext. |

| # The cliffed CC primitive's only purpose is to be stored as a member |
| # variable and later be passed to a wrapper function (which sidesteps |
| # cliffing an OutputStream). Therefore Python doesn't need to know about |
| # its methods, just that it exists. |
