Question

我正在尝试使用以下其他用户发布的以下问题的答案：

>>> # import the hash algorithm
>>> from passlib.hash import sha256_crypt

>>> # generate new salt, and hash a password
>>> hash = sha256_crypt.encrypt("toomanysecrets")
>>> hash

但是当我输入from passlib.hash import sha256_crypt时，我收到以下错误：

Traceback (most recent call last):   File "<stdin>", line 1, in
<module> ImportError: No module named passlib.hash
>>>

我已经完成了pip install passlib。有什么想法吗？

运行结果：pip install passlib：

Answer 1

您收到了“拒绝权限”错误。尝试

sudo pip install passlib

或

pip install --user passlib

Answer 2

安装passlib被拒绝，因此需要sudo运行：

sudo pip install passlib

归功于@Drewness，@ wnnmaw和@cmd

Answer 3

看起来你现在可以使用非常光滑的东西：

sqlalchemy_utils.types.password.PasswordType

然后SQLAlchemy将为您进行编码/解码。例如：

class User(Base):
    password = Column(PasswordType())

然后设置和获取是非常标准的python代码，并且所有实际操作都在幕后发生：

user = User()

# set password
user.password = 'foo'   # '$5$rounds=80000$H.............'

# check password
user.password == 'foo'  # true

使用Python passlib创建密码
