django-extensions - 如何使用加密字符字段

Question

是否有任何文档或示例/教程如何让 EncryptedCharField 在 Django 模型中工作？

我花了很多时间在我的 django 项目中安装 django-extension + keyczar 等。没有文档如何安装它。

这是到目前为止的结果:

pip 安装 django 扩展

将“django_extensions”添加到 INSTALLED_APPS

pip 安装 python-keyczar

创建模型 + 使用 EncryptedCharField 添加字段

添加了 ENCRYPTED_FIELD_KEYS_DIR = '../../../enc-keys'

下载KeyczarTool-0.71g-090613.jar

运行以下命令:java -jar KeyczarTool-0.71g-090613.jar create --location=./enc-keys --purpose=crypt --name="第一个 key "--asymmetric=rsa

到目前为止一切顺利，但是当我运行我的服务器时出现以下错误:

keyczar.errors.KeyNotFoundError:未找到带有 hash_val 标识符的 key 。

    raise errors.KeyNotFoundError(key_id)
keyczar.errors.KeyNotFoundError: Key with hash_val identifier None not found.

我不知道我做错了什么。
