Question

我正在对用户名/密码使用加密和解密并将其保存在数据库中，同时我将其与Usertype一起使用，用户可以使用自己的面板登录。

注册时，Encrypt可以正常工作并保存在数据库中，但是当我尝试登录时，输入的密码不起作用。我认为解密无法调用我输入的密码，并且无法登录界面。

我正在使用System.Security.Cryptograph和System.IO。

类文件

var synth = window.speechSynthesis;

// get voices
var voices = synth.getVoices();

// when voices have finished loading
synth.onvoiceschanged = function() {

  var sayThis = new SpeechSynthesisUtterance('Hi how are you?');
  sayThis.onend = function(event) {
    console.log('SpeechSynthesisUtterance.onend');
  }

  sayThis.onerror = function(event) {
    console.error('SpeechSynthesisUtterance.onerror');
  }

  var selectedVoice = 'Google UK English Female';
  for (var i = 0; i < voices.length; i++) {
    if (voices[i].name === selectedVoice) {
      sayThis.voice = voices[i];
      break;
    }
  }
  sayThis.pitch = 1;
  sayThis.rate = 1;

  synth.speak(sayThis);
}

我得到的结果什么都没有。我一直按登录按钮，但仍然没有显示任何内容。由于密码已被加密，如何使用上面的登录代码解密密码？

Answer 1

与soohoonigan said一样，您应该加密键入的用户密码，并将其与数据库中存储的密码进行比较。

您不需要解密它。

Answer 2

是的，不要在屏幕级别解密密码。
使用屏幕和数据库中的加密密码进行比较。
如果登录正确，请提供消息。

使用登录名和用户类型加密/解密
