Storage Service Encryption for Azure File Storage
Azure File Storage will be a fully managed service providing distributed and cross platform storage. Using Azure Files, IT organizations will be able to lift and shift their on-premises file shares to the cloud easily, without having to incur development costs to adopt cloud storage.
Azure Files will soon offer encryption of data at rest capability. When Storage Service Encryption for File storage is enabled, the data will be encrypted automatically. Microsoft will handle all the encryption, decryption, and key management in a fully transparent fashion. All data will be encrypted using 256-bit AES encryption, also known as AES-256, one of the strongest block ciphers available. Customers will be able to enable this feature on both the LRS and GRS redundancy types of File storage.
