JWT Toolkit
Zero-dependency JWT decoder and inspector. Decodes any JWT token and shows header, payload claims, algorithm info, expiry status, and signature details.
Quick Start
# Decode a JWT token
python3 scripts/jwt_decode.py eyJhbGciOiJIUzI1NiIs...
# Read token from file
python3 scripts/jwt_decode.py --file token.txt
# Read from stdin (pipe from curl, etc.)
echo "eyJ..." | python3 scripts/jwt_decode.py --stdin
# JSON output for scripting
python3 scripts/jwt_decode.py eyJ... --format json
# Also handles "Bearer " prefix automatically
python3 scripts/jwt_decode.py "Bearer eyJhbGciOiJIUzI1NiIs..."
Features
- Decodes header and payload with human-readable claim labels
- Shows algorithm details and security warnings (e.g.,
nonealgorithm) - Checks token expiry with remaining time or time-since-expired
- Recognizes 20+ standard and common claims (iss, sub, aud, roles, scope, etc.)
- Strips "Bearer " prefix automatically
- JSON and text output formats
- No external dependencies — pure Python stdlib
