Hi @Ed Burke
Not sure if I understand your question fully. If you rename an RTB file to a ZIP file, you should be able to open it and see the images. At least in my case just tested it, still works at least on the board I tried.
As far as CHANGING anything in the file . . . well, checksums and all that.
Looking for something different?
Cheers, Ken
Hi @Gunja
I replied to your question in the other thread you posted in. Hope you find it helpful!

If there are to be encryption keys for any backup they must be provided to the client and not reside with Miro - this is security 101.
