article about custom patterns for secret scanning regular expression syntax for custom patterns defining a custom pattern for a repository defining a custom pattern for an organization defining a custom pattern for an enterprise account editing a custom pattern removing a custom pattern you can extend secret scanning to detect secrets beyond the default patterns secret scanning alerts for partners run automatically on all public repositories if you have a license for github advanced security you can enable and configure secret scanning alerts for users for any repository owned by an organization for more information see about secret scanning alerts for users and about github advanced security about custom patterns for secret scanning you can define custom patterns to identify secrets that are not detected by the default patterns supported by secret scanning for example you might have a secret pattern that is internal to your organization for details of the supported secrets and service providers see secret scanning patterns you can define custom patterns for your enterprise organization or repository secret scanning supports up to 500 custom patterns for each organization or enterprise account and up to 100 custom patterns per repository you can also enable push protection for custom patterns for more information about push protection see protecting pushes with secret scanning regular expression syntax for custom patterns you can specify custom patterns for secret scanning as one or more regular expressions secret format an expression that describes the format of the secret itself before secret an expression that describes the characters that come before the secret by default this is set to a 0 9a za z which means that the secret must be at the start of a line or be preceded by a non alphanumeric character after secret an expression that describes the characters that come after the secret by default this is set to z 0 9a za z which means that the secret must be followed by a new line or a non alphanumeric character additional match requirements one or more optional expressions that the secret itself must or must not match for simple tokens you will usually only need to specify a secret format the other fields provide flexibility so that you can specify more complex secrets without creating complex regular expressions for an example of a custom pattern see example of a custom pattern specified using additional requirements below secret scanning uses the hyperscan library and only supports hyperscan regex constructs which are a subset of pcre syntax hyperscan option modifiers are not supported for more information on hyperscan pattern constructs see pattern support in the hyperscan documentation defining a custom pattern for a repository before defining a custom pattern you must ensure that secret scanning is enabled on your repository for more information see configuring secret scanning for your repositories on github com navigate to the main page of the repository under your repository name click settings in the security section of the sidebar click code security and analysis under code security and analysis find github advanced security under secret scanning under custom patterns click new pattern enter the details for your new custom pattern you must at least provide the name for your pattern and a regular expression for the format of your secret pattern you can click more options to provide other surrounding content or additional match requirements for the secret format provide a sample test string to make sure your configuration is matching the patterns you expect when you re ready to test your new custom pattern to identify matches in the repository without creating alerts click save and dry run when the dry run finishes you ll see a sample of results up to 1000 review the results and identify any false positive results edit the new custom pattern to fix any problems with the results then to test your changes click save and dry run when you re satisfied with your new custom pattern click publish pattern optionally to enable push protection for your custom pattern click enable note push protection for custom patterns will only apply to repositories that have secret scanning as push protection enabled for more information see enabling secret scanning as a push protection for a repository enabling push protection for commonly found custom patterns can be disruptive to contributors after your pattern is created secret scanning scans for any secrets in your entire git history on all branches present in your github repository for more information on viewing secret scanning alerts see managing alerts from secret scanning example of a custom pattern specified using additional requirements a company has an internal token with five characteristics they use the different fields to specify how to identify tokens as follows characteristic field and regular expression length between 5 and 10 characters secret format aa za z0 9 5 10 does not end in a after secret contains numbers and uppercase letters additional requirements secret must match a z and 0 9 does not include more than one lowercase letter in a row additional requirements secret must not match a z 2 contains one of additional requirements secret must match these tokens would match the custom pattern described above a9 aaft secret string match a9 aaft ee95gg za942 aa secret string match za942 a a9 aa ee9 secret string match a9 aa these strings would not match the custom pattern described above a9 aa a aaaaa aa9 aa ee9 aaaae9 defining a custom pattern for an organization before defining a custom pattern you must ensure that you enable secret scanning for the repositories that you want to scan

you want to perform the dry run select selected repositories then search for and select up to 10 repositories when you re ready to test your new custom pattern click run when the dry run finishes you

enabling push protection for commonly found custom patterns can be disruptive to contributors after your pattern is created secret scanning scans for any secrets in repositories in your organization including their entire git history on all branches organization owners and repository administrators will be alerted to any secrets found and can review the alert in the repository where the secret is found for more information on viewing secret scanning alerts see managing alerts from secret scanning defining a custom pattern for an enterprise account before defining a custom pattern you must ensure that you enable secret scanning for your enterprise account for more information see enabling github advanced security for your enterprise notes at the enterprise level only the creator of a custom pattern can edit the pattern and use it in a dry run enterprise owners can only make use of dry runs on repositories that they have access to and enterprise owners do not necessarily have
