ripsecrets is a command-line tool to prevent committing secret keys into your source code. ripsecrets has a few features that distinguish it from other secret scanning tools:

What makes ripsecrets different

ripsecrets has a few features that distinguish it from other secret scanning tools:

  1. Focused on pre-commit. It's a lot cheaper to prevent secrets from getting committed in the first place than dealing with the consequences once a secret that has been committed to your repository has been detected.

  2. Extremely fast. Using a secret scanner shouldn't slow down your development workflow, so ripsecrets is 95 times faster or more than other tools. Learn more about how it's designed for performance.

  3. Always local operation. Many other secret scanners try to verify that the secrets are valid, which is practice means sending strings from your source code to 3rd party services automatically. There's a security versus convenience tradeoff in that decision, but ripsecrets is designed to be the best "local only" tool and will never send data off of your computer.

  4. Low rate of false positives. While local-only tools are always going to have more false positives than one that verifies secrets, ripsecrets uses a probability theory based approach in order to detect keys more accurately than other tools.

  5. Single binary with no dependencies. Installing ripsecrets is as easy as copying the binary into your bin directory.


By default, running ripsecrets will recursively search source files in your current directory for secrets.

$ ripsecrets

For every secret it finds it will print out the file, line number, and the secret that was found. If it finds any secrets it will exit with a non-zero status code.

You can optionally pass a list of files and directories to search as arguments.

$ ripsecrets file1 file2 dir1

This is most commonly used to search files that are about to be committed to source control for accidentally included secrets.

Installing ripsecrets as a pre-commit hook

You can install ripsecrets as a pre-commit hook automatically in your current git repository using the following command:

$ ripsecrets --install-pre-commit

If you would like to install ripsecrets manually, you can add the following command to your pre-commit script:

ripsecrets --strict-ignore `git diff --cached --name-only --diff-filter=ACM`

Passing --strict-ignore ensures that your .secretsignore file is respected when running secrets as a pre-commit.


You can download a prebuilt binary for the latest release from the releases page.

Alternatively, if you have Rust and Cargo installed, you can run:

$ cargo install --git --branch main

Using pre-commit

ripsecrets can work as a plugin for pre-commit with the following configuration.

Note that this may require having Cargo and a Rust compiler already installed. See the pre-commit rust plugin docs for more information.

-   repo:
    # Set your version, be sure to use the latest and update regularly or use 'main'
    rev: v0.1.3
    -   id: ripsecrets

Ignoring secrets

ripsecrets will respect your .gitignore files by default, but there might still be files you want to exclude from being scanned for secrets. To do that you can create a .secretsignore file, which supports similar syntax to a .gitignore file for ignoring files. In addition to excluding files, it also supports a [secrets] section that allows ignoring individual secrets.



In addition to the .secretsignore file, ripsecrets is compatible with detect-secrets style allowlist comments on the same line as the detected secret:

test_secret = "pAznMW3DsrnVJ5TDWwBVCA" # pragma: allowlist secret


The slowest part of secret scanning is looking for potential secrets in a large number of files. To do this quickly ripsecrets does a couple of things:

  1. All the secret patterns are compiled into a single regex, so each file only needs to be processed once.

  2. This regex is fed to ripgrep, which is specially optimized to running a regex against a large number of files quickly.

Additionally, ripsecrets is written in Rust, which means there's no interpreter startup time. To compare real world performance, here's the runtime of a few different scanning tools to search for secrets in the Sentry repo on an M1 air laptop:

tool avg. runtime vs. baseline
ripsecrets 0.32s 1x
trufflehog 31.2s 95x
detect-secrets 73.5s 226x

Most of the time, your pre-commit will be running on a small number of files, so the runtimes above are not typical, but when working with large commits that touch a lot of files the runtime can become noticeable.

Alternative tools

Even if ripsecrets is not the right tool for you, if you're working on a service that deals with user data you should strongly consider using a secret scanner. Here are some alternative tools worth considering:
