Opencrow Stego Toolbox

OpenCROW Stego Toolbox

Use this skill for image or audio artifacts that may hide data in metadata, bit planes, or container structures. It covers steghide for embedded payload extraction and zsteg for PNG/BMP stego triage.

Quick Start

Start the MCP server from the installed CLI:

opencrow-stego-mcp

Verify the mapped stack:

python ~/.codex/skills/opencrow-stego-toolbox/scripts/verify_toolkit.py

Workflow

1. Start with zsteg when the target is a PNG or BMP and you suspect LSB or plane-based data hiding.
2. Start with steghide when the file type matches its embedding model and a passphrase may be involved.
3. Combine this toolbox with opencrow-forensics-toolbox when metadata or carved files may be involved too.
4. If a full profile was installed, use the manual StegSolve or OpenStego steps from the installer summary for GUI-assisted analysis.
5. Prefer the MCP server operations first: toolbox_info, toolbox_verify, toolbox_capabilities, stego_inspect, and stego_extract.
