About this app

SecurityV2 lets you create personalized encryption recipes with your friends and groups — then encrypt text and hide it inside images using steganography. Send through WhatsApp,
Telegram, email, or any platform. Only someone with the same recipe can reveal it.

HOW IT WORKS
1. Add a friend or create a group
2. Create a custom encryption recipe together (secret word, magic number, mixing pattern, secret emoji)
3. Type your message and tap Encrypt
4. The app hides your encrypted message inside a generated image
5. Share the image — it looks completely normal but contains your secret
6. Your friend opens the image in SecurityV2 and decrypts it instantly

STEGANOGRAPHY — HIDE IN PLAIN SIGHT
Your encrypted message is embedded inside a PNG image using LSB steganography. To everyone else, it's just a picture. Only your friend with SecurityV2 and the right recipe can
extract and decrypt the hidden message.

COLLABORATIVE RECIPES
Create recipes together with your friend — the app randomly assigns ingredients to each person, so nobody knows the full recipe. Not even you.

YOUR CIPHER, YOUR RULES
Unlike other encryption tools, SecurityV2 lets you customize HOW your messages are encrypted. Each recipe is unique — combining your secret ingredients into a one-of-a-kind
encryption algorithm.
