# DTB - Daily Tool Box > Every new tab becomes a developer’s tool box: Base64, JSON format/validate, JWT decode & verify, MD5/SHA hashes, and Unix timestamp conversion — plus a clock and your IP. All local, offline, no data leaves your browser.

Instead of searching for random online converters that upload your data, open a new tab and your most-used dev tools are right there — running entirely inside Firefox, offline, with nothing sent to any server. What’s inside: • Base64 — encode and decode text, UTF-8 safe (emoji, accents, CJK). URL-safe mode, live conversion, copy / clear / swap. • JSON — format, minify, and validate, with the exact line and column shown for invalid input. • JWT — decode a token’s header and payload, see iat / exp / nbf as human-readable dates and expiry status, and verify HS256/384/512 signatures with your secret. • Hash — MD5, SHA-1, SHA-256 and SHA-512 digests computed live, with an uppercase toggle and one-click copy. • Timestamp — the live current Unix time plus two-way conversion between epoch and human dates, with automatic seconds / milliseconds detection. Also on the page: a clean clock and your public IP address (click to copy). Why DTB: • Private by design — every tool runs locally. Your text, tokens, and secrets never leave your machine. • Fast — no page loads, no ads, no sign-in. • Extensible — built as a “tool factory,” so new tools are added cleanly over time. • Theme-aware — matches your system light or dark mode.
