尝试使用私钥解密消息时出现node-rsa错误 [英] node-rsa errors when trying to decrypt message with private key
问题描述
所以我一直试图使用节点与节点rsa 和javascript与 jsencrypt 创建网站(用于作业),其中JavaScript客户端获取服务器生成的公钥( node-rsa)加密用户输入的消息(jsencrypt),将其发送到服务器,并让服务器对其进行解密(node-rsa)。密钥的生成工作,加密工作,然而解密不工作。当我启动节点脚本时,我为加密执行以下操作...
So I've been trying to use node with node-rsa and javascript with jsencrypt to create a website (for an assignment) where the javascript client gets the public key generated by the server (node-rsa), encrypts the message (jsencrypt) that the user has entered, sends it to the server and gets the server to decrypt it (node-rsa). The generation of the keys works, the encryption works however the decryption doesn't. When I start the node script I do the following for the encryption...
var NodeRSA = require('node-rsa');
var myDecrypter = new NodeRSA({b: 512});
当客户端请求密钥(我使用express)时,运行以下命令。
When the client requests the key (I am using express) the following is ran.
app.get('/getPublicKey', function(req, res){
var publicKeyJson = {"Key": ""};
console.log(myDecrypter.exportKey('public'));
publicKeyJson.Key = myDecrypter.exportKey('public');
res.json(JSON.stringify(publicKeyJson));
});
客户端然后像这样保存该密钥...
The client then saves that key like this...
var myEncrypter = new JSEncrypt();
var myJson = "";
$.getJSON( "getPublicKey", function( data ) {
myJson = JSON.parse(data).Key;
setKey();
});
function setKey() {
myEncrypter.setPublicKey(myJson);
}
当我在客户端加密并发送消息时,我这样做。 ..
When I got to encrypt and send the message on the client I do this...
function messageEncrypt() {
message = document.getElementById("message").value;
var encrypted = myEncrypter.encrypt(message);
myMessage = {"username": "", "userId": 0.0, "message": ""};
myMessage.username = me.username;
myMessage.userId = me.userId;
myMessage.message = encrypted;
console.log(encrypted);
$.post("sendMessage", myMessage);
}
当服务器收到消息时,这是发生了什么,错误。
When the server receives a message this is what happens, this is where I get the errors.
app.post('/sendMessage', function(req, res){
var message = req.body;
var user = message.username;
var id = message.userId;
console.log("What a mess, " + user + " said " + message.message + " what on earth does that mean");
//This line below errors
var clearMessage = myDecrypter.decrypt(message.message, 'utf8');
console.log(user + " said " + clearMessage);
});
我得到的错误是...
The error I get is ...
Error: Error during decryption (probably incorrect key). Original error: Error: error:040A1079:rsa routines:RSA_padding_check_PKCS1_OAEP_mgf1:oaep decoding error

有趣的是,当我使用了jsencrypt网站上的演示,并输入了我的私钥以及加密的邮件I获得正确的解密消息。
The interesting thing is that when I used the demo on jsencrypt website and enter my private key as well as the encrypted message I get the correct decrypted message.

So my question is...
我做错了什么节点rsa解密?
What am I doing wrong with my node-rsa decryption???

To answer your question @Curious_Programmer be default node-rsa uses pkcs1_oaep for encryption and decryption while jsencrypt uses pkcs1. Thankfully node lets you change the encryptionScheme, what you need to do is add ...
myDecrypter.setOptions({encryptionScheme: 'pkcs1'});
在
var myDecrypter = new NodeRSA({b: 512});
,所有都会像一个魅力,我希望我帮助你;)
and all will work like a charm, I hoped I helped you ;)
