Generating a regular expression for a repository using the generator

{% data reusables.repositories.navigate-to-repo %} {% data reusables.repositories.sidebar-settings %} {% data reusables.repositories.navigate-to-code-security-and-analysis %} {% data reusables.repositories.navigate-to-ghas-settings %} {% data reusables.advanced-security.secret-scanning-new-custom-pattern %} {% data reusables.advanced-security.secret-scanning-generate-regular-expression-custom-pattern %}

1. When you're ready to test your new custom pattern, to identify matches in the repository without creating alerts, click Save and dry run. {% data reusables.advanced-security.secret-scanning-dry-run-results %} {% data reusables.advanced-security.secret-scanning-create-custom-pattern %}
