FAQ

Is Base64 encryption?

No. Base64 is an encoding format, not encryption.

Does the JWT decoder verify signatures?

It decodes header and payload locally. Signature trust must be verified with the correct key in your own environment.

Are files uploaded for hash generation?

No. Hash generation runs locally in the browser.
