如何从十六进制编码的模数创建一个RSA密钥，并在node.js中进行加密 [英] How to create an RSA key from hex-encoded modulus and encrypt in node.js

问题描述

我正在找到在node.js中RSA加密的方法，我想处理大数字，所以我使用这个：

解决方案

您应该能够以这种方式从模数和公共指数加载RSA公钥：

 code> var rsa = require（node-bignumber）; 
 
 VAR N = ad6eb61316ff805e9c94667ab04aa45aa3203eef71ba8c12afb353a5c7f11657e43f5ce4483d4e6eca46af6b3bde4981499014730d3b233420bf3ecd3287a2768da8bd401f0abd7a5a137d700f0c9d0574ef7ba91328e9a6b055820d03c98d56943139075d; 
 var e =010001; 
 var pub = new rsa.Key（）; 
 pub.setPublic（n，e）; 
 
 var message =Message; 
 var encrypted = pub.encrypt（message）; 
 
 console.log（加密）; 
  

RSA中的公钥包含模数和公共指数，因为加密期间需要两个值。

I'm finding the way to RSA encryption in node.js, I want to handle big numbers, so I use this: https://github.com/eschnou/node-bignumber

What I'm going to do is just encryption, with modulus and exponent. I don't have to do decryption. anyway, I got an error on and on, but I don't know what's wrong. Can anyone know what it is wrong? Thanks.

Code

require("node-bignumber");
var nvalue="ad6eb61316ff805e9c94667ab04aa45aa3203eef71ba8c12afb353a5c7f11657e43f5ce4483d4e6eca46af6b3bde4981499014730d3b233420bf3ecd3287a2768da8bd401f0abd7a5a137d700f0c9d0574ef7ba91328e9a6b055820d03c98d56943139075d";
var evalue="010001";
var encpw="";
var rsa = new RSAKey;

function encryptMessage() {
    var message = "All your bases are belong to us.";
    rsa.setPublic(evalue, nvalue);
    encpw.value = rsa.encrypt(message);
    console.log(encpw);
}

encryptMessage();

Error

解决方案

You should be able to load an RSA public key from modulus and public exponent in this way:

var rsa = require("node-bignumber");

var n = "ad6eb61316ff805e9c94667ab04aa45aa3203eef71ba8c12afb353a5c7f11657e43f5ce4483d4e6eca46af6b3bde4981499014730d3b233420bf3ecd3287a2768da8bd401f0abd7a5a137d700f0c9d0574ef7ba91328e9a6b055820d03c98d56943139075d";
var e = "010001";
var pub = new rsa.Key();
pub.setPublic(n, e);

var message = "Message";
var encrypted = pub.encrypt(message);

console.log(encrypted);

The public key in RSA consists of the modulus and the public exponent, because both values are needed during encryption.
