Azure Provider for the Notation CLI

The notation-azure-kv plugin allows you to sign the Notation-generated payload with a certificate in Azure Key Vault (AKV). The certificate and private key are stored in AKV and the plugin will request signing and obtain the leaf certificate from AKV.

The plugin supports authentication by Azure CLI or Managed Identity. Azure CLI authenticate is used by default. To enable Managed Identity authentication, set the AKV_AUTH_METHOD environment variable to AKV_AUTH_FROM_MI.

Before you begin, make sure the latest version of the Notation CLI has been installed.

1. Navigate to the Releases page and select the latest release of notation-azure-kv. Under the Assets section, select the notation-azure-kv binary for your platform.

2. Validate the checksum using the values in checksums.txt and then install the plugin.

   For Linux Bash:

   version=0.6.0
   
   # validate checksum
   cat checksums.txt | grep notation-azure-kv_${version}_linux_amd64.tar.gz | sha256sum -c
   
   # install the plugin
   mkdir -p "$HOME/.config/notation/plugins/azure-kv"
   tar zxf notation-azure-kv_${version}_linux_amd64.tar.gz -C "$HOME/.config/notation/plugins/azure-kv" notation-azure-kv

   For macOS Zsh:

   version=0.6.0
   
   # validate checksum
   cat checksums.txt | grep notation-azure-kv_${version}_darwin_amd64.tar.gz | shasum -a 256 -c
   
   # install the plugin
   mkdir -p "$HOME/Library/Application Support/notation/plugins/azure-kv"
   tar zxf notation-azure-kv_${version}_darwin_amd64.tar.gz -C "$HOME/Library/Application Support/notation/plugins/azure-kv" notation-azure-kv

   For Windows Powershell:

   $version = "0.6.0"
   
   # validate checksum
   (Get-FileHash .\notation-azure-kv_${version}_windows_amd64.zip).Hash
   
   # install the plugin
   mkdir "$env:AppData\notation\plugins\azure-kv"
   Expand-Archive -Path notation-azure-kv_${version}_windows_amd64.zip -DestinationPath "$env:AppData\notation\plugins\azure-kv"

3. Run notation plugin list and confirm the azure-kv plugin is installed.

1. Sign and verify an artifact with a self-signed Azure Key Vault certificate
2. Sign and verify an artifact with a certificate signed by a trusted CA in Azure Key Vault

Note Please make sure the certificate is in PEM format. PCKS#12 will be supported in the future.
