如何在 Django 中实现自定义密码哈希？

Question

所以我的经理要求我为我们的 django 网站实现 Base64 密码加密。我在 django.contrib.auth.hashers 中找不到任何 base64 哈希算法。所以，我认为我必须编写自己的 Hasher 模块。问题是，我不知道怎么办。我尝试阅读 django 文档，但我仍然不清楚。我只需要使用 Base64 加密将用户密码存储在数据库中。另外，我需要自定义用户身份验证才能相应地工作。

这是我的用户模型：

from django.contrib.auth.models import AbstractUser
from .managers import UserManager

class User( AbstractUser ) : 

    email = models.EmailField( verbose_name = 'Email Address', unique = True, null = False )
    username = None

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = []
    objects = UserManager()

    def __str__( self ) : return self.get_username()

这是我的用户管理器：

from django.contrib.auth.models import BaseUserManager

class UserManager( BaseUserManager ) : 

    def create_user( self, email = None, password = None, first_name = None, last_name = None ) :
        
        try : 

            user = self.model( email = self.normalize_email( email ) )
            user.set_password( password )
            user.is_active = True

            user.first_name = first_name
            user.last_name = last_name
                
            user.save( using = self._db )
            return user

        except Exception as e : raise Exception( e )
    


    def create_staffuser( self, email, password ) :

        try : 

            staffuser = self.create_user( email, password )
            staffuser.is_staff = True
            staffuser.save( using = self._db )

            return staffuser

        except Exception as e : raise Exception( e )



    def create_superuser( self, email = None, password = None ) :

        try : 

            superuser = self.create_staffuser( email, password )
            superuser.is_superuser = True
            superuser.save( using = self._db )

            return superuser

        except Exception as e : raise Exception( e )

这是我的 backends.py

from django.contrib.auth.backends import ModelBackend
from .models import User



class AuthBackend( ModelBackend ) : 

    def authenticate( email = None, password = None ) : 

        try : 

            user = User.objects.get( email = email )
            if user.check_password( password ) : return user
            else : raise Exception( 'Password Does Not Match...' )

        except Exception as e : raise Exception( str( e ) )
