Everyday developer utilities: RFC 4122 UUIDs, JWT payload inspection, SHA-256 hashes, cron explanations, and Unix epoch conversion. Secrets you paste are not sent to Answer to Geek servers.
The JWT decoder reads the header and payload only — it does not verify signatures and does not need your secret. Cron parser turns a five-field expression into plain English. Use the hash generator for checksums, not as a password locker.
