SecureFile – File Encryption

SecureFile lets you encrypt and decrypt any file directly on your device. Photos, documents, PDFs, videos — if it's a file, SecureFile can lock it behind a password so only you can open it.
HOW IT WORKS
SecureFile uses AES-256-GCM authenticated encryption with PBKDF2-HMAC-SHA256 key derivation. That means your password is never stored — instead it's used to derive a strong encryption key. If someone gets your encrypted file without the password, they get nothing readable.
TWO ENCRYPTION MODES
Simple Mode
Protect a file with just a password. Pick a file, set a password, tap Encrypt. To decrypt later: the encrypted file plus the same password is all you need.
Advanced Mode
Add a second layer with a recovery key. Decryption requires the encrypted file, your password, AND the recovery key file. Even if someone learns your password, they still can't open the file without the key.
COMPLETELY PRIVATE
• No internet connection required — ever
• No account or sign-up needed
• No data sent to any server
• Everything happens on your device, offline
HISTORY
Every encryption and decryption is logged locally in the History tab so you always know which files you've protected and when.
HONEST SECURITY
We don't hide what we use. AES-256-GCM is the same cipher used by banks, governments, and security professionals worldwide. PBKDF2 with 300,000 iterations makes brute-forcing your password computationally impractical. You can verify every detail in the Settings screen.
IMPORTANT NOTE
SecureFile uses standard encryption as defined under U.S. export regulations (EAR). It qualifies for the encryption exemption (ENC) and does not require an Encryption Registration Number (ERN) — it implements only publicly available, standard cryptographic algorithms and is not designed for confidentiality of communications.
If you lose your password (and your recovery key in Advanced Mode), your files cannot be recovered. There is no "forgot password." Store your credentials safely.
