# Prerequisites:
# 1. An Azure Key Vault (https://learn.microsoft.com/azure/key-vault/quick-create-cli)
#
# 2. azure-keyvault-certificates and azure-identity packages (pip install these)
#
# 3. Set up your environment to use azure-identity's DefaultAzureCredential. For more information about how to configure
# the DefaultAzureCredential, refer to https://aka.ms/azsdk/python/identity/docs#azure.identity.DefaultAzureCredential
#
# ----------------------------------------------------------------------------------------------------------
# Sample - demonstrates the basic CRUD operations on a vault(certificate) resource for Azure Key Vault
#
# 1. Create a new certificate (create_certificate)
#
# 2. Get an existing certificate (get_certificate)
#
# 3. Update an existing certificate (update_certificate)
#
# 4. Delete a certificate (delete_certificate)
#
