🤔 What Is A JWT Decoder?
Think of a JWT token as a sealed envelope with a secret message - that's secure authentication data! Our decoder opens and validates these tokens instantly, showing you the hidden payload and verifying signatures with RS256, HS256, and more. Understand web security tokens like a developer, no cryptography degree needed!
