Since 2018, GitGuardian has been scanning for secrets added to GitHub public repositories. When a secret is found, GitGuardian hashes it and stores only a fingerprint of the secret. That fingerprint is what you can search against to verify whether any of your secrets have leaked in public repositories, gists, or issues on GitHub. This service is called Has My Secret Leaked, and in ggshield you’ll see it as the HMSL commands. There’s also a web interface, but in this section we stay in the terminal and use ggshield end to end.
