Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

SM2 SM4 数据加、解密

安装

 npm i qh-tools

引入

import DataEncryption from "qh-tools/dist/dataEncryption.js";

使用

1、实例化

/**
 * SM2PublicKey { string } sm2公钥
 * SM2Privatekey { string } sm2私钥
 */
const dataEncryption = new DataEncryption(SM2PublicKey, SM2Privatekey);

2、获取 SM4 秘钥

/**
 * SM4HexKey { string } 将生成的 16 位随机字符串,转换为 16 进制字符串
 * SM4Encryption { string } sm2 公钥加密后的 sm4 秘钥
 */
const { SM4HexKey, SM4Encryption } = dataEncryption.generateSM4Key();

3、加密数据

/**
 * requestData { object } 需要加密的数据对象
 * SM4HexKey { string } 上一步获取的 sm4 16进制字符串
 * return { string } 加密后的字符串
 */
const data = dataEncryption.encrypt(requestData, SM4HexKey);

4、将加密后的数据和 sm4 秘钥传给后端

// 目前测试验证时 sm4 秘钥放在了请求头 (具体秘钥放在哪 需跟后端沟通)
config.headers["encryptkey"] = SM4Encryption;

// 加密后的数据 替换到原有位置
// 例 post 请求
config.data = dataEncryption.encrypt(requestData, SM4HexKey);

// 例 get 请求
config.params = dataEncryption.encrypt(requestData, SM4HexKey);

5、数据解密

// 获取到后端返回的 sm4 秘钥 (具体后端返回的秘钥放在哪个字段 需跟后端沟通)
const SM4PrivateKey = res.headers["encryptkey"];

/**
 * responseData { object } 需要解密的数据对象
 * sm4PrivateKey { string } 后端返回的 sm4 秘钥, 测试验证实例中 将返回的 sm4 秘钥进行了截取处理 (是否处理 需要与后端沟通)
 * return { object } 解密后的数据对象
 */
const data = dataEncryption.decrypt(responseData, sm4PrivateKey);
