BETA·Zero-knowledge, peer-to-peer, in your browser
Secure Peer-to-Peer File Sharing
Ryzova E-Pen lets you send files directly between devices with a simple, private peer-to-peer connection.
Zero-knowledge E2EE
AES-GCM 256 with PBKDF2 key derivation. Your password never leaves your browser.
No servers in the path
Files travel browser-to-browser over WebRTC. We only help peers find each other.
Folders & large files
Stream multi-gigabyte folders with chunked transfer — no memory blowups.
01
Pick files
Drop files or folders. We generate a code and password instantly.
02
Share the link
Send the magic link or read the code aloud. Password stays in the URL hash.
03
Transfer
Receiver opens the link — encrypted bytes stream directly between you.
Support Development
E-Pen is free and independently built. During beta, the best way to help is to share feedback and tell others. Sponsorship options arrive after 3.0.
