• Kumar McMillan did a lot of this work.

Usage

Like any other field:

from aesfield.field import AESField

class SomeModel(...):
    key = AESField()

Configuration

AESField takes the following parameters beyond a normal CharField:

• aes_prefix: the prefix to use on fields, defaults to aes:

• aes_key: the key to use in the lookup method to find a suitable key for this field, defaults to default

Settings:

• AES_METHOD: the module to look in for a key lookup method, if you want something different from the default, aesfield.default

• AES_KEYS: used by the aesfield.default method. It’s a dictionary of keys to filenames. Those files must be able to be read by the Django process. It must have a default key, unless you specify a specifc one in aes_key

Commands

If you add aesfield to INSTALLED_APPS you’ll get one more command, generate_aes_keys. This will generate a new file for each file mentioned in the AES_KEYS dictionary. But only if that file does not already exist.
