# 1. An Azure Key Vault (https://docs.microsoft.com/en-us/azure/key-vault/quick-create-cli)
#
# 2. azure-keyvault-certificates and azure-identity packages (pip install these)
#
# 3. Set Environment variables AZURE_CLIENT_ID, AZURE_TENANT_ID, AZURE_CLIENT_SECRET, VAULT_URL
# (See https://github.com/Azure/azure-sdk-for-python/tree/master/sdk/keyvault/azure-keyvault-keys#authenticate-the-client)

# ----------------------------------------------------------------------------------------------------------
# Sample - demonstrates basic CRUD operations for certificate issuers.
#
# 1. Create an issuer (create_issuer)
#
# 2. Get an issuer (get_issuer)
#
# 3. List issuers for the key vault (list_properties_of_issuers)
#
# 4. Update an issuer (update_issuer)
#
# 5. Delete an issuer (delete_issuer)
