Binary releases

Download and unpack from https://github.com/trufflesecurity/trufflehog/releases

Compile from source

git clone https://github.com/trufflesecurity/trufflehog.git
cd trufflehog; go install

Using installation script

curl -sSfL https://raw.githubusercontent.com/trufflesecurity/trufflehog/main/scripts/install.sh | sh -s -- -b /usr/local/bin

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

curl -sSfL https://raw.githubusercontent.com/trufflesecurity/trufflehog/main/scripts/install.sh | sh -s -- -v -b /usr/local/bin

Using installation script to install a specific version

curl -sSfL https://raw.githubusercontent.com/trufflesecurity/trufflehog/main/scripts/install.sh | 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:

• Cosign

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 "https://token.actions.githubusercontent.com"

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

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

Command:

trufflehog git https://github.com/trufflesecurity/test_keys --only-verified --json

Expected output:

{"SourceMetadata":{"Data":{"Git":{"commit":"fbc14303ffbf8fb1c2c1914e8dda7d0121633aca","file":"keys","email":"counter \u003ccounter@counters-MacBook-Air.local\u003e","repository":"https://github.com/trufflesecurity/test_keys","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/canarytokens.com@@mirux23ppyky6hx3l6vclmhnj","user_id":"AIDAYVP4CIPPJ5M54LRCY"},"StructuredData":null}
...

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

trufflehog github --repo=https://github.com/trufflesecurity/test_keys --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://github.com/trufflesecurity/test_keys

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-id, --collection-id, --environment flags multiple times to scan multiple targets.

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

13: Scan a Jenkins server

trufflehog jenkins --url https://jenkins.example.com --username admin --password admin

14: Scan an Elasticsearch server

Scan a Local Cluster

There are two ways to authenticate to a local cluster with TruffleHog: (1) username and password, (2) service token.

Connect to a local cluster with username and password

trufflehog elasticsearch --nodes 192.168.14.3 192.168.14.4 --username truffle --password hog

Connect to a local cluster with a service token

trufflehog elasticsearch --nodes 192.168.14.3 192.168.14.4 --service-token ‘AAEWVaWM...Rva2VuaSDZ’

Scan an Elastic Cloud Cluster

To scan a cluster on Elastic Cloud, you’ll need a Cloud ID and API key.

trufflehog elasticsearch \
  --cloud-id 'search-prod:dXMtY2Vx...YjM1ODNlOWFiZGRlNjI0NA==' \
  --api-key 'MlVtVjBZ...ZSYlduYnF1djh3NG5FQQ=='

15. Scan a GitHub Repository for Cross Fork Object References and Deleted Commits

The following command will enumerate deleted and hidden commits on a GitHub repository and then scan them for secrets. This is an alpha release feature.

trufflehog github-experimental --repo https://github.com/<USER>/<REPO>.git --object-discovery

In addition to the normal TruffleHog output, the --object-discovery flag creates two files in a new $HOME/.trufflehog directory: valid_hidden.txt and invalid.txt. These are used to track state during commit enumeration, as well as to provide users with a complete list of all hidden and deleted commits (valid_hidden.txt). If you'd like to automatically remove these files after scanning, please add the flag --delete-cached-data.

Note: Enumerating all valid commits on a repository using this method takes between 20 minutes and a few hours, depending on the size of your repository. We added a progress bar to keep you updated on how long the enumeration will take. The actual secret scanning runs extremely fast.

For more information on Cross Fork Object References, please read our blog post.

: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
