Attestations

Verifying your downloaded files...

You can verify the integrity of all the release assets in any of our projects (whether it's a binary release or a documentation) using the two methods:

  • GitHub Attestations

  • Manual Hashing

Attestations

GitHub have recently introduced a new feature that allows you to verify a binary artifact that a workflow has generated, called the Attestations. To verify your download, once you've downloaded one of the ZIP files, follow these steps:

  1. Install GH CLI 2.49.0 or higher.

  2. Sign in to your GitHub account using gh auth login.

  3. Run this command: gh attestation verify <version>-bin.zip --owner Aptivi, where <version> is a version of Nitrocid that you've downloaded.

If everything is OK, you should see the below message, such as one for Nitrocid KS 0.1.0.10:

Loaded digest sha256:6030eb1eb660f336d8b070202c598e8f51e50c8b9ca9084f30aa8d40ecbb996f for file://0.1.0.10-bin-lite.zip
Loaded 1 attestation from GitHub API
✓ Verification succeeded!

sha256:6030eb1eb660f336d8b070202c598e8f51e50c8b9ca9084f30aa8d40ecbb996f was attested by:
REPO               PREDICATE_TYPE                  WORKFLOW
Aptivi/NitrocidKS  https://slsa.dev/provenance/v1  .github/workflows/prepdraft.yml@refs/tags/v0.1.0.10

If you've seen this error message:

Loaded digest sha256:78fc7b18c2e5e2753934652d294456d11d8dadad6f638dedc31513c4570587a1 for file://0.1.0.10-bin-lite.zip
✗ Loading attestations from GitHub API failed

Error: failed to fetch attestations from Aptivi: HTTP 404: Not Found (https://api.github.com/orgs/Aptivi/attestations/sha256:78fc7b18c2e5e2753934652d294456d11d8dadad6f638dedc31513c4570587a1?per_page=30)

Then, your download is corrupt.

Manual hashing

After you've downloaded the ZIP file, follow these steps:

  1. Open the appropriate release page that matches your version.

  2. Look for a file that you've downloaded from the list of expected hash sums.

  3. Use the sha256sum command against the file if you're running Linux, or use the Get-FileHash -Algorithm sha256 PowerShell command against the file if you're running Windows.

  4. Compare the output.
