hi,all why we use sha256 instead md5 in chunk based backup-driver , in the current file chunkeddriver.py, we have object_sha256['sha256s'] list to store all the sha256 value of sha_block_size data , why we do not use md5 ,md5 is faster compute than sha256,and we all use the md5 value in _backup_chunk too, so we just need to compute one time and used in two diffrent place,it save much time
