About this app

Pocket Cryptographer 24h - is not just another encryption tool, it is a self-destructing cryptographic vault designed for users who demand absolute, time-bound privacy. Built on a "Zero-Trace" philosophy, this app ensures that your most sensitive data remains unreadable by anyone, including yourself, once the daily rotation occurs.

THE 24-HOUR DESTROYER
Every day at 00:00 GMT, the system’s heartbeat resets. A new master key is generated purely in RAM using internal peppers and Argon2id memory-hard derivation. Simultaneously, the app randomly selects one of ten industrial-grade encryption engines. The previous day’s key is purged from existence forever.

101% SECURE BY DESIGN
- Zero Persistence: Keys are never stored on disk, never sent to a server, and never backed up. Once the timer hits zero, the door is locked forever.
- Anti-Surveillance: The app uses system-level protection for preventing digital leakage.
- Ephemeral Clipboard: Encrypted data copied to your clipboard is automatically wiped after 30 seconds to prevent background apps from snooping.
- Perfect Obscurity: Attackers cannot predict which mathematical engine is protecting your data, as the algorithm changes daily.

THE CRYPTOGRAPHIC ARSENAL
We leverage the Bouncy Castle library to provide a rotating rotation of the world’s most trusted ciphers:
- AES-256-GCM (The Industry Standard)
- ChaCha20-Poly1305 & XChaCha20 (High-Performance Modern Crypto)
- Serpent-256-GCM & Twofish-256-GCM (AES Finalists, known for high security margins)
- Threefish-512-CTR (Ultra-wide block encryption)
- Camellia, ARIA, SM4, CAST6 (Global governmental and industrial standards)

THE LAW OF EXPIRATION
Communication is ephemeral. A message encrypted today must be decrypted today. Once the GMT countdown reaches 00:00:00, the message becomes mathematically impossible to recover. This ensures that even if your device is compromised in the future, your past communications remain a black hole.

FEATURES
- Direct Share: Send encrypted payloads directly to messengers like WhatsApp, Telegram, or Signal.
- Intent Integration: Receive text directly from other apps for instant encryption/decryption.
- Visual Progress: Real-time feedback during heavy-duty cryptographic processing.
- Zero Tracking: No analytics, no ads, no internet connection required for core functions.

Protect your words. Respect the timer. Trust the math.
