   md5 computation time benchmark (on macbook with ssd):
   
   (md5 compute/ total time) <- total time = IO(read contents from file) + md5 
hash computation
   1 mb: 17 / 20 ms
   10 mb: 54 / 62 ms
   100 mb: 402 / 462 ms
   1000 mb: 2998 / 3497 ms
   
   So, `computing md5 hash on 1GB file adds about 3 seconds.` Since this adds 
non-trivial overheads (depending on the use case), I updated the code to make 
md5 check configurable.
