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 🙏

JSSM4

一个 SM4 加解密 JavaScript 实现

解决了大多数 js 实现中循环左移位数丢失问题

100w次加解密耗时:

加密100w耗时: 5222.376ms
解密100w耗时: 8622.148ms

使用

//  <script src="./path/to/jssm4.min.js"></script>
// or const JSSM4 = require("jssm4");

var sKey = "qawsedrftgyhujik";
var sm4 = new JSSM4(sKey);

["ABC", "abc", "ABCabc", "ABC123", "abc123", "123", "你好吗"].map(
  (text) => {
    console.log("原文:", text);
    console.time("加密耗时");
    var endata = sm4.encryptData_ECB(text);
    console.timeEnd("加密耗时");
    console.log("密文:", endata);
    console.time("解密耗时");
    var dedata = sm4.decryptData_ECB(endata);
    console.timeEnd("解密耗时");
    console.log("解密:", dedata);
    console.log("-----------");
  }
);
