Configure Azure Storage Shared Key Authentication

See more REST Examples

Demonstrates Rest.SetAuthAzureStorage, which associates an AuthAzureStorage provider so Chilkat automatically adds a Shared Key Authorization header. The provider supplies the account name, base64 account key, service, and scheme.

Background. Azure Storage Shared Key authorization signs each request with the account access key. The provider also manages the x-ms-version header required by the storage REST API.
