Vial is a small Rust project for end-to-end encrypted secret sharing.

Secrets are encrypted on the client, sent to a server as ciphertext, and decrypted only by the recipient. The server never knows the decryption key or the contents of a secret.

The primary tool is a CLI. A web UI is provided as an optional way to view secrets.

What It Does

• Create encrypted secrets (text or files) using a password or a random key
• Upload encrypted payloads to a server
• Fetch and decrypt secrets locally
• Enforce expiration and view limits on the server
• Self-hostable server or reusable server library

Workspace Members

Installation

1. Run from Source Code:

• Clone the repository git clone https://github.com/TheRustyPickle/Vial
• To run the CLI with Cargo cargo run --release --bin vial
• To run the server with Cargo cargo run --release --bin vial-server

2. Run the latest Release:

• Download the latest executable from Releases.
• Unzip the executable and run via terminal

3. Install using Cargo:

• To install the CLI cargo install vial-cli and run vial --help
• To install the server cargo install vial-server. See here to find the env variable list for the server

Web UI

A web UI is available with source code and is used as the default URL in the CLI. The site uses the same srv-lib and can only perform decryption on the client.
