Hashsum of uploaded movies/attachments

Does Shotgun store any hash sums (sha1, md5, etc) of uploaded content? If so, is there any way to access these, or could they be made accessible through a read-only field?

Thanks,

+1 on this question. We’re looking into solutions for identifying redundant/duplicate media uploads, accounting for the possibility of changing file names. One option that occurred to us was storing md5 in a custom field (calculated and populated by an event trigger). But it occurs to us that S3 should also provide access to this hash via its api. Although it’s questionable whether the shotgun makes the requisite keys to access the S3 bucket available to users. Anyone out there had any success tackling this particular issue?
