title: Is it possible to compute an object's checksum from within Google Cloud Platform?
body: <p>Basically all I want to do is run <code>sha1sum my-bucket/my-object</code> so that I can compare the object's digest to the digest of a copy of the object stored on my local drive. </p>
  
  <p><code>gsutil</code> doesn't appear to be able to do this, and from reading all of Google's docs, there doesn't appear to be a simple way to do this. </p>
  
  <p>Am I missing something? Would I have to run a VM in Compute Engine and access the object that way? </p>
  
  <p>I'm not very familiar with Google's platform so forgive me if this is a silly question. Thanks for any help!</p>
