前言
C#后端动态生成RSA公钥和私钥， Vue前端使用公钥对数据加密，后端使用私钥解密
vue前端
1.安装依赖
npm install jsencrypt --save
2.创建rsa.js文件 引用依赖
import { JSEncrypt } from 'jsencrypt'
//加密
//str 未加密字符串
export function setEncrypt(str){
//实例化JSEncrypt
let jse = new JSEncrypt();
//加密公钥（由C#后端生成）
let PUBLIC_KEY = `MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAvnuBHhh9/Mwi4Z8Ea2IfVc7SJYyKkJT+4m4LBJbgxRVPa+ej1iAvJAJ++1CNfH6oVr6tw/wqEIZybTG7+iPm7SzfoW9eb/LYsLR43zLqriYWy7qAd7S/13zILiAGLUy/h9CDYwoXYaNXanVGe0iJb+NXmg7f4MAEo7rR15QHQ8zDtomPI/Fz9vz+o/xzHqsLVnxZIpn4dlCp+7QtzOePnvEda5xqWk4DNaVV2fr9gwfBFd8MyAP+CyBXLAWpmxinRU6knsLKAlqcbOLNjk2+aPNvH9EWHODKWBuMPpdDwQexD+V3/nOp8c07NzSfwXmlZuRKod9SqVY88Pg1r84WwQIDAQAB`
jse.setPublicKey('-----BEGIN PUBLIC KEY-----' + PUBLIC_KEY + '-----END PUBLIC KEY-----');
let data = jse.encrypt(str.toString()); // 进行加密
return data;
}
//解密
//params 待解密字符串
export function getDecrypt(params){
//实例化JSEncrypt
let jse = new JSEncrypt();
//使用前端私钥解密（私钥由C#后端生成）

3.创建test.vue文件使用加密和解密
测试

C#后端
1.生成公钥和私钥
class Program {
static void Main(string[] args) {
Console.WriteLine("---------------------------------------------------------");
Console.WriteLine("◆◆◆◆◆◆◆◆◆◆◆◆ RSA测试 ◆◆◆◆◆◆◆◆◆◆◆◆");
Console.WriteLine("---------------------------------------------------------");
CreateRsa();
Console.WriteLine("-------------------------------------------------------------");
Console.WriteLine("◆◆◆◆◆◆◆◆◆◆◆◆ 回车退出... ◆◆◆◆◆◆◆◆◆◆◆◆");
Console.WriteLine();
Console.ReadLine();
}
static void CreateRsa()
{
//指定密钥大小创建一个新的RSA
var rsa = new RSA(1024);
Console.WriteLine("【" + rsa.KeySize + "私钥（PKCS#1）】：");
Console.WriteLine(rsa.ToPEM().ToPEM_PKCS1());
Console.WriteLine();
Console.WriteLine("【" + rsa.KeySize + "公钥（PKCS#8）】：");
Console.WriteLine(rsa.ToPEM().ToPEM_PKCS8(true));
Console.WriteLine();
}
}
