Shipped Fields

Mixins

• SafeFieldMixinBase
• SafeStringFieldMixin
• SafeIntegerFieldMixin

Fields

• SafeCharField
• SafeTextField
• SafeEmailField
• SafeURLField
• SafeGenericIPAddressField
• SafeIntegerField

Note

1. Default cipher is aes-128-ecb. It keeps the same with mysql's aes_encrypt and aes_decrypt when server variable block_encryption_mode=aes-128-ecb.
2. Default password is settings.SECRET_KEY, but we STRONGLY suggest you use different password for every different field.

Usage

pro/settings.py

INSTALLED_APPS = [
    ...
    'django_safe_fields',
    ...
]

1. Insert django_safe_fields into INSTALLED_APPS.

app/models.py

from django.db import models
from django.conf import settings
from django_safe_fields.fields import SafeCharField
from django_safe_fields.fields import SafeGenericIPAddressField
from django_safe_fields.fields import SafeIntegerField
from fastutils.cipherutils import S12Cipher
from fastutils.cipherutils import HexlifyEncoder

class Account(models.Model):
    username = SafeCharField(max_length=64)
    name = SafeCharField(max_length=64, cipher_class=S12Cipher)
    email = SafeCharField(max_length=128, null=True, blank=True, cipher=S12Cipher(password=settings.SECRET_KEY, encoder=HexlifyEncoder(), force_text=True))
    last_login_ip = SafeGenericIPAddressField(max_length=256, null=True, blank=True, password="THIS FIELD PASSWORD")
    level = SafeIntegerField(null=True, blank=True)

    def __str__(self):
        return self.username

1. All fields will be stored with encryption.
2. AesCipher is a strong cipher.
3. With aes encryption, you can NOT search partly, only the exact search rule will be accepted.
4. With aes encryption, you can NOT sort.
5. S12Cipher is a week cipher that let you search the field partly and also let you sort with the field.
6. IvCihper is a week cipher for integer field that let you sort with the field.
