# ----------------------------------------------------------------------------------------------------------
# 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 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)
# ----------------------------------------------------------------------------------------------------------

# Instantiate a certificate client that will be used to call the service.
# Here we use the DefaultAzureCredential, but any azure-identity credential can be used.
VAULT_URL = os.environ["VAULT_URL"]
credential = DefaultAzureCredential()
client = CertificateClient(vault_url=VAULT_URL, credential=credential)

# First we specify the AdministratorContact for our issuers.
admin_contacts = [
    AdministratorContact(first_name="John", last_name="Doe", email="admin@microsoft.com", phone="4255555555")
]

# Next we create an issuer with these administrator details
# The name field refers to the name you would like to get the issuer. There are also pre-set names, such as 'Self' and 'Unknown'
# The provider for your issuer must exist for your vault location and tenant id.
client.create_issuer(
    issuer_name="issuer1", provider="Test", account_id="keyvaultuser", admin_contacts=admin_contacts, enabled=True
)

# Now we get this issuer by name
issuer1 = client.get_issuer(issuer_name="issuer1")
assert issuer1.admin_contacts

print(issuer1.name)
print(issuer1.provider)
print(issuer1.account_id)

for contact in issuer1.admin_contacts:
    print(contact.first_name)
    print(contact.last_name)
    print(contact.email)
    print(contact.phone)

# Now we update the administrator contact for this issuer
admin_contacts = [
    AdministratorContact(first_name="Jane", last_name="Doe", email="admin@microsoft.com", phone="4255555555")
]
issuer1 = client.update_issuer(issuer_name="issuer1", admin_contacts=admin_contacts)
assert issuer1.admin_contacts

for contact in issuer1.admin_contacts:
    print(contact.first_name)
    print(contact.last_name)
    print(contact.email)
    print(contact.phone)

# Now we will list all of the certificate issuers for this key vault. To better demonstrate this, we will first create another issuer.
client.create_issuer(issuer_name="issuer2", provider="Test", account_id="keyvaultuser", enabled=True)

issuers = client.list_properties_of_issuers()

for issuer in issuers:
    print(issuer.name)
    print(issuer.provider)

# Finally, we delete our first issuer by name.
client.delete_issuer("issuer1")

print("\nrun_sample done")
