Bu ilova haqida

Cipher Tools is a playful way to learn how encryption works. Type a message, pick a method, and watch it turn into secret text or a QR code — then decode it back.

WHAT YOU CAN DO
• Classical ciphers: Caesar, ROT13, Atbash, Playfair and Vigenère — the algorithms that shaped the history of cryptography.
• Modern encryption: AES-256 with a password of your choice.
• QR tools: create QR codes from any text, create password-protected QR codes that only open with the right password, and scan QR codes with your camera to decode them.
• Save the QR codes you create to your gallery and share them however you like.
• Clean dark interface, available in English, Arabic, Azerbaijani, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Portuguese, Russian, Spanish and Turkish.

PERFECT FOR
• Students and teachers exploring cryptography basics
• Puzzle and treasure-hunt creators
• Friends who want to exchange secret notes for fun

PRIVACY FIRST
Everything runs on your device, offline. The texts, keys and passwords you enter are never sent to a server and are never stored by us. No account is needed. The camera is used only to scan QR codes, and the gallery only to save the QR codes you create.

IMPORTANT NOTICE
This app is for education and entertainment only and is not a secure communication tool. Classical ciphers are easily broken, and the modern algorithms have not been independently audited. Do not use it to protect passwords, banking details or other information that must truly stay secret.

The app is free and supported by ads.
