TruffleHog is the most powerful secrets Discovery, Classification, Validation, and Analysis tool. In this context secret refers to a credential a machine uses to authenticate itself to another machine. This includes API keys, database passwords, private encryption keys, and more...
TruffleHog can look for secrets in many places including Git, chats, wikis, logs, API testing platforms, object stores, filesystems and more
TruffleHog classifies over 800 secret types, mapping them back to the specific identity they belong to. Is it an AWS secret? Stripe secret? Cloudflare secret? Postgres password? SSL Private key? Sometimes its hard to tell looking at it, so TruffleHog classifies everything it finds.
For every secret TruffleHog can classify, it can also log in to confirm if that secret is live or not. This step is critical to know if there’s an active present danger or not.
For the 20 some of the most commonly leaked out credential types, instead of sending one request to check if the secret can log in, TruffleHog can send many requests to learn everything there is to know about the secret. Who created it? What resources can it access? What permissions does it have on those resources?

You need the following tool to verify signature:
Verification steps are as follow:
-
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
-
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"
-
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.

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

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
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.
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)
- postman
- jenkins
- elasticsearch
Each subcommand can have options that you can see with the --help flag provided to the sub command:
$ trufflehog git --help
usage: TruffleHog git [<flags>] <uri>
Find credentials in git repositories.
Flags:
-h, --help Show context-sensitive help (also try --help-long and --help-man).
--log-level=0 Logging verbosity on a scale of 0 (info) to 5 (trace). Can be disabled with "-1".
--profile Enables profiling and sets a pprof and fgprof server on :18066.
-j, --json Output in JSON format.
--json-legacy Use the pre-v3.0 JSON format. Only works with git, gitlab, and github sources.
--github-actions Output in GitHub Actions format.
--concurrency=20 Number of concurrent workers.
--no-verification Don't verify the results.
--results=RESULTS Specifies which type(s) of results to output: verified, unknown, unverified, filtered_unverified. Defaults to all types.
--allow-verification-overlap
Allow verification of similar credentials across detectors
--filter-unverified Only output first unverified result per chunk per detector if there are more than one results.
--filter-entropy=FILTER-ENTROPY
Filter unverified results with Shannon entropy. Start with 3.0.
--config=CONFIG Path to configuration file.
--print-avg-detector-time
Print the average time spent on each detector.
--no-update Don't check for updates.
--fail Exit with code 183 if results are found.
--verifier=VERIFIER ... Set custom verification endpoints.
--custom-verifiers-only Only use custom verification endpoints.
--archive-max-size=ARCHIVE-MAX-SIZE
Maximum size of archive to scan. (Byte units eg. 512B, 2KB, 4MB)
--archive-max-depth=ARCHIVE-MAX-DEPTH
Maximum depth of archive to scan.
--archive-timeout=ARCHIVE-TIMEOUT
Maximum time to spend extracting an archive.
--include-detectors="all" Comma separated list of detector types to include. Protobuf name or IDs may be used, as well as ranges.
--exclude-detectors=EXCLUDE-DETECTORS
Comma separated list of detector types to exclude. Protobuf name or IDs may be used, as well as ranges. IDs defined here take precedence over the include list.
--version Show application version.
-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.
--exclude-globs=EXCLUDE-GLOBS
Comma separated list of globs to exclude in scan. This option filters at the `git log` level, resulting in faster scans.
--since-commit=SINCE-COMMIT
Commit to start scan from.
--branch=BRANCH Branch to scan.
--max-depth=MAX-DEPTH Maximum depth of commits to scan.
--bare Scan bare repository (e.g. useful while using in pre-receive hooks)
Args:
<uri> Git repository URL. https://, file://, or ssh:// schema expected.
For example, to scan a git repository, start with
trufflehog git https://github.com/trufflesecurity/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
--failflag is used.

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.
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 }}" >> $GITHUB_ENV
fi
if [ "${{ 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
fi
- uses: actions/checkout@v3
with:
ref: ${{env.branch}}
fetch-depth: ${{env.depth}}
- uses: trufflesecurity/trufflehog@main
with:
extra_args: --results=verified,unknown
...
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.
TruffleHog statically detects https://canarytokens.org/ and lets you know when they're present without setting them off. You can learn more here: https://trufflesecurity.com/canaries

extra_args: --log-level=2 --results=verified,unknownIf 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).

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 addfollowed bygit commitseparately. 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 pre-commit.com for installation).

stages: ["commit", "push"]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.
