Use Case Examples

JWT Debugging

Paste your JWT token:
eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c

Decoded:
Header: {"alg": "HS256", "typ": "JWT"}
Payload: {"sub": "1234567890", "name": "John Doe", "iat": 1516239022}

Cron Expression

Input: */15 9-17 * * 1-5
Output: "Every 15 minutes, between 09:00 and 17:59, Monday through Friday"
Next runs:
  - Mon Apr 10 09:00
  - Mon Apr 10 09:15
  - Mon Apr 10 09:30

Docker Run to Compose

# Input:
docker run -d --name myapp -p 8080:80 -v data:/app/data -e DB_HOST=localhost nginx:alpine

# Output:
services:
  myapp:
    image: nginx:alpine
    ports:
      - "8080:80"
    volumes:
      - data:/app/data
    environment:
      DB_HOST: localhost

IT Tools vs Alternatives

常见问题

Q: IT Tools 和 CyberChef 有什么区别？ A: CyberChef 更强大，支持操作链（将多个转换串联）和 300+ 操作，适合安全分析和复杂数据处理。IT Tools 更注重 UX 和日常开发工具，操作更直观。两者可以并存。

Q: 数据安全吗？ A: 所有工具在浏览器本地运行，数据不会发送到任何服务器。这是自托管 IT Tools 而非使用在线工具网站的主要优势。

Q: 可以添加自定义工具吗？ A: IT Tools 使用 Vue.js 构建，可以 fork 项目添加自定义工具。社区也在持续贡献新工具。
