# 1. An Azure Key Vault (https://docs.microsoft.com/en-us/azure/key-vault/quick-create-cli)

# Sample - demonstrates basic CRUD operations for the certificate contacts for a key vault.
#
# 1. Create contacts (set_contacts)
#
# 2. Get contacts (get_contacts)
#
# 3. Delete contacts (delete_contacts)

# Notice that the client is using default Azure credentials.
# To make default credentials work, ensure that environment variables 'AZURE_CLIENT_ID',
# 'AZURE_CLIENT_SECRET' and 'AZURE_TENANT_ID' are set with the service principal credentials.
