Powerful Cryptography.
Simple Interface.
AES-256 File Encryption
Encrypt documents, images, and files using industry-standard AES-256 GCM encryption with Argon2id key derivation, which is memory-hard and first in OWASP's password-storage guidance.
Hybrid RSA Secure Sharing
Share encrypted files securely without sending passwords. Public-key cryptography keeps communication safe end-to-end.
Digital Signatures
Verify file authenticity and ensure your files have not been tampered with or modified in transit.
Overwrite Before Delete
After encryption the original can be overwritten three times with random data and then deleted. Phone flash storage moves data between cells on its own, so no app can promise every old copy is gone; your phone's built-in storage encryption covers what an overwrite cannot reach.
Biometric Protection
Unlock your encrypted vault using fingerprint or face recognition. Fast access without compromising security.
Zero-Knowledge Architecture
We cannot access your files. We cannot recover your password. We cannot see what you protect. That's the point.
How Locked Pages
Protects You
Select a file
Choose any file on your device: documents, images, PDFs or archives. Any format is supported.
Enter a secure password
Create a strong password. This is the only key that will ever unlock your file. It never leaves your device.
File encrypted locally
Your file is transformed using AES-256 GCM encryption with Argon2id key derivation. All computation happens on-device.
Only your password unlocks it
The encrypted file is useless without your password. No backdoor. No master key. No recovery system.
Zero Knowledge means Zero Recovery.
If you forget your password, nobody can recover the file: not you, not us, not anyone. This is not a limitation. This is the design.
Enterprise-Grade
Cryptography
Locked Pages uses the same cryptographic standards trusted by governments, financial institutions, and security researchers worldwide.
