ShadowB is an all-in-one Python toolkit that bundles a wide range of everyday utilities — system info, image steganography, temporary email, QR codes, CAPTCHA generation, password tools, file safety checks, and more — into a single, easy-to-import package, 100% open source. No telemetry, no analytics, no external server. Every function runs locally on the user's own machine — nothing is collected or transmitted by the library's maintainers.
