Binary releases

Download and unpack from

Compile from source

git clone
cd trufflehog; go install

Using installation script

curl -sSfL | sh -s -- -b /usr/local/bin

Using installation script, verify checksum signature (requires cosign to be installed)

curl -sSfL | sh -s -- -v -b /usr/local/bin

Using installation script to install a specific version

curl -sSfL | sh -s -- -b /usr/local/bin <ReleaseTag like v3.56.0>

:closed_lock_with_key: Verifying the artifacts

Checksums are applied to all artifacts, and the resulting checksum file is signed using cosign.

You need the following tool to verify signature:

Verification steps are as follow:

  1. Download the artifact files you want, and the following files from the releases page.

    • trufflehog_{version}_checksums.txt
    • trufflehog_{version}_checksums.txt.pem
    • trufflehog_{version}_checksums.txt.sig
  2. Verify the signature:

    cosign verify-blob <path to trufflehog_{version}_checksums.txt> \
    --certificate <path to trufflehog_{version}_checksums.txt.pem> \
    --signature <path to trufflehog_{version}_checksums.txt.sig> \
    --certificate-identity-regexp 'https://github\.com/trufflesecurity/trufflehog/\.github/workflows/.+' \
    --certificate-oidc-issuer ""
  3. Once the signature is confirmed as valid, you can proceed to validate that the SHA256 sums align with the downloaded artifact:

    sha256sum --ignore-missing -c trufflehog_{version}_checksums.txt

Replace {version} with the downloaded files version

Alternatively, if you are using installation script, pass -v option to perform signature verification. This required Cosign binary to be installed prior to running installation script.

:rocket: Quick Start

1: Scan a repo for only verified secrets


trufflehog git --only-verified

Expected output:

🐷🔑🐷  TruffleHog. Unearth your secrets. 🐷🔑🐷

Found verified result 🐷🔑
Detector Type: AWS

Commit: fbc14303ffbf8fb1c2c1914e8dda7d0121633aca
File: keys
Email: counter <counter@counters-MacBook-Air.local>
Timestamp: 2022-06-16 10:17:40 -0700 PDT

2: Scan a GitHub Org for only verified secrets

trufflehog github --org=trufflesecurity --only-verified

3: Scan a GitHub Repo for only verified keys and get JSON output


trufflehog git --only-verified --json

Expected output:

{"SourceMetadata":{"Data":{"Git":{"commit":"fbc14303ffbf8fb1c2c1914e8dda7d0121633aca","file":"keys","email":"counter \u003ccounter@counters-MacBook-Air.local\u003e","repository":"","timestamp":"2022-06-16 10:17:40 -0700 PDT","line":4}}},"SourceID":0,"SourceType":16,"SourceName":"trufflehog - git","DetectorType":2,"DetectorName":"AWS","DecoderName":"PLAIN","Verified":true,"Raw":"AKIAYVP4CIPPERUVIFXG","Redacted":"AKIAYVP4CIPPERUVIFXG","ExtraData":{"account":"595918472158","arn":"arn:aws:iam::595918472158:user/","user_id":"AIDAYVP4CIPPJ5M54LRCY"},"StructuredData":null}

4: Scan a GitHub Repo + its Issues and Pull Requests

trufflehog github --repo= --issue-comments --pr-comments

5: Scan an S3 bucket for verified keys

trufflehog s3 --bucket=<bucket name> --only-verified

6: Scan S3 buckets using IAM Roles

trufflehog s3 --role-arn=<iam role arn>

7: Scan a Github Repo using SSH authentication in docker

docker run --rm -v "$HOME/.ssh:/root/.ssh:ro" trufflesecurity/trufflehog:latest git ssh://

8: Scan individual files or directories

trufflehog filesystem path/to/file1.txt path/to/file2.txt path/to/dir

9: Scan GCS buckets for verified secrets

trufflehog gcs --project-id=<project-ID> --cloud-environment --only-verified

10: Scan a Docker image for verified secrets

Use the --image flag multiple times to scan multiple images.

trufflehog docker --image trufflesecurity/secrets --only-verified

11: Scan in CI

Set the --since-commit flag to your default branch that people merge into (ex: "main"). Set the --branch flag to your PR's branch name (ex: "feature-1"). Depending on the CI/CD platform you use, this value can be pulled in dynamically (ex: CIRCLE_BRANCH in Circle CI and TRAVIS_PULL_REQUEST_BRANCH in Travis CI). If the repo is cloned and the target branch is already checked out during the CI/CD workflow, then --branch HEAD should be sufficient. The --fail flag will return an 183 error code if valid credentials are found.

