有角度的RSA库 [英] RSA library with angular

问题描述

你好，我试图在我的应用程序中实现加密。我使用角（角-4）作为前端，节点js用于后端。通过socket.io通过自定义命令进行通信。但是基本上我坚持的是在客户端找到一个适用于RSA加密的库。客户端将首先请求服务器进行RSA公钥。服务器响应密钥，但现在我找不到任何适合使用RSA加密数据的库。我试过了node-rsa。以下是来自'node-rsa'的代码sn

  import *作为NodeRSA; 
 
 @Injectable（）
 
 export class SecurityService {
 RSA：any 
 initializeRSA（key：string）{
 this.RSA =新的NodeRSA（）; 
 this.RSA.importKey（key）
 console.log（this.RSA.encrypt（'Hello World'））; 
} 
  

但我收到此错误。

 加密时出错。原始错误：TypeError：crypt.createHash不是一个函数
在NodeRSA.webpackJsonp ... / .. / .. / .. / node-rsa / src / NodeRSA.js.module.exports.NodeRSA $ $ encrypt 
  

帮助将非常感激。

实现

在Angular Project的资产文件夹中添加JSEncrypt Lib javascript文件。
在 index.html中添加脚本

< script src = jsencrypt.js>< / script>

所以，它可以在所有的组件。

在要使用它的组件文件中声明JSEncrypt。

declare var JSEncrypt：any;

Inside类声明变量

decrypt = new JSEncrypt（）;

const privatekey =私钥在这里;

const publickey =公钥去这里;

const decryptDataRow = Decreted data string;

this.decrypt.setPrivateKey（privatekey）;

this.decryptdata = this.decrypt.decrypt（decryptDataRow）;

decryptdata conation result string

Hello I am trying to implement encryption in my application. I am using angular (angular-4) for the frontend and node js for the backend. Communication is done through socket.io through custom commands. But basically what I am stuck at is finding an appropriate library for RSA encryption in client side. client will first request server for an RSA public key. Server responds with key but now I cannot find any library suitable to encrypt data with RSA using this public key. I have tried node-rsa. Following is a code sn

import * as NodeRSA from 'node-rsa';

@Injectable()

export class SecurityService {
    RSA: any
    initializeRSA(key: string) {
        this.RSA = new NodeRSA();
        this.RSA.importKey(key)
        console.log(this.RSA.encrypt('Hello World'));
    }

But I am receiving this error.

Error during encryption. Original error: TypeError: crypt.createHash is not a function
at NodeRSA.webpackJsonp.../../../../node-rsa/src/NodeRSA.js.module.exports.NodeRSA.$$encrypt

Help would be very much appreciated.

I have used JSEncrypt v2.3.0 Lib for same.

Implementation

Add JSEncrypt Lib javascript file in Asset Folder of Angular Project. Add script in index.html

<script src="jsencrypt.js"></script>

So, It will available at all Component.

declare JSEncrypt at your component file where you want to use it.

declare var JSEncrypt: any;

Inside class declare variable

decrypt = new JSEncrypt();

const privatekey = Private Key goes here;

const publickey = Public key goes here;

const decryptDataRow = Decreted data string;

this.decrypt.setPrivateKey(privatekey);

this.decryptdata = this.decrypt.decrypt(decryptDataRow);

decryptdata conation result string
