GitLeaks

Check git repos for secrets and keys

Features

Search all commits on all branches in topological order
Regex/Entropy checks

Installing

go get -u github.com/zricethezav/gitleaks

Usage and Explanation

./gitleaks {git url}

This example will clone the target {git url} and run a diff on all commits. A report will be outputted to {repo_name}_leaks.json Gitleaks scans all lines of all commits and checks if there are any regular expression matches. The regexs are defined in main.go. Work largely based on https://people.eecs.berkeley.edu/~rohanpadhye/files/key_leaks-msr15.pdf and regexes from https://github.com/dxa4481/truffleHog and https://github.com/anshumanbh/git-all-secrets.

./gitleaks -o {org git url}

Help

usage: gitleaks [options] <git url>

Options:
	-c 			Concurrency factor (default is 10)
	-u --user 		Git user url
	-r --repo 		Git repo url
	-o --org 		Git organization url
	-s --strict 		Strict mode uses stopwords in config.yml
	-b --b64Entropy 	Base64 entropy cutoff (default is 70)
	-x --hexEntropy  	Hex entropy cutoff (default is 40)
	-e --entropy	        Enable entropy
	-h --help 		Display this message

NOTE: your mileage may vary so if you aren't getting the results you expected try updating the regexes to fit your needs or try tweaking the entropy cutoffs and stopwords. Entropy cutoff for base64 alphabets seemed to give good results around 70 and hex alphabets seemed to give good results around 40. Entropy is calculated using Shannon entropy.

If you find a valid leak in a repo

Please read the Github article on removing sensitive data from a repository to remove the sensitive information from your history.
