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.
