存储和验证加密密码以便在Pyramid中登录

Question

我试图login在Pyramid中验证加密密码.因此,如果用户和密码匹配,则系统将授权用户.目前我发现在数据库中加密密码并且输入金字塔login形式的密码未加密时,编写一个比较密码的函数很困难.现在,我没有在登录视图中进行验证.

我是处理安全措施/代码的整个过程的新手,并希望这样做.我正在看这个Auth教程,但是User课堂上的加密略有不同,我正在使用Pyramid的Auth工具包.任何关于如何成功和巧妙地做到这一点的指导将受到高度赞赏.

软件:Python 2.7.9,Pyramid 1.5.7,SQLAlchemy 1.0.9

数据库类:

class User(Base):
    __tablename__ = 'users'

    id = Column(Integer, primary_key=True)
    username = Column(String(15), nullable=False, unique=True)
    email = Column(String(300))
    password = Column(String(300), nullable=False)

    def __init__(self, username, password, email):
        self.username = username
        self.password = hashlib.sha224(password).hexdigest()
        self.email = email

    def __repr__(self):
        return "<User(username ='%s', password='%s', email='%s')>" % (self.username, self.password, self.email)

@view_config(route_name='login', renderer='templates/login.jinja2')
@forbidden_view_config(renderer='templates/login.jinja2')
def login(request):
    login_url = request.route_url('login')
    referrer = request.url
    if referrer == login_url:
        referrer = '/' # never use the login form itself as came_from
    came_from = request.params.get('came_from', referrer)
    message = ''
    login = ''
    password = ''
    if 'form.submitted' in request.params:
        login = request.params['login']
        password = request.params['password']

        user = api.retrieve_user(login) # need some way to validate password
        if user is not None: # need to check user/password here, redirect if wrong
            headers = remember(request, login)
            return HTTPFound(location = came_from,
                             headers = headers)
            message = 'Failed login'

    return dict(
        message = message,
        url = request.application_url + '/login',
        came_from = came_from,
        login = login,
        password = password,
        )

请修改您的代码,添加优秀的passlib库,并使用bcrypt作为哈希算法使用安全密码存储.

在您的项目setup.py中添加以下内容作为要求:

• bcrypt
• passlib

然后为您的模型使用以下代码段:

from passlib.hash import bcrypt

class User(Base):
    __tablename__ = 'users'

    id = Column(Integer, primary_key=True)
    username = Column(String(15), nullable=False, unique=True)
    email = Column(String(300))
    password = Column(String(300), nullable=False)

    def __init__(self, username, password, email):
        self.username = username
        self.password = bcrypt.encrypt(password)
        self.email = email

    def validate_password(self, password):
        return bcrypt.verify(password, self.password)

    def __repr__(self):
        return "<User(username ='%s', password='%s', email='%s')>" % (self.username, self.password, self.email)
