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