trufflehog git file://. --since-commit main --branch feature-1 --only-verified --fail

12: Scan a Postman workspace

Use the --workspace, --collection, --environment flags multiple times to scan multiple targets.

trufflehog postman --token=<postman api token> --workspace=<workspace id>

:question: FAQ

  • All I see is 🐷🔑🐷 TruffleHog. Unearth your secrets. 🐷🔑🐷 and the program exits, what gives?
    • That means no secrets were detected
  • Why is the scan taking a long time when I scan a GitHub org
    • Unauthenticated GitHub scans have rate limits. To improve your rate limits, include the --token flag with a personal access token
  • It says a private key was verified, what does that mean?
    • Check out our Driftwood blog post to learn how to do this, in short we've confirmed the key can be used live for SSH or SSL Blog post
  • Is there an easy way to ignore specific secrets?
    • If the scanned source supports line numbers, then you can add a trufflehog:ignore comment on the line containing the secret to ignore that secrets.

:newspaper: 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, Docker, filesystems, S3, GCS, Circle CI and Travis CI.
  • Instantly verify private keys against millions of github users and billions of TLS certificates using our Driftwood technology.
  • Scan binaries, documents, and other file formats
  • Available as a GitHub Action and a pre-commit hook

What is credential verification?

For every potential credential that is detected, we've painstakingly implemented programmatic 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.

:memo: Usage

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

  • git
  • github
  • gitlab
  • docker
  • S3
  • filesystem (files and directories)
  • syslog
  • circleci
  • travisci
  • GCS (Google Cloud Storage)

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

  <uri>  Git repository URL. https://, file://, or ssh:// schema expected.

For example, to scan a git repository, start with

trufflehog git


The S3 source supports assuming IAM roles for scanning in addition to IAM users. This makes it easier for users to scan multiple AWS accounts without needing to rely on hardcoded credentials for each account.

The IAM identity that TruffleHog uses initially will need to have AssumeRole privileges as a principal in the trust policy of each IAM role to assume.

To scan a specific bucket using locally set credentials or instance metadata if on an EC2 instance:

trufflehog s3 --bucket=<bucket-name>

To scan a specific bucket using an assumed role:

trufflehog s3 --bucket=<bucket-name> --role-arn=<iam-role-arn>

Multiple roles can be passed as separate arguments. The following command will attempt to scan every bucket each role has permissions to list in the S3 API:

trufflehog s3 --role-arn=<iam-role-arn-1> --role-arn=<iam-role-arn-2>

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.

:octocat: TruffleHog Github Action

General Usage

      - main

    runs-on: ubuntu-latest
    - name: Checkout code
      uses: actions/checkout@v4
        fetch-depth: 0
    - name: Secret Scanning
      uses: trufflesecurity/trufflehog@main
        extra_args: --only-verified

In the example config above, we're scanning for live secrets in all PRs and Pushes to main. Only code changes in the referenced commits are scanned. If you'd like to scan an entire branch, please see the "Advanced Usage" section below.

Shallow Cloning

If you're incorporating TruffleHog into a standalone workflow and aren't running any other CI/CD tooling alongside TruffleHog, then we recommend using Shallow Cloning to speed up your workflow. Here's an example for how to do it:

      - shell: bash
        run: |
          if [ "${{ github.event_name }}" == "push" ]; then
            echo "depth=$(($(jq length <<< '${{ toJson(github.event.commits) }}') + 2))" >> $GITHUB_ENV
            echo "branch=${{ github.ref_name }}" >> $GITHUB_ENV
          if [ "${{ github.event_name }}" == "pull_request" ]; then
            echo "depth=$((${{ github.event.pull_request.commits }}+2))" >> $GITHUB_ENV
            echo "branch=${{ github.event.pull_request.head.ref }}" >> $GITHUB_ENV
      - uses: actions/checkout@v3
          ref: ${{env.branch}}
          fetch-depth: ${{env.depth}}
      - uses: trufflesecurity/trufflehog@main
          extra_args: --only-verified

Depending on the event type (push or PR), we calculate the number of commits present. Then we add 2, so that we can reference a base commit before our code changes. We pass that integer value to the fetch-depth flag in the checkout action in addition to the relevant branch. Now our checkout process should be much shorter.

