About CryptNShare
Post-quantum encrypted file sharing. Upload, protect, share with a scan card.
CryptNShare brings post-quantum secure file sharing to your pocket.
• Upload photos, videos, and documents. Files are encrypted at rest on our servers using hybrid ML-KEM-768 + AES-256-GCM — the same post-quantum scheme used to protect against future quantum computers.
• Create shareable links with password protection, download limits, expiry dates, and email whitelisting.
• Our unique pixelated Sharing Cards let you share files by image — generate a card, send it to a recipient, and they scan it back inside CryptNShare to claim the share. JPEG-robust, rotation-aware, and works even if the image is re-compressed on its way through messaging apps.
• See real-time usage: uploads, downloads, views, storage used.
• Full account control: create and revoke shares, delete files, and sign out on any device.
