Re: Buildpacks Checksum Site for Release Validation

Any json feed /api ?
Can be nice and more easy to integrate with any CI/CD tool.

I hope cloudfoundry/cli will provide the same thing.

Dear Cloud Foundry Users,

To help operators and users of Cloud Foundry establish a "chain of
custody" for buildpacks, we have launched the following checksum site:

This site provides a checksum for all cached buildpack release zip files
(except for the java-buildpack). Whenever the buildpacks team generates a
new buildpack release, we will immediately compute the SHA256 checksum of
that file and upload it to this website.

The site is hosted on a different repository from the main buildpack
github repositories. It allows operators to validate that the zip file we
produced is the same artifact that has been downloaded and installed.

Additionally, if an operator wishes to further investigate the components
of a buildpack, the "manifest.yml" in each buildpack root directory (for
provides a catalog of every third party component in the buildpack, a URL
of that component's location, and an MD5 checksum of that component.

We hope that this will assist people in auditing the source of their
buildpack code!
