Gatekeeper CDR (Python)

This package provides native Python bindings to the Gatekeeper CDR core, a zero-trust Content Disarm and Reconstruction engine. It sanitizes potentially malicious files by deeply inspecting and rebuilding them from raw pixel data, effectively stripping away any steganography, macros, or hidden exploits.

Installation

pip install gatekeeper-cdr

(Note: Pre-built wheels are provided for Linux, macOS, and Windows. You do not need Rust installed to use this package).

Usage

import gatekeeper_cdr

# 1. Read a suspicious file
with open("suspicious.jpg", "rb") as f:
    raw_payload = f.read()

# 2. Detect the true format of the file without fully parsing it
try:
    fmt = gatekeeper_cdr.sniff_format(raw_payload)
    print(f"Detected Format: {fmt}") # "Jpeg", "Png", etc.
except Exception as e:
    print(f"Unknown or invalid format: {e}")

# 3. Disarm the file (returns a clean bytes object)
try:
    clean_payload = gatekeeper_cdr.disarm(raw_payload)
    with open("clean.png", "wb") as f:
        f.write(clean_payload)
    print("File successfully sanitized and saved as clean.png!")
except Exception as e:
    print(f"Failed to sanitize file: {e}")

Security

If the file is malformed, structurally invalid, or contains an unknown format, Gatekeeper will intentionally raise an Exception rather than attempting to process it. This default-deny stance ensures that only provably safe files make it into your application's storage.
