用盐散列在SHA512中? - Python [英] Hashing in SHA512 using a salt? - Python

问题描述

我一直在浏览hashlib文档，但没有发现有关在哈希数据时使用盐的任何讨论.

I have been looking through ths hashlib documentation but haven't found anything talking about using salt when hashing data.

帮助会很棒.

推荐答案

Samir的答案是正确的，但有些含糊.基本上，salt只是数据的随机衍生位，您可以在数据前添加前缀或后缀，以显着增加对哈希值进行字典攻击的复杂性.因此，给定盐s和数据d，您只需执行以下操作即可生成数据的盐化哈希值:

Samir's answer is correct but somewhat cryptic. Basically, the salt is just a randomly derived bit of data that you prefix or postfix your data with to dramatically increase the complexity of a dictionary attack on your hashed value. So given a salt s and data d you'd just do the following to generate a salted hash of the data:

import hashlib
hashlib.sha512( s + d ).hexdigest()
