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 🙏

| 主题 | 目录 | 说明 | Ruby | JavaScript | |------|------|------|------|------------| | stego | stego/ | Unicode 同形字符隐写:Claude Code 风格日期/撇号隐蔽通道、通用 5 通道隐写 | lib/ccc/stego_encoder.rb, lib/ccc/unicode_stego.rb | src/ | | desensitize | desensitize/ | 全方位数据脱敏:FPE、令牌化、Paillier 同态加密、日期偏移、差分隐私、假名化、零知识承诺、k-匿名泛化 | lib/ccc/desensitizer.rb | src/desensitizer.js |

快速开始(desensitize 主题)

Ruby:

require "ccc/desensitizer"

engine = Desensitizer::Engine.new(secret_key: "your-master-key")
engine.field :phone,   :fpe
engine.field :salary,  :paillier
engine.field :name,    :pseudonymize

safe  = engine.desensitize(raw_record)   # 脱敏后安全送 AI
back  = engine.restore(safe)             # AI 返回后还原

JavaScript(Node.js ≥ 14,大数运算使用原生 BigInt,与 Ruby 版跨语言一致):

const { Desensitizer } = require("ccc"); // 或 require("ccc/src/desensitizer")

const engine = new Desensitizer.Engine({ secretKey: "your-master-key" });
engine.field("phone", "fpe");
engine.field("salary", "paillier");   // 密文为 BigInt
engine.field("name", "pseudonymize");

const safe = engine.desensitize(rawRecord); // 脱敏后安全送 AI
const back = engine.restore(safe);          // AI 返回后还原

开发

bundle exec rake spec   # 运行全部 Ruby 测试
bundle exec rake demo   # 运行全部 Ruby 演示
npm test                # 运行全部 JS 测试(node --test spec/js/*.test.js)
npm run build           # rollup 构建 dist/(ESM / CJS / UMD)
