你还在以明文形式存储密码吗？
优点：自我可见 缺点：不安全，不靠谱，不负责 以下讲述使用Md5对密码进行加密，验证，也有可能被暴力破解，大家可以按key…value的形式加密，增加破解难度！
)1 密码加密我使用的python3+,导入hashlib来操作Md5。
pip install hashlib
register.html
register
#register{
position: absolute;
top: 0px;
width: 88%;
padding: 18px 6% 60px 6%;
margin: 0 0 35px 0;
background: rgb(247, 247, 247);
border: 1px solid rgba(147, 184, 189,0.8);
box-shadow:
0pt 2px 5px rgba(105, 108, 109, 0.7),
0px 0px 8px 5px rgba(208, 223, 226, 0.4) inset;
border-radius: 5px;
}
#register{
z-index: 22;
}
.btn{
margin-left: 120px;
text-align: center;
width: 4%;
}
label{
font-family: 楷体;
}
{% csrf_token %}

import hashlib
from django.shortcuts import render
def register(request):
if request.method == 'GET':
return render(request, 'register.html')
if request.method == 'POST':
username = request.POST.get('usr')
password = request.POST.get('pwd')
Encry = hashlib.md5() # 实例化md5
Encry.update(password.encode()) # 字符串字节加密
md5_pwd = Encry.hexdigest() # 字符串加密
if username and password and repeat_password:
if password == repeat_password: # 输入密码是否一致
user_project = Users.objects.filter(username=username).first() #库中是否存在此账号
if user_project:
return render(request,'register.html',{'register_error':'账号已存在'})
else:
Users.objects.create(username=username, password=md5_pwd).save() # 保存账号密码
return redirect('/login') # 注册成功，返回登录页
else:
return render(request,'register.html',{'register_error':'两次密码输入不一致'})
注册成功，通过注册账号的案例成功加密，接下来就是验证登录！ 
login.html
登录

# 用户登陆
def login(request):
if request.method == "POST":
# 获取用户通过POST提交过来的数据
user = request.POST.get('usm')
pwd = request.POST.get('pwd')
Encry = hashlib.md5() # 实例化md5
Encry.update(pwd.encode()) # 字符串字节加密
password = Encry.hexdigest() # 字符串加密
if Users.objects.filter(username=user): # 是否有此用户
if Users.objects.filter(username=user)[0].password == password: #判断用户密码是否一致
users = Users.objects.filter(username=user, password=password)
return redirect('next_step/?user={}'.format(user))
else:
return render(request,'login.html',{'login_error':'用户名或密码错误'})
else:
return render(request,'login.html',{'login_error':'用户不存在'})
return render(request, 'login.html')
把前端输入的密码通过加密，判断与数据库保存的密码是否一致，一致就返回成功页面！
)3 修改密码修改密码要注意：因为会输入两个密码，判等的是原密码，修改的是新密码，所以两者都要进行加密！！！ change_pwd.html
register
#change_pwd{
position: absolute;
top: 0px;
width: 88%;
padding: 18px 6% 60px 6%;
margin: 0 0 35px 0;
background: rgb(247, 247, 247);
border: 1px solid rgba(147, 184, 189,0.8);
box-shadow:
0pt 2px 5px rgba(105, 108, 109, 0.7),
0px 0px 8px 5px rgba(208, 223, 226, 0.4) inset;
border-radius: 5px;
}
#change_pwd{
z-index: 22;
}
.btn{
margin-left: 120px;
text-align: center;
width: 4%;
}
label{
font-family: 楷体;
}
{% csrf_token %}

一定要严格要求自己，不要觉得方便，无所谓，从而以简代繁！
