javascript - Node.JS 对密码进行哈希处理时出现 Binding.PBKDF2 错误

Question

我尝试使用 crypto.PBKDF2 对用户模型中的密码进行哈希处理，但我的 validatePassword 方法失​​败并出现以下异常

return binding.PBKDF2(password, salt, iterations, keylen, digest, callback);

这是完整的错误

crypto.js:562
return binding.PBKDF2(password, salt, iterations, keylen, digest, callback);
               ^
TypeError: Not a buffer
    at TypeError (native)

    at Function.Module._load (module.js:301:12)

这些是相关方法

UserSchema.methods.setPassword = function(password){
    var self = this;

    crypto.randomBytes(16, function(err, salt){
        if(err){ throw err; }
        self.salt = salt.toString('hex');
    });

    crypto.pbkdf2(password, this.salt, 1000, 64, function(err, hash){
        if(err){ throw err;}
        self.hash = hash.toString('hex');
    });
};
UserSchema.methods.validatePassword = new function(password){
    var hash = crypto.pbkdf2Sync(password, this.salt, 1000, 64).toString('hex');
    return this.hash = hash;
};

我知道已经晚了，但是如果有人仍然面临这个问题，这就是我所做的，它解决了我的问题。

UserSchema.methods.setPassword = function(password){
    this.salt = crypto.randomBytes(16).toString('hex');
    this.hash = crypto.pbkdf2Sync(password, this.salt, 1000, 64).toString('hex');
}

UserSchema.methods.validatePassword = function(password){
    var hash = crypto.pbkdf2Sync(password, this.salt, 1000, 64).toString('hex');
    return this.hash === hash;
};
