使用Node.js和MongoDB存储密码

问题描述：

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

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

我想让一切都使用独特的盐

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

对于验证，我只是盐和加密输入并将其匹配到一个存储的哈希？

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

我应该需要解密此数据，如果是这样，我该怎么办？

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

甚至是安全存储在服务器上的盐化方法？

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

我听说过AES和Blowfish都是好的选择，我应该使用什么？

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

如何设计此示例的任何示例都将非常有用！

谢谢！

使用： https：// github。 com / ncb000gt / node.bcrypt.js /

bcrypt是关注此用例的几个算法之一。您应该永远无法解密密码，只验证用户输入的明文密码与存储/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非常简单易用。这里是我的Mongoose用户模式（在CoffeeScript）的代码段。确保使用异步函数作为bycrypt是慢的（有意）。

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，这应该说服你bcrypt是一个好的选择，并帮助你避免变得好，真正的效果。

Also, read this article, which should convince you that bcrypt is a good choice and help you avoid becoming "well and truly effed".
