About Reiven.io
Reiven.io is a browser-first project for sending encrypted files and private notes without creating an account. It is built for temporary handovers rather than a permanent online archive.
A small tool for a specific job
Sometimes you need to send one document, hand over a private instruction, or move a file to another device. Reiven lets you encrypt that content locally, upload the encrypted bytes, and share a link or access code.
The server uses process memory for the encrypted upload and its live metadata. A share can expire, be deleted, or disappear when the server restarts. Keep an original copy until the handover is complete.
The Reiven.io project
The project is maintained in the reivenio/reiven-io repository on GitHub. The repository contains the browser application, direct server, encryption configuration, and command-line client, along with installation and deployment instructions.
For bugs, feature suggestions, and general questions, use the project's issue tracker. It is public: include a minimal example and omit actual secrets and private links.
Choose the right sharing flow
- Encrypted files for an existing document or other file.
- Private notes for text you want to write directly in the browser.
- The CLI for terminal-based uploads and downloads.
