CouchDB can optionally encrypt databases and views. We use AES in Counter Mode, which ensures we can encrypt and decrypt any section of the file without padding or alignment. The ciphertext is the same length as the plaintext. This mode provides confidentiality but not authentication. Key management is configurable, a system administrator can write a module implementing the aegis_key_manager behaviour with any implementation. CouchDB ships with an implementation that stores keys in the config file as an example, but this is not suitable for production.
