This header is returned so that the client can check for message content integrity. The value of this header is computed by the Blob service; it is not necessarily the same value specified in the request headers.

If the blob has an MD5 hash and this operation is to read the full blob, this response header is returned so that the client can check for message content integrity.

The SHA-256 hash of the encryption key used to encrypt the block. This header is only returned when the block was encrypted with a customer-provided key.

Returns the name of the encryption scope used to encrypt the blob contents and application metadata. Note that the absence of this header implies use of the default account encryption scope.

The value of this header is set to true if the contents of the request are successfully encrypted using the specified algorithm, and false otherwise.
