I'm trying to optimize package installation process and looking for a solution to create a hash of Sitecore update package that will not take into account attributes of the files added to this package. I do not care about modification dates and file permissions etc. Only content.
Hash should be based purely on the content of this package, but the problem is that it contains multiple archives in it. Is there any "nice" way to get this hash?
PowerShell Get-FileHash could get a hash of one file content, but not in case of archived folder.
