When do you need a Security tool?

Security tools on ToolsPack cover the most common authentication and cryptography tasks developers encounter. The JWT Decoder decodes a JSON Web Token's header and payload without verifying the signature — useful for quickly inspecting what claims a token contains during development or debugging. Importantly, no token you paste is sent to a server; the decoding happens entirely in JavaScript.

The Password Generator creates cryptographically random passwords using the browser's built-in crypto.getRandomValues() API, not a predictable random number generator. The Hash Generator supports MD5, SHA-1, SHA-256, and SHA-512 — useful for verifying file integrity or generating comparison hashes without leaving your browser.
