推荐答案

散列密码的全部意义在于，您不必以明文形式保存密码.如果有人可以获得散列密码，他就无法将它们转换回密码.另外，不要忘记 salt 您的哈希值，否则您的哈希密码很容易受到彩虹表.

The whole point of hashing a password is so that you do not have to save passwords in clear text. If someone can get the hashed passwords, he can't convert them back to passwords. Also, don't forget to salt your hashing otherwise your hashed passwords are vulnerable to rainbow tables.
