## Overview
### What is Scorecards?
We created Scorecards to give consumers of open-source projects an easy way to
judge whether their dependencies are safe.
Scorecards is an automated tool that assesses a number of important heuristics
[("checks")](#scorecard-checks) associated with software security and assigns
each check a score of 0-10. You can use these scores to understand specific
areas to improve in order to strengthen the security posture of your project.
You can also assess the risks that dependencies introduce, and make informed
decisions about accepting these risks, evaluating alternative solutions, or
working with the maintainers to make improvements.
The inspiration for Scorecards’ logo:
["You passed! All D's ... and an A!"](https://youtu.be/rDMMYT3vkTk)
#### Project Goals
1. Automate analysis and trust decisions on the security posture of open source
projects.
1. Use this data to proactively improve the security posture of the critical
projects the world depends on.
### Prominent Scorecards Users
Scorecards has been run on thousands of projects to monitor and track security
metrics. Prominent projects that use Scorecards include:
- [sos.dev](https://sos.dev)
- [deps.dev](https://deps.dev)
- [metrics.openssf.org](https://metrics.openssf.org)
### Public Data
We run a weekly Scorecards scan of the 1 million most critical open source
projects judged by their direct dependencies and publish the results in a
[BigQuery public dataset](https://cloud.google.com/bigquery/public-data).
This data is available in the public BigQuery dataset
`openssf:scorecardcron.scorecard-v2`. The latest results are available in the
BigQuery view `openssf:scorecardcron.scorecard-v2_latest`.
You can extract the latest results to Google Cloud storage in JSON format using
the [`bq`](https://cloud.google.com/bigquery/docs/bq-command-line-tool) tool:
```
# Get the latest PARTITION_ID
bq query --nouse_legacy_sql 'SELECT partition_id FROM
openssf.scorecardcron.INFORMATION_SCHEMA.PARTITIONS WHERE table_name="scorecard-v2"
AND partition_id!="__NULL__" ORDER BY partition_id DESC
LIMIT 1'
# Extract to GCS
bq extract --destination_format=NEWLINE_DELIMITED_JSON
'openssf:scorecardcron.scorecard-v2$' gs://bucket-name/filename-*.json
```
The list of projects that are checked is available in the
[`cron/data/projects.csv`](https://github.com/ossf/scorecard/blob/main/cron/data/projects.csv)
file in this repository. If you would like us to track more, please feel free to
send a Pull Request with others. Currently, this list is derived from **projects
hosted on GitHub ONLY**. We do plan to expand them in near future to account for
projects hosted on other source control systems.
## Using Scorecards
### Scorecards GitHub Action
The easiest way to use Scorecards on GitHub projects you own is with the
[Scorecards GitHub Action](https://github.com/ossf/scorecard-action). The Action
runs on any repository change and issues alerts that maintainers can view in the
repository’s Security tab. For more information, see the Scorecards GitHub
Action
[installation instructions](https://github.com/ossf/scorecard-action#installation).
### Scorecards Command Line Interface
To run a Scorecards scan on projects you do not own, use the command line
interface installation option.
#### Prerequisites
Platforms: Currently, Scorecards supports OSX and Linux platforms. If you are
using a Windows OS you may experience issues. Contributions towards supporting
Windows are welcome.
Language: You must have GoLang installed to run Scorecards
(https://golang.org/doc/install)
#### Installation
##### Standalone
To install Scorecards as a standalone:
1. Visit our latest
[release page](https://github.com/ossf/scorecard/releases/latest) and
download the correct binary for your operating system
2. Extract the binary file
3. Add the binary to your `GOPATH/bin` directory (use `go env GOPATH` to
identify your directory if necessary)
##### Using Homebrew
You can use [Homebrew](https://brew.sh/) (on macOS or Linux) to install
Scorecards.
