CryptNShare
Post Quantum Encrypted Files
Free · Designed for iPad. Not verified for macOS.
CryptNShare is a secure file-sharing app built for a post-quantum world.
Every file you upload is encrypted at rest using a hybrid scheme that combines post-quantum cryptography (ML-KEM-768) with
AES-256-GCM — protecting your data against both today's threats and future quantum attacks.
KEY FEATURES
• Post-Quantum Encryption — Files are protected with ML-KEM-768, a NIST-standardized post-quantum algorithm, layered with
AES-256-GCM.
• Secure Share Links — Generate shareable links for any file with full control over who can access them.
• Access Controls — Protect shares with passwords, restrict access to specific email addresses, set expiry dates, and limit the
number of downloads.
• Encrypted at Rest — Your files are never stored in plain text. Encryption and decryption happen with streaming chunks for
performance and security.
• Simple, Fast Sharing — Upload from your photo library or files, get a link, and share in seconds.
• Sign In Your Way — Use email, your Google account, or Sign in with Apple.
WHO IT'S FOR
CryptNShare is for anyone who needs to share sensitive documents, photos, or files without compromising privacy — professionals,
teams, and individuals who take security seriously.
Whether you're sending a contract, a personal document, or confidential work files, CryptNShare keeps your data protected from
the moment it leaves your device.
Download CryptNShare and share with confidence.
