passwordmanagement

一个纯前端的随机密码 / API Token / UUID 生成器，部署在 Cloudflare Workers 静态资源（Workers Assets）上。所有随机数都在浏览器本地通过 crypto.getRandomValues() 与 crypto.randomUUID() 生成，不会上传任何数据。

功能

• 密码生成
  • 长度 3–64，滑块 + 数字框双向同步
  • 小写 / 大写 / 数字 / 特殊符号四类，至少选 1 类，强制每类至少出现一次后 Fisher–Yates 洗牌
  • 可选「排除易混淆字符」（0 O o 1 l I `）
  • 实时 Shannon 熵密码强度条（弱 / 一般 / 强 / 非常强）
  • 一键显示 / 隐藏密码
• API Token：16 / 32 / 64 字节随机 hex
• UUID：v4，优先调用 crypto.randomUUID()，否则手动设置 version / variant 位
• 一键复制（优先 navigator.clipboard，回落到 execCommand）；隐藏状态下复制不会泄露
• 拒绝采样保证字符分布无偏，规避 % n 取模偏置
• 移动端响应式布局，支持键盘快捷键（回车重新生成）
• 单文件 HTML，零依赖、零追踪、零外部资源（仅一份 Google Fonts CSS）

本地开发

npm install
npx wrangler dev

部署

npx wrangler deploy

wrangler.toml 里已经配置好自定义域作为 Workers 路由。Cloudflare 会自动在 zone 上创建 DNS 记录并签 SSL 证书。要换成自己的域名，把 wrangler.toml 里的 routes 改掉即可（zone 必须在同一个 Cloudflare 账号下）。

passwordmanagement (English)

A zero-dependency, fully client-side generator for random passwords, API tokens, and UUIDs, deployed on Cloudflare Workers Assets. Every random value is produced locally in the browser via crypto.getRandomValues() and crypto.randomUUID() — nothing is ever sent to a server.

Features

• Password generator
  • Length 3–64, range slider and number input kept in sync
  • Four character classes (lowercase / uppercase / digits / symbols); at least one must be selected, with one of each guaranteed before a Fisher–Yates shuffle
  • Optional "exclude ambiguous characters" filter (0 O o 1 l I `)
  • Real-time Shannon-entropy strength meter (weak / fair / strong / very strong)
  • Show / hide password toggle
• API token: 16 / 32 / 64 random bytes encoded as hex
• UUID: v4 via crypto.randomUUID(), with a manual fallback that sets the version and variant bits explicitly
• One-click copy (prefers navigator.clipboard, falls back to execCommand); copying a hidden password never reveals it
• Rejection sampling for unbiased character selection — no % n modulo bias
• Responsive layout for mobile; press Enter anywhere to regenerate the password
• Single HTML file, no dependencies, no tracking, no third-party assets aside from a single Google Fonts stylesheet

Local development

npm install
npx wrangler dev

Deploy

npx wrangler deploy

The wrangler.toml file already wires up a custom domain as the Worker's route. Cloudflare creates the DNS record and provisions the SSL certificate automatically. To use your own domain, edit the routes entry in wrangler.toml (the zone must live in the same Cloudflare account).
