RSA,RSA2公钥私钥加密解密
支付宝在线加密：强烈推荐不报错！
初始配置
1、阿里文档
下载工具包：
2、进行安装后点击生成秘钥即可
一、vue项目使用
引入
npm install jsencrypt
import JSEncrypt from 'jsencrypt/bin/jsencrypt.min' // 密钥对生成 http://web.chacuo.net/netrsakeypair const publicKey = 'MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAKoR8mX0rGKLqzcWmOzbfj64K8ZIgOdH\n' + 'nzkXSOVOZbFu/TJhZ7rFAN+eaGkl3C4buccQd/EjEsj9ir7ijT7h96MCAwEAAQ==' const privateKey = 'MIIBVAIBADANBgkqhkiG9w0BAQEFAASCAT4wggE6AgEAAkEAqhHyZfSsYourNxaY\n' + '7Nt+PrgrxkiA50efORdI5U5lsW79MmFnusUA355oaSXcLhu5xxB38SMSyP2KvuKN\n' + 'PuH3owIDAQABAkAfoiLyL+Z4lf4Myxk6xUDgLaWGximj20CUf+5BKKnlrK+Ed8gA\n' + 'kM0HqoTt2UZwA5E2MzS4EI2gjfQhz5X28uqxAiEA3wNFxfrCZlSZHb0gn2zDpWow\n' + 'cSxQAgiCstxGUoOqlW8CIQDDOerGKH5OmCJ4Z21v+F25WaHYPxCFMvwxpcw99Ecv\n' + 'DQIgIdhDTIqD2jfYjPTY8Jj3EDGPbH2HHuffvflECt3Ek60CIQCFRlCkHpi7hthh\n' + 'YhovyloRYsM+IS9h/0BzlEAuO0ktMQIgSPT3aFAgJYwKpqRYKlLDVcflZFCKY7u3\n' + 'UP8iWi1Qw0Y=' // 加密 export function encrypt(txt) { const encryptor = new JSEncrypt() encryptor.setPublicKey(publicKey) // 设置公钥 return encryptor.encrypt(txt) // 对数据进行加密 } // 解密 export function decrypt(txt) { const encryptor = new JSEncrypt() encryptor.setPrivateKey(privateKey) // 设置私钥 return encryptor.decrypt(txt) // 对数据进行解密 }
使用
import { encrypt, decrypt } from '@/utils/jsencrypt.js' test () { console.log('密码：123456') const num = encrypt('123456') console.log('加密后：' + num) console.log('解密后：' + decrypt(num)) },
二、Springboot集成

快速使用
实际使用：
//2、非对称解密密码 try { loginBody.setPassword(RsaUtil.decryptByPrivateKey(loginBody.getPassword())); } catch (Exception e) { throw new ServiceException("请不要尝试篡改密码！"); }
测试：
public static void main(String[] args) throws Exception{ String password = "changlu"; //使用公钥加密 String encryptPassword = encryptByPublicKey(RsaUtil.publicKey, password); //传入加密过后的密码进行解密 String decodePassword = decryptByPrivateKey(encryptPassword); System.out.println(decodePassword); }
