节点bcrypt的比较总是返回false [英] Node bcrypt's compare always returns false

问题描述

我很想尝试使用节点成功获取密码以与bcrypt进行比较.也许我错过了一些事情，但是在创建帐户时，我在signup方法中执行了以下操作(缩写了一些代码):

I am stumped trying to get my passwords to successfully compare with bcrypt using node. Maybe I missed something, but on account creation, I do the following within the signup method (with some code abbreviated):

bcrypt.genSalt(10, function(err, salt) {
               if(err) {

               }
               bcrypt.hash(user.Password, salt, function(err, hash) {
                           console.log('hashing and saving');
                           db.query(db insert code, function (error, rows, fields) {
                                    if(error) {
                                    console.log(error);
                                    res.setHeader('500', { 'Content-Type': 'x-application/json'});
                                    res.send({UserId: 0, ErrorMessage: 'Something terrible happened.'});
                                    } else {
                                    console.log('User created : ' + rows.insertId);
                                    res.setHeader('200', { 'Content-Type': 'x-application/json'});
                                    res.send({UserId: rows.insertId});
                                    }
                                    });
                           });
               });

return next();

一切正常.我的数据库具有加密的密码.但是，当用户登录时，我无法从bcrypt.compare获得成功的结果:

This all works fine. My db has the encrypted password. But when a user signs in, I cannot get a successful result from bcrypt.compare:

db.query(get account code, function(error, rows, fields) {
         if(rows.length == 1) {
           bcrypt.compare(request.params.password, rows[0].Password, function(err,res) {
              if(err) { console.log(err.toString()); }
              if(res == true)
              {
                        response.setHeader('200', { 'Content-Type': 'x-application/json' });
                        response.send({result: true});
              } else {
                        response.setHeader('401', { 'Content-Type': 'x-application/json' });
                        console.log('invalid password');
                        response.send({result:false});
                     }
              });
         }
        });

return next();

而且我总是以无效的密码结尾.与从数据库中提取的密码进行比较之前，我需要使用明文密码并重新加密吗?

And I always end up with invalid password. Do I need to take the cleartext password and re-encrypt it before comparing to what I pull out of the database?

推荐答案

您可以跳过bcrypt.genSalt并使用bcrypt.hash(password, 10, function(err, hash) {..});

您的比较功能对我来说似乎很好.

your compare function seems good to me.

这对我来说很好:

var bcrypt = require('bcrypt');

bcrypt.hash('mypassword', 10, function(err, hash) {
    if (err) { throw (err); }

    bcrypt.compare('mypassword', hash, function(err, result) {
        if (err) { throw (err); }
        console.log(result);
    });
});