```sh
brew install scorecard
```
#### Using Linux package managers
Package Manager | Linux Distribution | Command
---------------------------------------------------------- | ------------------ | -------
Nix | NixOS | `nix-env -iA nixpkgs.scorecard`
[AUR helper](https://wiki.archlinux.org/title/AUR_helpers) | Arch Linux | Use your AUR helper to install `scorecard`
#### Authentication
GitHub imposes [api rate limits](https://developer.github.com/v3/#rate-limiting)
on unauthenticated requests. To avoid these limits, you must authenticate your
requests before running Scorecard. There are two ways to authenticate your
requests: either create a GitHub personal access token, or create a GitHub App
Installation.
- [Create a GitHub personal access token](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token).
When creating the personal access token, we suggest you choose the
`public_repo` scope. Set the token in an environment variable called
`GITHUB_AUTH_TOKEN`, `GITHUB_TOKEN`, `GH_AUTH_TOKEN` or `GH_TOKEN` using the
commands below according to your platform.
```shell
# For posix platforms, e.g. linux, mac:
export GITHUB_AUTH_TOKEN=
# Multiple tokens can be provided separated by comma to be utilized
# in a round robin fashion.
export GITHUB_AUTH_TOKEN=,
# For windows:
set GITHUB_AUTH_TOKEN=
set GITHUB_AUTH_TOKEN=,
```
OR
- [Create a GitHub App Installation](https://docs.github.com/en/developers/apps/building-github-apps/creating-a-github-app)
for higher rate-limit quotas. If you have an installed GitHub App and key
file, you can use the three environment variables below, following the
commands (`set` or `export`) shown above for your platform.
```
GITHUB_APP_KEY_PATH=
GITHUB_APP_INSTALLATION_ID=
GITHUB_APP_ID=
```
These variables can be obtained from the GitHub
[developer settings](https://github.com/settings/apps) page.
#### Basic Usage
##### Docker
`scorecard` is available as a Docker container:
The `GITHUB_AUTH_TOKEN` has to be set to a valid [token](#Authentication)
```shell
docker run -e GITHUB_AUTH_TOKEN=token gcr.io/openssf/scorecard:stable --show-details --repo=https://github.com/ossf/scorecard
```
To use a specific scorecards version (e.g., v3.2.1), run:
```shell
docker run -e GITHUB_AUTH_TOKEN=token gcr.io/openssf/scorecard:v3.2.1 --show-details --repo=https://github.com/ossf/scorecard
```
##### Using repository URL
Scorecards can run using just one argument, the URL of the target repo:
```shell
$ scorecard --repo=github.com/ossf-tests/scorecard-check-branch-protection-e2e

##### Scoring
Each individual check returns a score of 0 to 10, with 10 representing the best
possible score. Scorecards also produces an aggregate score, which is a
weight-based average of the individual checks weighted by risk.
* “Critical” risk checks are weighted at 10
* “High” risk checks are weighted at 7.5
* “Medium” risk checks are weighted at 5
* “Low” risk checks are weighted at 2.5
See the [list of current Scorecards checks](#scorecard-checks) for each check's
risk level.
##### Showing Detailed Results
For more details about why a check fails, use the `--show-details` option:
```
./scorecard --repo=github.com/ossf-tests/scorecard-check-branch-protection-e2e --checks Branch-Protection --show-details

```
##### Using a Package manager
For projects in the `--npm`, `--pypi`, or `--rubygems` ecosystems, you have the
option to run Scorecards using a package manager. Provide the package name to
run the checks on the corresponding GitHub source code.
For example, `--npm=angular`.
##### Running specific checks
To run only specific check(s), add the `--checks` argument with a list of check
names.
For example, `--checks=CI-Tests,Code-Review`.
##### Formatting Results
There are three formats currently: `default`, `json`, and `csv`. Others may be
added in the future.
These may be specified with the `--format` flag. For example, `--format=json`.
#### Report Problems
If you have what looks like a bug, please use the
[Github issue tracking system.](https://github.com/ossf/scorecard/issues) Before
you file an issue, please search existing issues to see if your issue is already
covered.
