vnsh

The Ephemeral Dropbox for AI - CLI tool for host-blind encrypted sharing.

Features

• Host-blind encryption: AES-256-CBC encryption happens locally
• Server never sees your keys: Keys travel only in the URL fragment
• Ephemeral: Data vaporizes after 24 hours (configurable)
• Simple: Pipe anything, get a shareable URL

Installation

# Zero-install (just run it)
echo "hello" | npx vnsh

# Or install globally
npm install -g vnsh

CLI Usage

Upload content

# Pipe text
echo "hello world" | vn

# Upload a file
vn secret.env

# Pipe from command
git diff | vn
cat crash.log | vn
docker logs app | vn

# Set custom expiry (1-168 hours)
vn -t 1 temp.txt    # Expires in 1 hour

Read content

# Decrypt and display content from a vnsh URL
vn read "https://vnsh.dev/v/abc123#k=...&iv=..."

Options

-t, --ttl <hours>    Set expiry time (default: 24, max: 168)
-p, --price <usd>    Set price for x402 payment
-H, --host <url>     Override API host
-l, --local          Output encrypted blob locally (no upload)
-v, --version        Show version
-h, --help           Show help

Programmatic Usage

import { share, read, readString } from 'vnsh';

// Share content
const url = await share('Hello, World!');
console.log(url);
// https://vnsh.dev/v/abc123#k=...&iv=...

// Share with options
const url2 = await share(buffer, { ttl: 1 }); // 1 hour expiry

// Read content as Buffer
const buffer = await read(url);

// Read content as string
const text = await readString(url);

Environment Variables

• VNSH_HOST - Override the default API host (default: https://vnsh.dev)

Security

• Encryption keys are generated locally and never sent to the server
• Keys travel only in the URL fragment (#k=...), which is never transmitted to servers
• The server stores only encrypted binary blobs
• All data vaporizes after the configured TTL
