JWT 签名

本地 JWT 签名思路，在浏览器本地生成签名 Token。

JWT Signer Tool

The JWT signer tool allows you to quickly generate a standard JSON Web Token locally in the browser by configuring the payload, algorithm, and secret key. The tool does not collect any sensitive data, ensuring a secure debugging process.

How do you use it?

  1. Enter the JWT payload (JSON format) in the payload area.
  2. Choose a supported signature algorithm (e.g., HS256, HS384, HS512).
  3. Enter the signature secret.
  4. The tool will immediately calculate and display the generated JWT locally.

Features

  • Browser-side local generation
  • Supports common HMAC algorithms
  • Completely offline, safe and reliable

Why use this tool?

  • Suitable for quickly generating JWTs during development and testing
  • Self-test without backend involvement
  • Ensures the security of private keys and payload data
