Question

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

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

这是到目前为止：

pip install django-extensions

将'django_extensions'添加到INSTALLED_APPS

pip install python-keyczar

使用EncryptedCharField

创建了一个模型+添加的字段

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

已下载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 =“first key”--asymmetric = rsa

到目前为止一切顺利，但是当我运行我的服务器时，我收到以下错误：

keyczar.errors.KeyNotFoundError：带有hash_val标识符的密钥未找到。

    iban_enc = EncryptedCharField(max_length=155)

    super(EncryptedCharField, self).__init__(*args, **kwargs)
  File "/Users/nv/Projects/project/lib/python2.7/site-packages/django_extensions/db/fields/encrypted.py", line 32, in __init__
    max_length = len(self.prefix) + len(self.crypt.Encrypt('x' * max_length))
  File "/Users/nv/Projects/project/lib/python2.7/site-packages/keyczar/keyczar.py", line 338, in Encrypt
    encrypting_key = self.primary_key
  File "/Users/nv/Projects/project/lib/python2.7/site-packages/keyczar/keyczar.py", line 73, in <lambda>
    primary_key = property(lambda self: self.GetKey(self.primary_version),
  File "/Users/nv/Projects/project/lib/python2.7/site-packages/keyczar/keyczar.py", line 128, in GetKey
    raise errors.KeyNotFoundError(key_id)
keyczar.errors.KeyNotFoundError: Key with hash_val identifier None not found.

我无法弄清楚我做错了什么。

Answer 1

找到解决方案

创建后：

java -jar KeyczarTool-0.71g-090613.jar addkey --location =。/ enc-keys --status =“primary”--size = 2048

Answer 2

找出JAVA（puach）的解决方案

试试这个

bin/keyczart create --location=keys --purpose=crypt --name=models &&     bin/keyczart addkey --location=keys --status=primary

确保密钥是项目中的文件夹，可能是/ var / keys ??或者你喜欢的地方
