ShadowGuard

An elite, 100% air-gapped DevSecOps extension that detects leaked API keys, credentials, and custom database passwords in real-time as you type.

Unlike standard regex-based scanners that only look for known vendor prefixes (like AWS or Stripe), ShadowGuard is powered by a locally executing, multi-threaded Go engine that calculates Shannon Entropy. If you type a highly random, custom 32-character password, ShadowGuard's mathematical engine will instantly flag it.

The Architecture

• Zero Latency: The engine is written in Go, utilizing concurrent buffers to scan files in microseconds without blocking the Node.js event loop.
• 100% Air-Gapped: No cloud telemetry. No user accounts. No API keys required. Your code never leaves your local machine.
• Cryptographic Detection: Uses Shannon Entropy algorithms ($H = - \sum p_i \log_2(p_i)$) to detect unknown, custom secrets that bypass standard linters.

Features

• Scans all standard text and code documents locally.
• Highlights vulnerabilities instantly with red diagnostic squiggles.
• Supports Windows, macOS (Intel & Apple Silicon), and Linux via bundled cross-compiled binaries.

Usage

Simply install the extension and write code. ShadowGuard runs silently in the background and will only alert you when a critical entropy threshold is breached.
