Domain Overview

How Security & Privacy Work

Provide cryptographically secure password generation, SSH key generation, PGP key viewing/creation, hash generation/verification, JWT inspection, entropy calculation, and local file encryption.

By executing processing routines directly inside your web browser using client-side JavaScript, WebWorkers, and WebAssembly, tools process tasks without waiting for remote server queues or external APIs.

Core Processing Standards

Browser Processing: Files and inputs are processed locally in your browser.
Off-Main-Thread Execution: Heavy transformations process in background workers to keep UI smooth and responsive.
Offline Capability: Core tool functions operate directly in your browser without an active internet connection.
