Frequently asked questions
Does JWT decoding validate the signature?
No. It only displays header and payload. Validation requires the secret/public key and backend libraries.
Which hash algorithms are available?
It depends on the tool, but the goal is to cover common options used for comparisons and integrity checks.
Is my token or text sent to a server?
The intent is local browser processing. If any tool changes that behavior, it will be clearly stated on its page.
Validate and debug with security utilities
In development, you often verify integrity with hashes or inspect JWT tokens while debugging. These tools help you do that faster.
Reminder: decoding a JWT does not validate its signature. Use it for inspection, not as a security check.