Canary detection

TruffleHog statically detects and lets you know when they're present without setting them off. You can learn more here:


Advanced Usage

- name: TruffleHog
  uses: trufflesecurity/trufflehog@main
    # Repository path
    # Start scanning from here (usually main branch).
    # Scan commits until here (usually dev branch).
    head: # optional
    # Extra args to be passed to the trufflehog cli.
    extra_args: --debug --only-verified

If you'd like to specify specific base and head refs, you can use the base argument (--since-commit flag in TruffleHog CLI) and the head argument (--branch flag in the TruffleHog CLI). We only recommend using these arguments for very specific use cases, where the default behavior does not work.

Advanced Usage: Scan entire branch

- name: scan-push
        uses: trufflesecurity/trufflehog@main
          base: ""
          head: ${{ github.ref_name }}
          extra_args: --only-verified

TruffleHog GitLab CI

Example Usage

  - security
  stage: security
  allow_failure: false
  image: alpine:latest
    SCAN_PATH: "." # Set the relative path in the repo to scan
    - apk add --no-cache git curl jq
    - curl -sSfL | sh -s -- -b /usr/local/bin
    - trufflehog filesystem "$SCAN_PATH" --only-verified --fail --json | jq
    - if: '$CI_PIPELINE_SOURCE == "merge_request_event"'

In the example pipeline above, we're scanning for live secrets in all repository directories and files. This job runs only when the pipeline source is a merge request event, meaning it's triggered when a new merge request is created.

Pre-commit Hook

TruffleHog can be used in a pre-commit hook to prevent credentials from leaking before they ever leave your computer.

Key Usage Note:

  • For optimal hook efficacy, execute git add followed by git commit separately. This ensures TruffleHog analyzes all intended changes.
  • Avoid using git commit -am, as it might bypass pre-commit hook execution for unstaged modifications.

An example .pre-commit-config.yaml is provided (see for installation).

  - repo: local
      - id: trufflehog
        name: TruffleHog
        description: Detect secrets in your data.
        entry: bash -c 'trufflehog git file://. --since-commit HEAD --only-verified --fail'
        # For running trufflehog in docker, use the following entry instead:
        # entry: bash -c 'docker run --rm -v "$(pwd):/workdir" -i --rm trufflesecurity/trufflehog:latest git file:///workdir --since-commit HEAD --only-verified --fail'
        language: system
        stages: ["commit", "push"]

Regex Detector (alpha)

TruffleHog supports detection and verification of custom regular expressions. For detection, at least one regular expression and keyword is required. A keyword is a fixed literal string identifier that appears in or around the regex to be detected. To allow maximum flexibility for verification, a webhook is used containing the regular expression matches.

TruffleHog will send a JSON POST request containing the regex matches to a configured webhook endpoint. If the endpoint responds with a 200 OK response status code, the secret is considered verified.

NB: This feature is alpha and subject to change.

Regex Detector Example

# config.yaml
  - name: HogTokenDetector
      - hog
      hogID: '\b(HOG[0-9A-Z]{17})\b'
      hogToken: '[^A-Za-z0-9+\/]{0,1}([A-Za-z0-9+\/]{40})[^A-Za-z0-9+\/]{0,1}'
      - endpoint: http://localhost:8000/
        # unsafe must be set if the endpoint is HTTP
        unsafe: true
          - "Authorization: super secret authorization header"
$ trufflehog filesystem /tmp --config config.yaml --only-verified
🐷🔑🐷  TruffleHog. Unearth your secrets. 🐷🔑🐷

Found verified result 🐷🔑
Detector Type: CustomRegex
Decoder Type: PLAIN
File: /tmp/hog-facts.txt

Data structure sent to the custom verification server:

    "HogTokenDetector": {
        "HogSecret": ["sD9vzqdSsAOxntjAJ/qZ9sw+8PvEYg0r7D1Hhh0C"],

Verification Server Example (Python)

Unless you run a verification server, secrets found by the custom regex detector will be unverified. Here is an example Python implementation of a verification server for the above config.yaml file.

import json
from http.server import BaseHTTPRequestHandler, HTTPServer

AUTH_HEADER = 'super secret authorization header'

class Verifier(BaseHTTPRequestHandler):
    def do_GET(self):

    def do_POST(self):
            if self.headers['Authorization'] != AUTH_HEADER:

            # read the body
            length = int(self.headers['Content-Length'])
            request = json.loads(
            self.log_message("%s", request)

            # check the match, you'll need to implement validateToken, which takes an array of ID's and Secrets
            if not validateTokens(request['HogTokenDetector']['hogID'], request['HogTokenDetector']['hogSecret']): 
                # any other response besides 200
        except Exception:

with HTTPServer(('', 8000), Verifier) as server:
    except KeyboardInterrupt:
