<summary>Verifying the artifacts</summary>

First, download the [`checksums.txt` file](https://github.com/charmbracelet/gum/releases/download/0.16.2/checksums.txt), for example, with `wget`:

```bash
wget 'https://github.com/charmbracelet/gum/releases/download/v0.16.2/checksums.txt'
```

Then, verify it using [`cosign`](https://github.com/sigstore/cosign):

```bash
cosign verify-blob \
  --certificate-identity 'https://github.com/charmbracelet/meta/.github/workflows/goreleaser.yml@refs/heads/main' \
  --certificate-oidc-issuer 'https://token.actions.githubusercontent.com' \
  --cert 'https://github.com/charmbracelet/gum/releases/download/v0.16.2/checksums.txt.pem' \
  --signature 'https://github.com/charmbracelet/gum/releases/download/v0.16.2/checksums.txt.sig' \
  ./checksums.txt
```

If the output is `Verified OK`, you can safely use it to verify the checksums of other artifacts you downloaded from the release using `sha256sum`:

```bash
sha256sum --ignore-missing -c checksums.txt
```

Done! You artifacts are now verified!
