使用 Node.js 和 MongoDB 存储密码

2022-01-10 00:00:00 mongodb node.js cryptography aes javascript

我正在寻找一些如何使用 node.js 和 mongodb 安全存储密码和其他敏感数据的示例.

I'm looking for some examples of how to securely store passwords and other sensitive data using node.js and mongodb.

我希望所有内容都使用唯一的盐,我将在 mongo 文档中与哈希一起存储.

I want everything to use a unique salt that I will store along side the hash in the mongo document.

对于身份验证,我是否必须对输入进行加盐和加密并将其与存储的哈希匹配?

For authentication do I have to just salt and encrypt the input and match it to a stored hash?

我是否需要解密这些数据?如果需要,我应该怎么做?

Should I ever need to decrypt this data and if so how should I do it?

私钥,甚至加盐方法如何安全地存储在服务器上?

How are the private keys, or even salting methods securely stored on the server?

我听说 AES 和 Blowfish 都是不错的选择,我应该使用什么?

I've heard the AES and Blowfish are both good options, what should I use?

任何有关如何设计的示例都会非常有帮助!

谢谢!

bcrypt 是少数几个专注于这个用例的算法之一.您永远无法解密您的密码,只能验证用户输入的明文密码是否与存储/加密的哈希值匹配.

bcrypt is one of just a few algorithms focused on this use case. You should never be able to decrypt your passwords, only verify that a user-entered cleartext password matches the stored/encrypted hash.

bcrypt 使用起来非常简单.这是我的 Mongoose 用户模式的一个片段(在 CoffeeScript 中).请务必使用异步函数,因为 bycrypt 很慢(故意).

bcrypt is very straightforward to use. Here is a snippet from my Mongoose User schema (in CoffeeScript). Be sure to use the async functions as bycrypt is slow (on purpose).

class User extends SharedUser
  defaults: _.extend {domainId: null}, SharedUser::defaults

  #Irrelevant bits trimmed...

  password: (cleartext, confirm, callback) ->
    errorInfo = new errors.InvalidData()
    if cleartext != confirm
      errorInfo.message = 'please type the same password twice'
      errorInfo.errors.confirmPassword = 'must match the password'
      return callback errorInfo
    message = min4 cleartext
    if message
      errorInfo.message = message
      errorInfo.errors.password = message
      return callback errorInfo
    self = this
    bcrypt.gen_salt 10, (error, salt)->
      if error
        errorInfo = new errors.InternalError error.message
        return callback errorInfo
      bcrypt.encrypt cleartext, salt, (error, hash)->
        if error
          errorInfo = new errors.InternalError error.message
          return callback errorInfo
        self.attributes.bcryptedPassword = hash
        return callback()

  verifyPassword: (cleartext, callback) ->
    bcrypt.compare cleartext, @attributes.bcryptedPassword, (error, result)->
      if error
        return callback(new errors.InternalError(error.message))
      callback null, result

另外,请阅读 这篇文章,它应该让你相信 bcrypt 是一个很好的选择并帮助您避免变得真正有效".
