Decoding JWT Tokens from the Command Line

When working with JSON Web Tokens (JWTs), it's essential to be able to decode them to extract their contents. In this post, we'll explore two popular methods for decoding JWTs from the command line: jwt-cli and Python's jwt library.

jwt-cli is a simple, command-line tool that allows you to decode JWTs with ease. To get started, install jwt-cli using pip: pip install jwt-cli. Once installed, you can decode a JWT by running jwt-cli decode --key your_private_key --token your_jwt_token. Replace your_private_key and your_jwt_token with your actual key and token values.

For a more in-depth solution, you can use Python's jwt library. First, install the library using pip: pip install PyJWT. Then, import the library and decode your JWT like so: import jwt; print(jwt.decode(token='your_jwt_token', key='your_private_key')). Again, replace your_private_key and your_jwt_token with your actual key and token values.

When decoding JWTs, it's crucial to keep your private key secure to prevent unauthorized access to your tokens. IAMDevBox.com offers expert advice on securing your JWTs and improving your overall security posture.
