How azcopy performs file consistency validation
Like azcopy, Microsoft's client for uploading large files to Blob, the md5 hash must be computed locally and uploaded to the blob properties along with the file, the blob service will commit this at the end of the process, returning an error if presents inconsistency in value.
Calculates the MD5 hash of the file content and saves it as the Content-MD5 property of the blob:
azcopy --put-md5 #

This library uses the concepts of the azcopy client for its implementation.
