Nosey Parker is a command-line program that finds secrets and sensitive information in textual data and Git history.
It is useful both for offensive and defensive security testing.
Nosey Parker is essentially a special-purpose grep-like tool for detection of secrets. The typical workflow is three phases:
- Scan inputs of interest using the scan command.
- Report details of scan results using the report command.
- Review and triage findings.
The scanning and reporting steps are implemented as separate commands because you may wish to generate several reports from one expensive scan run.
This is free and open source software.
Features include:
- Natively scans files, directories, and Git repository history.
- Uses regular expression matching with a set of 151 patterns chosen for high signal-to-noise based on experience and feedback from offensive security engagements.
- Deduplicates its findings, grouping matches together that share the same secret, which in practice can reduce review burden by 100x or more compared to other tools.
- Fast in operation: it can scan at hundreds of megabytes per second on a single core, and is able to scan 100GB of Linux kernel source history in less than 2 minutes on an older MacBook Pro.
- Scalability: it has scanned inputs as large as 20TiB during security engagements.
- Cross-platform support – runs under Linux, macOS, and Windows.
