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 🙏

A Simple Pure JavaScript GM-Standards SM2/SM3/SM4 Implementation based on sjcl.

扩展sjcl实现的优势在于其丰富的对称加密模式实现,以及其简洁的代码、较好的性能。“缺点”在于其缺乏CSR、CERT等高级功能支持。您也可以参考另外一个实现:jsrsasign-sm

SM2

  • 加解密
  • 签名、验签
  • 密钥交换

具体使用方法,请参考sm2_test.js

公私钥处理

  • PKIX EC公钥解析、构造
  • SEC1 EC私钥解析、构造
  • PKCS#8私钥解析、构造(不加密)
  • PKCS#8私钥解析、构造(加密)。支持PBES2/PBKDF2,HMAC HASH支持SHA1/SHA256/SHA512/SM3,加解密支持SM4/AES,加密模式支持CBC/GCM

SM3

位于sjcl.hash.sm3中,使用方式和其它哈希算法相同。具体使用方法,请参考sm3_test.js

SM4

位于sjcl.cipher.sm4中,使用方式和AES相同。具体使用方法,请参考sm4_test.js

如果是NodeJS的后端应用,请直接使用NodeJS提供的SM4实现(基于OpenSSL)。NodeJS目前尚未支持SM4-GCM模式,请参考一种使用nodejs SM4-ECB和sjcl gcm的SM4-GCM实现
