Introduction

CredSweeper is a tool to detect credentials in any directories or files. CredSweeper could help users to detect unwanted exposure of credentials (such as tokens, passwords, api keys etc.) in advance. By scanning lines, filtering, and using AI model as option, CredSweeper reports lines with possible credentials, where the line is, and expected type of the credential as a result.

Full documentation can be found here: https://credsweeper.readthedocs.io/

How To Use

Config

credsweeper/secret/config.json - Configuration file for pre-processing of CredSweeper. For more details please check here.

You can set the pattern, extension and path you want to exclude from scanning as below.

{
    "exclude": {
        "pattern": [
            "AKIA[0-9A-Z]{9}EXAMPLE",
            ...
        ],
        "extension": [
            "gif",
            "jpg",
            ...
        ],
        "path": [
            "/.git/",
            "/openssl/",
            ...
        ]
    },
    ...
}

And you can also set source_ext, source_quote_ext, find_by_ext_list, check_for_literals, line_data_output, and candidate_output as below.

• source_ext: List of extensions for scanning categorized as source files.
• source_quote_ext: List of extensions for scanning categorized as source files that using quote.
• find_by_ext_list: List of extensions to detect only extensions.
• check_for_literals: Bool value for whether to check line has string literal declaration or not.
• line_data_output: List of attributes of line_data for output.
• candidate_output: List of attributes of candidate for output.

{
    ...
    "source_ext": [
        ".py",
        ".cpp",
        ...
    ],
    "source_quote_ext": [
        ".py",
        ".cpp",
        ...
    ],
    "find_by_ext_list": [
        ".pem",
        ".cer",
        ...
    ],
    "check_for_literals": true,
    "line_data_output": [
        "line",
        "line_num",
        ...
    ],
    "candidate_output": [
        "rule",
        "severity",
        ...
    ]
}

Develop

Tests

To run all tests:

python -m pytest --cov=credsweeper --cov-report=term-missing -s tests/

To run only tests independent of external api:

python -m pytest -m "not api_validation_test" tests/

To obtain manageable (without subprocesses) coverage:

python -m pytest --cov=credsweeper --cov-report=html tests/ --ignore=tests/test_app.py

Benchmark

We have a dataset for testing credential scanners that called CredData. If you want to test CredSweeper with this dataset please check here.

Overall Architecture

Retrain Model

If you want to check how model was trained or retrain it on your own data, please refer to the experiment folder

License
