Garage currently does not implement checking of the MD5 sum of the uploaded data, which should match the Content-MD5 header. Should be implemented.

This should be done for:

PutObject
UploadPart
anything else?

We should make sure that we implement this well enough so that the following is also verified: if a request to put an object contains a MD5 sum and the MD5 sum is part of the authenticated/signed request (AWS signatures v4 protocol), then we know that the data itself is authenticated properly by the signing key.
