Question

我设法使用cryptojs和bcrypt哈希/加密我所有的密码，但是失败了比较散列（数据库中的散列密码与散列的输入密码）总是返回false 所以我做了更多的工作以找出哈希的内容，这些就是结果。

const crypto = require('crypto')
function setUserPassword(inputPassword){
    const salt = crypto.randomBytes(16).toString('hex')
  let hashedPassword = crypto.pbkdf2Sync(inputPassword, salt, 1000, 16,'sha512').toString('hex')
   return{ //we shall store them in the database later
     salt: salt,
     hashedPassword: hashedPassword
   }
}
database ====>ac0f74b30c94fedbbd591889c4705607  //works perefectly using the above function

challenge comes when validating the user password.. using this function..
   function validateUserPassword(enteredPassword, dbSalt, dbPassword){

// then checks if this generated hash is equal to user's hash in the database or not 
   let hashInput = crypto.pbkdf2Sync(enteredPassword, dbSalt, 1000,16, 'sha512') //the same as above

   //u must compare the hashed password in the db with hashedInput password
   return hashInput === dbPassword //IF it returns true then they match
}
so i checked the  hashInput and discovered that it was a buffer instead of the string... 
hey hashed input password  <Buffer ac 0f 74 b3 0c 94 fe db bd 59 18 89 c4 70 56 07>

//may nodejs version... v6.11.4 and alo tried using v10.15.0 but all in  the vain.

在setUserPassword()中，您是从哈希函数返回的缓冲区中创建一个十六进制编码的字符串，但是您忘记了在validateUserPassword()中这样做。这将解决它：

let hashInput = crypto.pbkdf2Sync(enteredPassword, dbSalt, 1000,16, 'sha512').toString('hex')

为什么所有的brcypt或crypto哈希比较总是返回false，即使输入正确的密码也是如此
