我正在使用 localStorage 存储数据并且我想加密密码，然后当密码在 localStorage 中加密时，我现在想解密它以便能够登录。我尝试加密工作但解密不工作，错误消息是： Uncaught SyntaxError: Unexpected end of input

我正在使用 CryptoJS v3.1.2 code.google.com/p/crypto-js

这里的代码：

var JsonFormatter = {
stringify: function (cipherParams) {
var jsonObj = {ct: cipherParams.ciphertext.toString(CryptoJS.enc.Base64)};
    if (cipherParams.iv) {jsonObj.iv = cipherParams.iv.toString();}
    if (cipherParams.salt) {jsonObj.s = cipherParams.salt.toString();}
    return JSON.stringify(jsonObj);
},
 parse: function (jsonStr) {
    var jsonObj = JSON.parse(jsonStr);
    var cipherParams = CryptoJS.lib.CipherParams.create({
        ciphertext: CryptoJS.enc.Base64.parse(jsonObj.ct)
    });
    if (jsonObj.iv) {cipherParams.iv = CryptoJS.enc.Hex.parse(jsonObj.iv)}
    if (jsonObj.s) {cipherParams.salt = CryptoJS.enc.Hex.parse(jsonObj.s)}
    return cipherParams;
}
};

加密.js

function btnSubmit(){

var p = document.getElementById("setpass").value;
if(p.length >= 5){

    var password = localStorage["Password"];
    var encoded = CryptoJS.AES.encrypt(JSON.stringify(p), password, {format: JsonFormatter}).ciphertext.toString();
    localStorage.setItem("Password", encoded);

    jAlert('Password is set', 'URIBlocker');
        window.location.reload();
}
else
{
    //Notification
} 
}

解密.js

function login() {

var usepass = document.getElementById('usepass').value;

var password = localStorage["Password"];
var encrypted = localStorage.getItem("Password");
var decrypted = CryptoJS.AES.decrypt(encrypted, password, {formatter: JsonFormatter}).toString();
var secret = JSON.parse(decrypted);


if (usepass === secret)
 {                          
    $('.bd_class').show();
    $('.go_class').hide();
 }
 else
 {
    $('.bd_class').hide();
    $('go_class').show();

}
}

出了点问题，我不知道错误是 Uncaught SyntaxError: Unexpected end of input
