Phantom Crypt: Vault & Encrypt

Phantom Crypt is your all-in-one, offline encryption toolkit for Android. Protect your text, files, and private notes with industry-standard encryption — no account, no internet required, no data ever leaves your device. WHY PHANTOM CRYPT? Everything happens locally on your phone. We don't have servers that receive your content, and we can't see what you encrypt, hash, or store. Your privacy isn't a promise — it's how the app is built. TEXT & FILE ENCRYPTION Encrypt and decrypt text or entire files using AES-256-GCM, AES-256-CBC, AES-256-CTR, or ChaCha20-Poly1305. Each algorithm shows its strength and popularity at a glance, so you always know what you're choosing. Pro users can batch-encrypt multiple files at once and export results as a ZIP. SECURE VAULT Store encrypted notes in a private vault protected by PIN, password, or biometric unlock. Create multiple vaults for different parts of your life — Work, Personal, and more — each cryptographically isolated from the others. Forgot your PIN? A one-time recovery code generated at setup gets you back in, with zero server involvement. DURESS VAULT (PRO) Set up a second PIN that opens a convincing, empty decoy vault. If you're ever asked to unlock your vault under pressure, the duress PIN protects what matters — indistinguishably from the real thing. HASHING Generate MD5, SHA-1, SHA-256, SHA-512, or CRC32 hashes, with optional HMAC keyed hashing for integrity verification. CLASSICAL CIPHERS Explore Caesar, Vigenère, ROT13, Atbash, Base64, Base32, Hex, Morse code, and Rail Fence cipher — great for learning the fundamentals of cryptography. RSA ENCRYPTION (PRO) Generate 2048-bit RSA keypairs and encrypt or decrypt messages using public-key cryptography. Share your public key freely; only your private key can unlock what's encrypted with it. STEGANOGRAPHY (PRO) Hide encrypted messages inside ordinary-looking images using LSB steganography. Add a password for a second layer of protection — invisible to the eye, locked to anyone without the key. SHARE SECURELY Export encrypted text as a QR code or PDF to share through any app. Pro users can batch-export multiple secrets as a single shareable QR pack. BUILT FOR EVERY DEVICE Phantom Crypt is designed for phones and tablets alike, with full support for landscape mode and gesture or button navigation — no cut-off layouts, no awkward scaling. PRIVACY FIRST - No account or sign-up required - No ads track or sell your data — only standard AdMob advertising identifiers apply - App Lock with PIN, password, or biometric protection - Auto-clearing clipboard option - Full control over what's saved in your activity History, including an option to disable storing decrypted content entirely GO PRO A single one-time purchase (no subscription) unlocks batch file encryption, RSA encryption, steganography, the duress vault, multiple vault profiles, QR batch export, biometric vault unlock, custom accent colors, and removes all ads. Whether you're protecting sensitive notes, sharing a secret securely, or just curious about how encryption works, Phantom Crypt gives you real cryptographic tools in a clean, modern app — entirely under your control.
