client-side-encryption

End-to-end encrypted notes, tasks, files, passwords, journal and bookmarks. Keyed by a 12-word BIP-39 phrase: no email, no password, no account to leak. The full client source for web, desktop and mobile is published, along with the encryption (XChaCha20-Poly1305, HKDF-SHA256, Ed25519) and the threat model, so the privacy claims are falsifiable.

This tool allows secure file transfers using end-to-end encryption. Neither the content nor the file names are visible to your internet router. It enables easy file sharing between devices (computer, server, phone, etc.) as long as they are connected to the same network, via a locally hosted web interface.

Built for the post-quantum era. Shør is a zero-trust chat platform where keys never leave your device, nothing is logged, and surveillance is cryptographically impossible.

Multi-client bidirectional file synchronization with client-side encryption over any cloud storage, without a dedicated server

hat is a powerful tool designed to provide secure file encryption and decryption directly within your browser. This project, primarily written in JavaScript, ensures that your sensitive data remains private by performing all encryption processes client-side, without the need for server interactions.
