# Prerequisites:
# 1. An Azure Key Vault Managed HSM (https://learn.microsoft.com/azure/key-vault/managed-hsm/quick-create-cli)
#
# 2. Three JSON files, containing JWKs, to be used as security domain wrapping keys. Set environment variables
# SD_KEY_1, SD_KEY_2, and SD_KEY_3 to the paths of the files.
#
# 3. azure-keyvault-securitydomain and azure-identity libraries (pip install these)
#
# 4. Set environment variable VAULT_URL with the URL of your managed HSM
#
# 5. 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
