使用python/bcrypt将密码保存为mongodb中用户集合中的含盐哈希

问题描述

我想生成一个加盐的密码哈希，并将其存储在称为用户的MongoDB集合中，如下所示:

I want to generate a salted password hash and store it in MongoDB collection called users, like this:

users_doc = { 
    "username": "James",
    "password": "<salted_hash_password>"
}

我不确定如何使用Bcrypt生成哈希密码，然后在我登录flask应用程序时，能够检查哈希值是否与存储在MongoDB中的哈希密码匹配.

I'm not sure how to generate the hashed password using Bcrypt, then when I login in my flask app, be able to check if the hash matches with the hashed password stored in MongoDB.

推荐答案

我不知道您如何使用mongodb来带来数据，但是如果您想对传递的哈希进行哈希处理，就像这样:

I don't know how you use mongodb to bring the data, but if you want to hash the pass it's as easy as:

from flask import Flask
from flask.ext.bcrypt import Bcrypt

app = Flask(__name__)
bcrypt = Bcrypt(app)

# Your code here...

users_doc = {
    "username": "james",
    "password": bcrypt.generate_password_hash(password)
}

然后，如果要检查密码，可以使用 check_password_hash() 函数:

And then if you want to check the password, you can use the check_password_hash() function:

bcrypt.check_password_hash(users_doc["password"], request.form["password"]) # Just an example of how you could use it.
