Security & Cryptography Tools
These tools help developers inspect authentication tokens and generate hashes for integrity checks. Decoding a JWT reveals its header and payload claims but does not verify its signature — a decoded token should never be treated as a validated one. Hash generators are provided for checksums and comparisons, not for password storage.
