Frequently asked questions
Does decoding a JWT verify its signature?
Decoding reveals the token structure but does not automatically prove that its signature is valid or trustworthy.
Can a hash be reversed?
Cryptographic hashes are designed to be one-way. Weak or predictable source values may still be discovered through guessing or lookup attacks.
