Opencrow Stego Toolbox
Use the OpenCROW steganography stack for hidden-data triage and extraction. Use when an agent needs `steghide`, `zsteg`, or when a full install tracks manual StegSolve or OpenStego setup.

Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

OpenCROW Stego Toolbox
Runtime preflight
Probe required commands with command -v and Python modules with importlib.util.find_spec before use. Prefer a PATH-resolved OpenCROW MCP helper or the ctf/sage environment when available, then the managed helper or system Python. If a capability is missing, stop that path safely and report the exact missing command or module.
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-mcpVerify the mapped stack:
python3 scripts/verify_toolkit.pyWorkflow
- Start with
zstegwhen the target is a PNG or BMP and you suspect LSB or plane-based data hiding. - Start with
steghidewhen the file type matches its embedding model and a passphrase may be involved. - Combine this toolbox with
opencrow-forensics-toolboxwhen metadata or carved files may be involved too. - If a full profile was installed, use the manual StegSolve or OpenStego steps from the installer summary for GUI-assisted analysis.
- Prefer the MCP server operations first:
toolbox_info,toolbox_verify,toolbox_capabilities,stego_inspect, andstego_extract.
