Uriel

Ephemeral encrypted scratchpad for Windows.

Uriel is a compact tray-first notebook for temporary secrets, logs, commands, and code fragments. It keeps the workflow close at hand, encrypts sensitive content locally, and lets notes disappear on a short lifetime.

Features

• Windows tray flyout with a global Alt + Space shortcut.
• Fixed-size, always-on-top capable borderless window.
• Local AES-256-GCM encryption with Argon2id key derivation in Rust.
• Ephemeral lifetimes: 10 minutes, 1 hour, 24 hours, or burn on copy.
• Clipboard cleanup after 30 seconds.
• RU/EN interface switcher.
• Scrollable note list with a focused editor surface.
• Tray context menu for opening and closing Uriel.
• NSIS installer for Windows x64.

Screenshots

The application uses an obsidian black and silver monochrome interface designed for quick keyboard-first capture from the Windows tray.

Download

Open the Releases page and download the latest Uriel_*_x64-setup.exe installer.

Development

Requirements

• Windows 10 or Windows 11
• Node.js 20+
• Rust stable with the MSVC toolchain
• WebView2 Runtime

Run locally

npm install
npm run tauri dev

The Vite preview is also available with:

npm run dev

Build

npm run build
npm run tauri build

The executable is written to src-tauri/target/release/uriel.exe. The NSIS installer is written to src-tauri/target/release/bundle/nsis/.

Architecture

src/                 React UI and interaction state
src-tauri/src/       Rust commands, crypto, clipboard, tray, and hotkey
src-tauri/capabilities/  Tauri v2 permissions
src-tauri/tauri.conf.json  Windows window and installer configuration

The frontend never needs to access encrypted files directly. Native operations are exposed through narrowly scoped Tauri commands.

Security notes

Uriel is designed for local, short-lived scratch data. AES-GCM provides authenticated encryption and Argon2id derives encryption keys from a password. Clipboard contents are cleared after 30 seconds when possible.

No application can guarantee physical deletion from SSD wear-leveling, filesystem snapshots, backups, or clipboard managers. Treat the ephemeral timer as a cleanup control, not as a forensic deletion guarantee.
