JWT Is Not Encrypted (And That's By Design)
📰 Dev.to · Neural Download
Understand why JWT is not encrypted and how its security relies on signatures, not encryption
Action Steps
- Inspect a JWT token to see its plain text payload
- Learn about the alg:none attack and its implications on JWT security
- Implement secure practices for handling and verifying JWT signatures
- Use a secure algorithm for signing JWTs, such as RS256 or ES256
- Test JWT implementation for vulnerabilities, including the alg:none attack
Who Needs to Know This
Developers and security engineers benefit from understanding JWT's design to ensure secure implementation in their applications
Key Insight
💡 JWT security relies on the integrity of the signature, not the encryption of the payload
