I do not fully understand about the size of what the files were and why they differ.. I will be glad of any help.

andyoknen commented 5 years ago

I think I understand what the problem is, in the latest.yml for Windows is not added to the size of the blockmap file. Now I have another problem, the SHA512 hash does not match. This is partly due to the fact that differential loading does not take into account the file signature..

By the way, I use the regular way of signing exe (with pfx). Can be blockmap is created before the signing?

"certificateFile": ....,
"certificatePassword": .....,
"publisherName": ......,
"rfc3161TimeStampServer": "http://timestamp.globalsign.com/scripts/timstamp.dll",
"signingHashAlgorithms": [
    "sha256"
]

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?
