##### Verify checksums file signature

The checksums file provided within the artifacts attached to this
release is signed using
[Cosign](https://docs.sigstore.dev/cosign/overview/) with GitHub
OIDC(Refer [this](https://docs.sigstore.dev/system_config/installation/)
page for cosign installation). To validate the signature of this file,
run the following commands:

```shell

### Download the checksums file, certificate and signature
curl -LO https://github.com/carvel-dev/ytt/releases/download/v0.48.0/checksums.txt
curl -LO https://github.com/carvel-dev/ytt/releases/download/v0.48.0/checksums.txt.pem
curl -LO https://github.com/carvel-dev/ytt/releases/download/v0.48.0/checksums.txt.sig

### Verify the checksums file
cosign verify-blob checksums.txt \
  --certificate checksums.txt.pem \
  --signature checksums.txt.sig \
  --certificate-identity-regexp=https://github.com/carvel-dev \
  --certificate-oidc-issuer=https://token.actions.githubusercontent.com
```

##### Verify binary integrity

### Verify the binary using the checksums file
sha256sum -c checksums.txt --ignore-missing
```
