Nosey Parker

Command-line tool that finds secrets and sensitive information in textual data and Git history.

Key features:
- It supports scanning files, directories, and the entire history of Git repositories
- It uses regular expression matching with a set of 60 patterns chosen for high signal-to-noise based on experience and feedback from offensive security engagements
- It groups matches together that share the same secret, further emphasizing signal over noise
- It is fast: 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
