Python 如何使用 Django 使用 pbkdf2_sha256 散列存储在 mysql 中的密码

我有以纯文本形式存储的用户密码列表.我想我需要一个脚本来运行存储的密码并对它们进行哈希处理.我对Django还不熟悉，不知道从哪里开始，也不知道如何开始.

我创建了登录帐户，而创建帐户仅适用于新用户:

@admin_login_required
def add_emp(request):
    if request.method == 'POST':
        user_name = request.POST['user_name']
        user_email = request.POST['user_email']
        user_otj = request.POST['user_otj']
        user_password = pwo.generate()
        user_password1 = make_password(user_password)
        empObj = User.objects.create(user_name=user_name, user_email=user_email, user_password=user_password1, user_otj=user_otj)
        if empObj:
            subject = 'Advanced Analytics Portal - Login Info'
            message = f'Name : {user_name}, \n Email : {user_email}, \n Password : {user_password} \n FROM - AA Portal'
            email_from = settings.EMAIL_HOST_USER
            send_mail(subject, message, email_from, [user_email])
            messages.success(request, "Employee was added successfully!")
            return HttpResponseRedirect('/create-emp')
        else:
            messages.error(request, "Some error was occurred!")
            return HttpResponseRedirect('/create-emp')
    return render(request, 'AddEmp.html')

def user_login(request):
    if request.method == "POST":
        user_email = request.POST['user_email']
        user_password = request.POST['user_password']
        user_details = User.objects.filter(user_email=user_email).first()

        if user_details and check_password(user_password, user_details.user_password):
            request.session['logged_in'] = True
            request.session['user_email'] = user_details.user_email
            request.session['u_id'] = user_details.user_email
            request.session['user_name'] = user_details.user_name
            request.session['u_type'] = "emp"
            return HttpResponseRedirect('/user_index')
        else:
            return render(request, 'EmpLogin.html', {'msg': "0"})
    else:
        return render(request, 'EmpLogin.html')

如何让以前的用户在不为其创建新帐户的情况下登录.
