AES-256 File Encryption

Encrypt documents, images, and files using industry-standard AES-256 GCM encryption with PBKDF2 key derivation at 480,000 iterations.

🔑
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.

🛡
Secure File Shredding

Permanently and irreversibly delete original files after encryption. No traces left behind.

Biometric Protection

Unlock your encrypted vault using fingerprint or Face ID. 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

01
Select a file

Choose any file from your device — documents, images, PDFs, archives. Any format is supported.

02
Enter a secure password

Create a strong password. This is the only key that will ever unlock your file. It never leaves your device.

03
File encrypted locally

Your file is transformed using AES-256 GCM encryption with PBKDF2 key derivation. All computation happens on-device.

04
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, the file cannot be recovered — by you, by us, or by anyone else. This is not a limitation. This is the guarantee.

Enterprise-Grade
Cryptography

Locked Pages uses the same cryptographic standards trusted by governments, financial institutions, and security researchers worldwide.
