Docker support

Build the image:

docker build -t sdto .

Run the container:

docker run -it --rm sdto -t www.domain.com -v

Using custom fingerprints

You can specify custom fingerprints file via -f path/to/file.json parameter. The expected json file format:

{
  "AWS/S3": {"pattern": "The specified bucket does not exist"},
  "BitBucket": {"pattern": "Repository not found"},
  "Fastly": {"pattern": "Fastly pattern\\: unknown domain\\:", "process_200": true}
}

Note that pattern value is expected to be a python regexp.

Usage as a python library

Example:

import re

from aiohttp import ClientSession
from sdto import check_target, RegexFingerprint


async def main():
    async with ClientSession() as cs:
        fingerprint = await check_target(
            cs=cs,
            target="sub.domain.com",
            ssl=True,
            proxy=None,
            fingerprints=[
                RegexFingerprint(
                    "Github", 
                    re.compile(r"There isn\'t a Github Pages site here\."),
                    process_200=False,
                )
            ]
        )
        if not fingerprint:
            print("No match")
        else:
            print(fingerprint.name)
