Question

我是nodejs，sails的新手，需要在将数据存储到数据库之前对其进行加密。

我找到了模块simplecrypt

并制作了此代码演示。

var simplecrypt = require("simplecrypt");

var sc = simplecrypt();
var digest = sc.encrypt("my secret");
console.log(digest); // "66cea6eb1c18b8862485cf0604fa6062" 

var message = sc.decrypt(digest);
console.log(message); // "my secret"

它会对值进行加密，但是当我尝试解密时，我收到错误：

crypto.js:202 
    var ret = this._handle.final();
                          ^
Error: error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad decrypt
    at Error (native)
    at Decipher.Cipher.final (crypto.js:202:26)

有人可以建议我正确解密我的加密值吗？

花了一整天的时间来检查后，我把结果搞清楚了。我必须定义

func mergeChanges(notification: NSNotification) {
    NSLog("mergeChanges notif:\(notification)")
    if let moc = managedObjectContext {
        moc.performBlock {
            moc.mergeChangesFromContextDidSaveNotification(notification)
            self.postRefetchDatabaseNotification()
        }
    }
    let vc = CollectionViewController()
    let view = self.window?.rootViewController

    vc.title = "Syncing"
    view?.title = "Syncing"
}

func persistentStoreDidImportUbiquitousContentChanges(notification: NSNotification) {
    self.mergeChanges(notification);
}

func storesWillChange(notification: NSNotification) {
    NSLog("storesWillChange notif:\(notification)");
    if let moc = self.managedObjectContext {
        moc.performBlockAndWait {
            var error: NSError? = nil;
            if moc.hasChanges && !moc.save(&error) {
                NSLog("Save error: \(error)");
            } else {
                // drop any managed objects
            }

            moc.reset();
        }

       let vc = CollectionViewController()
       vc.title = "Syncing"

        // reset UI to be prepared for a totally different
        // don't load any new data yet.
    }
}

func storesDidChange(notification: NSNotification) {
    // here is when you can refresh your UI and
    // load new data from the new store
    let vc = CollectionViewController()
    // vc.collectionView.reloadData()

    NSLog("storesDidChange posting notif");
    self.postRefetchDatabaseNotification();
}

并将值从mydabase赋值给user1并声明

var user1 ={
  method:methodinput,
  password:passwordinput,
  salt:saltinput
};

然后将user.password与passEncrypt进行比较。

根据你的评论@angel，我想我明白你的问题在哪里。 decrypt（）接受String的散列，而不是String（user.password）本身。

var simplecrypt = require("simplecrypt");
var sc = simplecrypt();

var user = {
  password: "password123"
};

var myHash = sc.encrypt(user.password);

// myHash returns a hash of user.password

console.log(myHash); // "66cea6eb1c18b8862485cf0604fa6062" 

// This next state
// You will need to pass the created hash into decrypt
var message = sc.decrypt("66cea6eb1c18b8862485cf0604fa6062");
console.log(message); // "password123"

如果您尝试验证用户已登录（假设来自user.password），您可能希望将密码与数据库中存储的哈希值进行比较。

// Here is a simple example for a login screen
// (Not for use in production)
var simplecrypt = require("simplecrypt");
var sc = simplecrypt();

var user = {
  password: "password123"
};

// This would be stored in the DB
var databaseHash = sc.encrypt(user.password);

// Here is your login function
//
// Now when the user logs in, you will compare the two
// and see if the credentials match
var userInput = sc.encrypt(user.password);
var usersPasswordFromDatabase = databaseHash;

if (userInput === usersPasswordFromDatabase){
  // Logged In!
  console.log('Logged In!');
}else {
  console.log('Invalid Username/Password');
}

该示例将返回＆＃39;已登录＆＃39;

使用simplecrypt解密错误
