在Node环境如何实现非对称加密

最近在使用strapi5开发接口API文档，徐需要做一个非对称加密，记录下一种简单的生成方式

生成 RSA 私钥、公钥对

执行命令

openssl genrsa -out private.pem 1024

查看私钥 cat private.pem

执行命令，根据私钥生成公钥

openssl rsa -in private.pem -pubout -out public.pem

加密代码

const crypto = require('crypto')  
  
const {publicKey, privateKey} = require('./config');  
    const rsaEncrypt = (str) => {  
    return crypto.publicEncrypt(publicKey, str).toString('hex');  
}  
  
const rsaDecrypt = (str) => {  
    return crypto.privateDecrypt(privateKey, Buffer.from(str, 'hex')).toString();  
}  
  
module.exports = {  
    rsaDecrypt,  
    rsaEncrypt  
}

挂在全局

在strapi的入口文件

'use strict';  
const utils = require('./helpers/utils') // 扩展工具  
// const services = require("./server/services");  
// console.log(services)  
module.exports = {  
/**  
* An asynchronous register function that runs before  
* your application is initialized.  
*  
* This gives you an opportunity to extend code.  
*/  
register({strapi}) {  
    strapi.$utils = utils  
},  
  
/**  
* An asynchronous bootstrap function that runs before  
* your application gets started.  
*  
* This gives you an opportunity to set up your data model,  
* run jobs, or perform some special logic.  
*/  
bootstrap(/*{ strapi }*/) {  
},  
};
