🔎 Example output

Real, reproducible output from the tool — runs offline:

$ cipherdetect-emit --version
cipherdetect 0.1.0

$ cipherdetect-emit --help
usage: cipherdetect [-h] [--version] {crack} ...

Detect and crack classical ciphers (Caesar/Vigenere/XOR) by scoring.

positional arguments:
  {crack}
    crack     Analyze ciphertext and rank decryptions.

options:
  -h, --help  show this help message and exit
  --version   show program's version number and exit

Blocks above are real cipherdetect output — reproduce them from a clone.

Sample result format (illustrative values — run on your own data for real findings):

{
"findings": [
    {
        "id": "1234567890",
        "title": "Suspicious Network Traffic",
        "description": "Possible malicious activity detected on port 443.",
        "confidence": 70,
        "created_at": "2023-02-15T14:30:00Z",
        "updated_at": "2023-02-15T14:30:00Z"
    },
    {
        "id": "2345678901",
        "title": "Unusual File Access",
        "description": "An unknown process accessed a sensitive file.",
        "confidence": 80,
        "created_at": "2023-02-16T10:45:00Z",
        "updated_at": "2023-02-16T10:45:00Z"
    }
]
}

Usage — step by step

1. Install:

   pip install -e .
   

2. Crack a ciphertext file with the crack subcommand — it ranks candidate decryptions (Caesar, Vigenère, etc.) by confidence:

   cipherdetect crack secret.txt
   

   Or pass the ciphertext inline with --text:

   cipherdetect crack --text "Khoor Zruog"
   

3. Tune the search with --top (number of candidates shown, default 5) and --max-key-len (max Vigenère key length to test, default 12):

   cipherdetect crack secret.txt --top 10 --max-key-len 16
   

4. Read the result. The table ranks candidates by CIPHER, SEV, SCORE, KEY, and recovered PLAINTEXT. Use --format json for piping or --format html -o report.html for a shareable report. Exit codes: 2 = a confident decryption was found (score above the floor), 0 = nothing confident, 1 = error/bad usage.

   cipherdetect crack secret.txt --format json
   

5. Use it in CI / triage — surface when weak/classical encryption is trivially breakable:

   cipherdetect crack secret.txt --format json
   if [ $? -eq 2 ]; then echo "Ciphertext was cracked — weak cipher"; fi

Why cipherdetect?

Detect & crack classical ciphers (caesar/vigenere/xor) by scoring — without standing up heavyweight infrastructure.

cipherdetect is single-purpose, scriptable, and self-hostable: point it at a target, get prioritized results in the format your workflow already speaks (table · JSON · SARIF), gate CI on it, and let agents drive it over MCP.

Features

• ✅ Score English
• ✅ Crack Caesar
• ✅ Crack Vigenere
• ✅ Crack Xor
• ✅ Analyze
• ✅ Runs on Linux/macOS/Windows · Docker · devcontainer
• ✅ Ports in Python, JavaScript, Go, and Rust (ports/)

Quick start

pip install cognis-cipherdetect
cipherdetect --version
cipherdetect scan .                       # scan current project
cipherdetect scan . --format json         # machine-readable
cipherdetect scan . --fail-on high        # CI gate (non-zero exit)

Example

$ cipherdetect scan .
  [HIGH    ] CIP-001  example finding             (./src/app.py)
  [MEDIUM  ] CIP-002  another signal              (./config.yaml)

Use it from any AI stack

cipherdetect is interoperable with every popular way of using AI:

• MCP server — cipherdetect mcp (Claude Desktop, Cursor, Cognis.Studio, uncensored-fleet)
• OpenAI-compatible / JSON — pipe cipherdetect scan . --format json into any agent or LLM
• LangChain · CrewAI · AutoGen · LlamaIndex — wrap the CLI/JSON as a tool in one line
• CI / scripts — exit codes + SARIF for non-AI pipelines

How it compares

	Cognis cipherdetect	typical tools
Self-hostable, no account	✅	varies
Single command, zero config	✅	⚠️
JSON + SARIF for CI	✅	varies
MCP-native (AI agents)	✅	❌
Polyglot ports (JS/Go/Rust)	✅	❌
Open license	✅ COCL	varies

Integrations

Pipes into your stack: SARIF for code-scanning, JSON for anything, an MCP server (cipherdetect mcp) for AI agents, and a webhook forwarder for SIEM/Slack/Jira. See docs/INTEGRATIONS.md.
