📖 What is JWT?

JSON Web Tokens are compact, self-contained tokens for secure information exchange.

They consist of three parts: Header, Payload, and Signature.

🔧 JWT Structure

• Header - Algorithm and token type
• Payload - Claims (user data, expiry)
• Signature - Verification hash

💡 Tips

→ JWTs are not encrypted, just signed
→ Check expiry (exp) and issued at (iat)
→ Signature not verified here (decode only)
