File vault with password and cryptographic protection.
Steel Vault is a high-grade, zero-knowledge privacy vault engineered to protect your most sensitive photos, 4K videos, documents, audio recordings, and passwords. Built with a strict privacy-first architecture, your private files never touch unencrypted storage, and no one—not even the app developers—can access or recover your data without your master passphrase. Why Choose Steel Vault? Most file vault apps merely hide files behind a shallow lock screen or rename file extensions. Steel Vault fundamentally protects your data at the byte level using authentic authenticated cryptography, hardware-isolated device storage, and automated privacy sanitization. KEY FEATURES & CAPABILITIES: 🔒 AUTHENTIC HIGH-GRADE ENCRYPTION • End-to-end AES-256-GCM & XChaCha20-Poly1305 authenticated encryption. • Argon2id and Scrypt memory-hard key derivation to resist GPU brute-force attacks. • True zero-knowledge architecture: Master encryption keys are derived on-device and never stored on external servers or plain disk. 📸 EXIF GPS & METADATA SANITIZER • Automatic metadata scrubbing upon media import. • Removes GPS coordinates, camera serial numbers, lens profiles, device model markers, and timestamp fingerprints before files are sealed. 🎭 DUAL-PARTITION DECOY VAULT • Plausible deniability system designed for coercive situations. • Configure a secondary Decoy PIN or passphrase that unlocks an alternate, innocent-looking vault workspace while keeping your real vault completely invisible and unindexed. ⚡ ULTRA-FAST STREAMING & 4K VIDEO PLAYBACK • Native support for multi-gigabyte videos, full 4K clips, MOV, MP4, WebM, and MKV formats. • Zero-copy binary stream engine decodes encrypted media directly into hardware playback pipelines without memory bloat or device slowdown. • Batch multi-file import allows swift migration of entire albums and folders. 👁️ BREAK-IN SENTRY & INTRUDER AUDIT • Built-in security monitor logs unauthorized entry attempts. • Captures silent front-camera intruder snapshots with local timestamps after repeated failed passcode entries. • PIN scramble keypad with randomized button layouts stops shoulder-surfing and fingerprint smudge pattern recognition. 👻 STEGO-CLOAK STEGANOGRAPHY STUDIO • Camouflage secret text notes, seed phrases, or private documents directly inside ordinary JPEG and PNG photographs. • Hidden payloads are cryptographically embedded within pixel matrices—completely indistinguishable to standard image viewers. ☁️ AIR-GAPPED & ENCRYPTED CLOUD SYNC • Full offline operation: Works 100% without an internet connection or mandatory account creation. • Export tamper-proof, checksum-verified .svbak encrypted archives for offline backups, cold-storage USB drives, or multi-device restoration. • Optional encrypted cloud backup with version history and device-to-device migration. 📝 PRIVATE MEDIA VIEWER & NOTES • Integrated PDF reader, high-fidelity photo viewer with deep zoom, code syntax viewer, and audio player. • Encrypted scratchpad for passkeys, recovery phrases, API credentials, and confidential records. PERMISSIONS & TRANSPARENCY: • Storage / Media: Strictly required to import and export your selected files. • Camera: Optional, used exclusively for direct in-app secure photo capture and intruder sentry logging. • Biometrics: Optional, used for quick fingerprint or face unlock using device hardware keystore. Take total control over your digital confidentiality. Download Steel Vault today and secure your private life behind uncompromising cryptography.
