No accounts, no internet, no cloud — everything happens on your device.\n\n<b>Security</b>\n• AES-256-GCM-SIV (RFC 8452) — nonce-misuse resistant authenticated encryption\n• Argon2id key derivation (256 MiB memory cost) — GPU/ASIC resistant\n• HKDF-SHA512 key expansion with per-version domain separation\n• VAULTX04 format with authenticated header (AAD on every chunk)\n• 100% Safe Rust core — zero unsafe blocks in the crypto library\n• Zero internet permissions, zero storage permissions (uses SAF)\n• Keys and plaintext wiped from RAM with Zeroizing<T> on drop\n\n<b>Features</b>\n• Encrypt any file to a .vx2 container\n• Decrypt .vx2 files back to original\n• Batch processing — queue multiple files with one passphrase\n• Auto-detects encrypt vs decrypt mode from file magic bytes\n• Cancel mid-operation (within one 1 MiB chunk)\n• Password strength meter\n• Secure wipe original file after encryption (with confirmation)\n• Open source (GPLv3)\n\n<b>How it works</b>\n1. Select a file (or drop one from your file manager)\n2. Enter a strong passphrase\n3. Tap ENCRYPT — your file is encrypted to .vx2 beside the original\n4. Optionally wipe the original file\n\nYour passphrase never leaves the device. There is no recovery — if you forget the passphrase, your files are gone. This is by design.\n\n<b>Privacy</b>\n• No analytics, no tracking, no telemetry\n• No network permissions in the APK\n• No storage permissions (uses Android Storage Access Framework)\n• No backup (android:allowBackup=false)\n• Source code available at gitlab.com/theredhacker0345/neuron-encrypt\n\n<b>Technical specs</b>\n• Cipher: AES-256-GCM-SIV with BE32 streaming (1 MiB chunks)\n• KDF: Argon2id (m=256 MiB, t=3, p=4, 64-byte output)\n• RNG: OS CSPRNG (OsRng via getrandom)\n• Min Android: 7.0 (API 24)\n• ABIs: arm64-v8a, armeabi-v7a, x86_64, x86\n","categories":["File Encryption & Vault"]}
