Creating file checksums

Can anyone provide some information on creating/verifying file checksums with BrightScript objects? Within the list of public classes, I can see: roSyncSpec, roSyncPool, roSyncPoolEvent, roSyncPoolProgressEvent, roSyncPoolFiles but I was looking for a more direct method of generating and verifying SHA1 file checksums. Ideally, I would like to be able to work with SHA1 file hashes but without making use of the above classes. Also, there does not appear to be any accessible documentation on the above classes. Perhaps they provide access to the type of functionality I am looking for? Thanks

  You are looking to do the calculation directly on the brightsign? I'm not sure I understand what you are trying to do.
  
  Yes, you are correct those classes aren't documented.

  Yes, I would like to perform calculations on the BrightSign. In much the same way that the SyncPool classes seem to support BrightSign Network functionality, I would like to perform a small subset of those functions within my own programing. For example, I would like to download files using roURTransfer and then verify that I have downloaded the entire file from the server using some sort of file checksum. That is, unless there is another way to perform the same function?

  This has been requested, but isn't implemented. I don't have a timeline for this yet.
