Service Encryption is now available for Azure Blob Storage (block and page blobs) upon request for any new storage account created through Azure Resource Manager.
Accounts enabled with this feature encrypt data with Microsoft-managed keys by using the industry-leading 256-bit Advanced Encryption Standard (AES-256) algorithm. This is a fully managed encryption process: Microsoft performs key management, rotation, and compliance with key standards. Customers with security and compliance requirements can take advantage of this feature now.
