Audit git repos for secrets

Gitleaks provides a way for you to find unencrypted secrets and other unwanted data types in git source code repositories.

As part of it's core functionality, it provides;

  • Github support including support for bulk organisation and repository owner (user) repository scans, as well as pull request scanning for use in common CI workflows.
  • Support for private repository scans, and repositories that require key based authentication
  • Output in CSV and JSON formats for consumption in other reporting tools and frameworks
  • Externalised configuration for environment specific customisation including regex rules
  • Customisable repository name, file type, commit ID, branchname and regex whitelisting to reduce false positives
  • High performance through the use of src-d's go-git framework

It has been sucessfully used in a number of different scenarios, including;

  • Adhoc scans of local and remote repositories by filesystem path or clone URL
  • Automated scans of github users and organisations (Both public and enterprise platforms)
  • As part of a CICD workflow to identify secrets before they make it deeper into your codebase
  • As part of a wider secrets auditing automation capability for git data in large environments

Example execution

Installation

Written in Go, gitleaks is available in binary form for many popular platforms and OS types from the releases page. Alternatively, executed via Docker or it can be installed using Go directly, as per the below;

Docker
# Run gitleaks against a public repository
docker run --rm --name=gitleaks zricethezav/gitleaks -v -r  https://github.com/zricethezav/gitleaks.git

# Run gitleaks against a local repository already cloned into /tmp/
docker run --rm --name=gitleaks -v /tmp/:/code/  zricethezav/gitleaks -v --repo-path=/code/gitleaks

# Run gitleaks against a specific Github Pull request
docker run --rm --name=gitleaks -e GITHUB_TOKEN={your token} zricethezav/gitleaks --github-pr=https://github.com/owner/repo/pull/9000
Go
go get -u github.com/zricethezav/gitleaks

Usage and Options

gitleaks has a wide range of configuration options that can be adjusted at runtime or via a configuration file based on your specific requirements.

      --gitlab-org=    GitLab group ID to audit
  -c, --commit=        sha of commit to stop at

      --ssh-key=       path to ssh key
      --exclude-forks  exclude forks for organization/user audits
  -e, --entropy=       Include entropy checks during audit. Entropy scale: 0.0(no entropy) - 8.0(max entropy)
  -l, --log=           log level
  -v, --verbose        Show verbose output from gitleaks audit
      --report=        path to write report file
      --redact         redact secrets from log messages and report
      --version        version number
      --sample-config  prints a sample config file

Help Options:
  -h, --help           Show this help message

Exit Codes

Gitleaks provides consistent exist codes to assist in automation workflows such as CICD platforms and bulk scanning.

These can be effectively used in conjunction with the report output file to detect and return meaningful data back to the user or external system about if leaks have been detected, and where they reside.

The code return codes are:

0: no leaks
1: leaks present
2: error encountered
