Protect your sensitive files, photos, secret messages, and passwords with AES Vault—a comprehensive, fully offline cryptographic security suite for Android. Powered by hardware-accelerated 256-bit AES-GCM encryption, memory-hard Argon2id key derivation, and Elliptic Curve X25519 key exchange, AES Vault ensures complete privacy with zero cloud dependencies.

🔐 KEY FEATURES

• AES-256-GCM ENCRYPTION
Authenticated 256-bit symmetric encryption for text, files, photos, videos, PDFs, and archives. Authenticated encryption protects both data confidentiality and integrity with built-in tamper detection.

• FILE & MEDIA ENCRYPTION
Encrypt large files, photos, videos, and documents directly on your local storage with high-speed processing for instant performance and low memory usage.

• IMAGE STEGANOGRAPHY (DATA HIDING IN PHOTOS)
Hide encrypted secret text, documents, or files invisibly inside cover image photos. Advanced steganographic engine ensures hidden data stays completely undetectable while photos look visually identical.

• X25519 ELLIPTIC CURVE KEY EXCHANGE
Establish secure, 256-bit asymmetric key agreements with other users. Safely transmit secret passwords out-of-band without revealing raw key material, verified via 8-character hex fingerprints.

• ENCRYPTED LOCAL VAULT & NOTES
Store secret notes, passwords, and encrypted JSON envelopes locally on your device. Protected by hardware-backed Android KeyStore / TEE encryption with instant biometric autofill.

• MEMORY-HARD ARGON2id & PBKDF2 KDF
Strengthen passwords against GPU and ASIC hardware brute-force attacks using Argon2id (Fast, Balanced, and Maximum security presets) or standard PBKDF2-HMAC-SHA-256 (up to 1,000,000 iterations).

• LIVE QR CODE SCANNER & GENERATOR
Scan encrypted QR code ciphers live using high-speed barcode vision, or export encrypted payloads as QR codes for instant device-to-device sharing.

• ZERO VENDOR LOCK-IN & STANDALONE DECRYPTION
Every exported encrypted payload includes standalone, runnable Python 3, Node.js, and Browser JavaScript decryption scripts. Your data remains fully recoverable on any computer even without this app.

🛡️ PRIVACY & SECURITY GUARANTEES

• Fully Offline: No account registration, no remote servers, no cloud uploads. Plaintext, keys, and files never leave your device.
• Biometric Launch Lock: Require Fingerprint or Face unlock when opening the app.
• Screen Capture Guard: Block screenshots and screen recorders to prevent visual leaks.
• App Integrity Protection: Automatic verification to ensure application security.
