releaser_name      = @Filter/UploadToCPAN       ; The releaser that is being used
upload_to_cpan     = 1             ; Upload the sigstore bundle to CPAN (optional)
sigstore_extension = sigstore.json ; Extension of the sigstore bundle (optional)

DESCRIPTION

This plugin will sign a CPAN Release with SigStore

Required Plugins

This plugin requires that your Dist::Zilla configuration do the following:

1. Create a release

There are numerous combinations of Dist::Zilla plugins that can perform those functions.

SIGSTORE INFORMATION

The current version requires the installation of the cosign application. That application can be accessed via the SigStore web site:

https://docs.sigstore.dev/cosign/system_config/installation/

CPAN SUPPORT

As of version 0.01 there is no support in PAUSE or any CPAN client for sigstore signature verification.

MANUAL SIGNATURE VERIFICATION

cosign verify-blob Dist-Zilla-Plugin-SigStore-SignRelease-0.01.tar.gz \
    --bundle Dist-Zilla-Plugin-SigStore-SignRelease-0.01.tar.gz.sigstore.json \
    --certificate-identity timlegge@gmail.com \
    --certificate-oidc-issuer https://accounts.google.com

The GitHub repository also includes a script in the examples directory that can be used to manually verify signatures.

ATTRIBUTES

• upload_to_cpan true (1) or false (0) - Default = 1

• sigstore_extension Defaults to 'sigstore.json' (Optional) The extension is appended to the end of the distribution's filename.

  example: Distribution-0.99.tar.gz.sigstore.json
  

• answer_yes true (1) or false (0) - Default = 0 This answers yes to any cosign messages that require an answer.

• releaser_name The name of the Dist::Zilla releaser plugin to use for uploading the sigstore bundle. Defaults to '@Filter/UploadToCPAN'. Change this if your bundle plugin has a different name in dist.ini.

  example: releaser_name = @Filter/UploadToCPAN
  

METHODS

• before_release

  The processing function that is called automatically before a release. It attempts to locate the plugin named by releaser_name. If found, it stores the releaser via $self-_releaser> for use during after_release.

• after_release

  The main processing function that is called automatically after the release is complete.

  It signs the release archive with SigStore's cosign and uploads it to PAUSE (if upload_to_cpan = 1)
