Everything in Ryzova E-Pen

Start with Send or Receive. More tools are here when you need them.

Direct Send & Receive

1-to-1 encrypted file and folder transfer with selective receive, reconnect recovery, and SHA-256 integrity checks.

Nearby / Same Wi-Fi

Keep file-data ICE local on the same LAN with STUN/TURN disabled. Public rendezvous signaling still requires internet.

Encrypted Clipboard

Move text, links, passwords, phone numbers, and code snippets between connected browsers.

Drop Rooms · PRO host

PRO hosts collect files from several people. Guests send files Free.

Multi-Receiver Broadcast · PRO host

PRO hosts share one file set with multiple receivers. Joining stays Free.

My Devices

Pair trusted browsers locally for encrypted quick handoff while the target browser is online.

Why use Ryzova E-Pen?

Client-side E2EE

AES-GCM 256 with PBKDF2 key derivation. Your password never leaves your browser.

No cloud file storage

Files use WebRTC and are not uploaded to cloud storage. Encrypted traffic may use a TURN relay when a direct connection is unavailable.

Folders & large files

Up to 100,000 files per transfer in the current v2.3 safety envelope, with no fixed E-Pen application-level file-size cap. Practical limits still depend on your browser, device, storage, and network.

v2.3 verified limits

Built for everyday files, large folders, and game-sized transfers

See technical limits & test scope →

The current receiver safety limit is 100,000 files per transfer with a 32 MiB encrypted manifest cap. E-Pen does not set a fixed application-level per-file or total-transfer size cap; actual maximums depend on browser, device, storage, and network conditions.

How E-Pen works

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 between the browsers.
