Function, host or master key of Azure Functions, sent as the code query parameter or the x-functions-key header to call an HTTP-triggered function. Keys in the identifiable format are 56 Base64url characters ending in == with the signature AzFu at positions 45 to 48. Older keys and URL-encoded keys are not covered.
