如何使用RSA在javascript中加密并在php中解密 [英] How to encrypt in javascript and decrypt in php using RSA

问题描述

我使用< a href =https://www.pidder.de/pidcrypt/?page=rsa> pidcrypt-rsa< / a>加密客户端的数据用公钥。我想使用php在服务器端解密它，我使用< a href =http://phpseclib.sourceforge.net/rsa/examples.html#convert> phpseclib< / a>用于服务器端解密。 
客户端js代码：

 功能加密（值）{
 
  var  public_key = '  ----- BEGIN PUBLIC KEY ----- \\\
\ 
 MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCqGKukO1De7zhZj6 + H0qtjTkVxwTCpvKe4eCZ0\\\

\ 
 3J + skZ6UtW + 5u09lHNsj6tQ51s1SPrCBkedbNf0Tp0GbMJDyR4e9T04ZZwIDAQAB \ n\ 
 ----- END PUBLIC KEY -----'; 
 params = certParser（public_key）; 
  if （params.b64）{
  var  key = pidCryptUtil.decodeBase64（ params.b64）; 
  //  新的RSA实例 
  var  rsa =  new  pidCrypt.RSA（）; 
  //   RSA加密 
  //   ASN1解析 
  var  asn = pidCrypt.ASN1.decode（pidCryptUtil .toByteArray（键））; 
  var  tree = asn.toHexTree（）; 
  //  设置加密公钥 
 rsa.setPublicKeyFromASN（tree） ; 
 
 crypted = rsa.encrypt（value）; 
 
  return  pidCryptUtil.fragment（pidCryptUtil.encodeBase64（pidCryptUtil.convertFromHex（crypted））， 64 ）; 
} 
 返回 ' 错误; 
} 

服务器端代码：

 <？php

  $ rsa  =  new  Crypt_RSA（）;

  $ de  = $ rsa-> decrypt（base64_decode（$ name））; 
  echo   $ de ;

但它没有回应任何东西！

我做错了什么？

解决方案

rsa-> LOADKEY（

I encrypt data in client side using <a href="https://www.pidder.de/pidcrypt/?page=rsa">pidcrypt-rsa</a> with public key. I want to decrypt it in server side using php, I use <a href="http://phpseclib.sourceforge.net/rsa/examples.html#convert">phpseclib</a> for server side decrypting.
client side js code:

function Encrypt(value) {
	
		var public_key  = '-----BEGIN PUBLIC KEY-----\n\

		params = certParser(public_key);
        if(params.b64){
        var key = pidCryptUtil.decodeBase64(params.b64);
        //new RSA instance
        var rsa = new pidCrypt.RSA();
        //RSA encryption
        //ASN1 parsing
        var asn = pidCrypt.ASN1.decode(pidCryptUtil.toByteArray(key));
        var tree = asn.toHexTree();
        //setting the public key for encryption
        rsa.setPublicKeyFromASN(tree);
        
        crypted = rsa.encrypt(value);
		
        return pidCryptUtil.fragment(pidCryptUtil.encodeBase64(pidCryptUtil.convertFromHex(crypted)),64);
		}
		return 'error';
		}

server side code:

but it didn't echo any thing!
what I do wrong?

rsa = new Crypt_RSA();
