> The MongoGridFSBlobStore implementation relies on using MD5 as the content hash, which is dangerous. This isn't a problem of GridFS itself, but of MongoGridFSBlobStore.
> For security reasons, we would need to use SHA-2 (or at least SHA-1). It doesn't look like it would be easy to change MongoGridFSBlobStore, because "md5" is used internally by GridFS (but not actually as the content hash).
> So either we make a bigger change to MongoGridFSBlobStore, or we remove it. I think we should remove it, as we have a good alternative (the MongoBlobStore, which uses SHA-256, but not GridFS).
