Find credentials all over the place (6)

docker run -it -v "$PWD:/pwd" trufflesecurity/trufflehog:latest github --org=trufflesecurity

What's new in v3?

TruffleHog v3 is a complete rewrite in Go with many new powerful features.

  • We've added over 700 credential detectors that support active verification against their respective APIs.
  • We've also added native support for scanning GitHub, GitLab, filesystems, and S3.
  • Instantly verify private keys against millions of github users and billions of TLS certificates using our Driftwood technology.

What is credential verification?

For every potential credential that is detected, we've painstakingly implemented programatic verification against the API that we think it belongs to. Verification eliminates false positives. For example, the AWS credential detector performs a GetCallerIdentity API call against the AWS API to verify if an AWS credential is active.


Several options:

1. Go

git clone trufflehog; go install

2. Release binaries

3. Docker

Note: Apple M1 hardware users should run with docker run --platform linux/arm64 for better performance.

Most users

docker run -it -v "$PWD:/pwd" trufflesecurity/trufflehog:latest github --repo

Apple M1 users

The linux/arm64 image is better to run on the M1 than the amd64 image. Even better is running the native darwin binary avilable, but there is not container image for that.

docker run --platform linux/arm64 -it -v "$PWD:/pwd" trufflesecurity/trufflehog:latest github --repo 

4. Pip (help wanted)

It's possible to distribute binaries in pip wheels.

Here is an example of a project that does it.

Help with setting up this packaging would be appreciated!

5. Brew

brew tap trufflesecurity/trufflehogbrew install trufflehog


TruffleHog has a sub-command for each source of data that you may want to scan:

  • git
  • github
  • gitlab
  • S3
  • filesystem
  • syslog
  • file and stdin (coming soon)

Each subcommand can have options that you can see with the -h flag provided to the sub command:

$ trufflehog git --helpusage: TruffleHog git [<flags>] <uri>Find credentials in git repositories.Flags:      --help                     Show context-sensitive help (also try --help-long and --help-man).      --debug                    Run in debug mode      --version                  Prints trufflehog version.  -j, --json                     Output in JSON format.      --json-legacy              Use the pre-v3.0 JSON format. Only works with git, gitlab, and github sources.      --concurrency=1            Number of concurrent workers.      --no-verification          Don't verify the results.      --only-verified            Only output verified results.      --print-avg-detector-time  Print the    average time spent on each detector.      --no-update                Don't check for updates.  -i, --include-paths=INCLUDE-PATHS                                 Path to file with newline separated regexes for files to include in scan.  -x, --exclude-paths=EXCLUDE-PATHS                                 Path to file with newline separated regexes for files to exclude in scan.      --since-commit=SINCE-COMMIT                                 Commit to start scan from.      --branch=BRANCH            Branch to scan.      --max-depth=MAX-DEPTH      Maximum depth of commits to scan.      --allow                    No-op flag for backwards compat.      --entropy                  No-op flag for backwards compat.      --regex                    No-op flag for backwards compat.Args:  <uri>  Git repository URL. https:// or file:// schema expected.

For example, to scan a git repository, start with

$ trufflehog git

Exit Codes:

  • 0: No errors and no results were found.
  • 1: An error was encountered. Sources may not have completed scans.
  • 183: No errors were encountered, but results were found. Will only be returned if --fail flag is used.

Scanning an organization

Try scanning an entire GitHub organization with the following:

docker run -it -v "$PWD:/pwd" trufflesecurity/trufflehog:latest github --org=trufflesecurity

TruffleHog OSS Github Action

- name: TruffleHog OSS  uses: trufflesecurity/[email protected]  with:    # Repository path    path:     # Start scanning from here (usually main branch).    base:     # Scan commits until here (usually dev branch).    head: # optional

The TruffleHog OSS Github Action can be used to scan a range of commits for leaked credentials. The action will fail if any results are found.

For example, to scan the contents of pull requests you could use the following workflow:

name: Leaked Secrets Scanon: [pull_request]jobs:  TruffleHog:    runs-on: ubuntu-latest    steps:      - name: Checkout code        uses: actions/[email protected]        with:          fetch-depth: 0      - name: TruffleHog OSS        uses: trufflesecurity/[email protected]        with:          path: ./          base: ${{ github.event.repository.default_branch }}          head: HEAD


This project exists thanks to all the people who contribute. [Contribute].


Contributions are very welcome! Please see our contribution guidelines first.

We no longer accept contributions to TruffleHog v2, but that code is available in the v2 branch.

Adding new secret detectors

We have published some documentation and tooling to get started on adding new secret detectors. Let's improve detection together!

License Change

Since v3.0, TruffleHog is released under a AGPL 3 license, included in LICENSE. TruffleHog v3.0 uses none of the previous codebase, but care was taken to preserve backwards compatibility on the command line interface. The work previous to this release is still available licensed under GPL 2.0 in the history of this repository and the previous package releases and tags. A completed CLA is required for us to accept contributions going forward.
