StegoVault

Secure messaging, embedded in an image. StegoVault lets you send encrypted text, passwords, voice notes, and files to someone you trust by hiding them inside a picture. The recipient opens the file in StegoVault, enters the shared secret key, and unlocks your message. Without the key, the content stays completely unreadable.

How it works Write your secret message, record a voice note or attach files, and enter a secret key. StegoVault compresses and encrypts everything, then embeds the data invisibly into the pixels of a PNG image using steganography. Share it safely via WhatsApp, email, or cloud storage, and the recipient uses the same key to decrypt it.

Strong security under the hood All content is encrypted using AES-256-CBC with PBKDF2 key derivation, OS-level cryptographic random generation (CSPRNG), and an Encrypt-then-MAC (HMAC-SHA256) integrity check before it is embedded. If a single pixel is altered or the wrong key is entered, StegoVault immediately detects it and refuses to decrypt.

Key Features • Hide secret text, passwords, and multiple file attachments inside a single image • Built-in Voice Recorder & Audio Player to attach encrypted voice notes • Military-grade AES-256 encryption with HMAC-SHA256 tamper protection • Smart .zip sharing so messenger apps like WhatsApp never compress or corrupt your hidden pixels • Use any photo from your camera or photo library, or generate a fresh canvas • Built-in Web Decryptor tester for cross-platform verification • 100% offline & local processing: no accounts, no cloud servers, no tracking

Who is it for? For anyone who wants to share sensitive information privately with a specific person: passwords, confidential documents, private voice memos, or personal messages meant for one recipient only.

Download StegoVault and keep your private information truly private.
