Dev Tools has five small helpers: flat JSON to CSV and back, a SQL keyword formatter, a JavaScript regex tester, Base64 encode and decode, and SHA-1, SHA-256, SHA-384, and SHA-512 hashes through Web Crypto. Everything runs in this tab. The text is not posted to a FileTools Kit server. Base64 is encoding, not a lock.
Use a hash to compare a line you already have, not as a password store. This page does not offer MD5. Do not paste a live password on a shared screen.
The result is hex you can copy. A reload clears the box. Operator: Souren Das, Bengaluru.
