About Crypted - secure data sharing without any trace
Crypted is a secure platform for sharing sensitive data that is encrypted.
I'm a dev by trade, and I needed a solution to share sensitive data. Existing solutions either: Store your data on their servers (even if "encrypted"); Require downloads/apps that non-tech people won't use; Cost way too much for occasional use; Have terrible UX that makes sharing painful; So I built something different: Crypted - a secure platform for sharing sensitive data that is encrypted client-side using AES-256-GCM before it ever leaves your device. The server literally cannot decrypt your messages even if it wanted to. The technical bits: Uses Web Crypto API for encryption (no sketchy third-party libraries); Two encryption modes: Symmetric (AES-256-GCM): Decryption keys embedded in URL fragments (#key) that never hit the server; also password encrypted method for premium user; Asymmetric (RSA-OAEP): Public/private key pairs for sending data without sharing passwords; Generate your own RSA key pairs in-browser - private keys never leave your device and are encrypted with your password; Send encrypted messages to people using their public keys - no need to share secret links; Messages self-destruct based on time or view count; Supports files up to 100MB (also encrypted); Zero-knowledge architecture - no one can't read your stuff even with server access, not even me; Real use cases I've seen: Lawyers sharing case details with clients; HR sending salary info to employees; Developers sharing API keys, passwords temporarily; Anyone who's tired of putting sensitive stuff in regular email; Already 200 users, 0 expenses, but much more potential.
