Powershell - Manage file integrity with a catalogue file
To support me, you can subscribe to the channel, share and like the videos, disable your ad blocker or make a donation. Thank you!
Hello,
It is very easy to check file integrity in PowerShell using a catalogue file which works in the same way as driver catalogue files.
The catalogue contains a fingerprint (hash) of the files contained in the folder specified when the catalogue was created.
If a file has been altered/modified then the hash changes, the catalogue test will encounter a failure.
This is not mandatory but you can sign the catalogue.
# Catalogue$CatalogueName = 'demo.cat'$Path = 'c:\demo'$CatalogueFile = New-FileCatalog -CatalogFilePath "$Path\$CatalogueName" -Path $Path -CatalogVersion 2
# Test the catalogueTest-FileCatalog -Path $path -CatalogFilePath "$path\$CatalogueName"
# Display files and hashes$result = Test-FileCatalog -Path $path -CatalogFilePath "$path\$CatalogueName"$result$result.PathItems
# Optional# Creation of the signing certificateNew-SelfSignedCertificate -Subject "CN=Guillaume" -Type CodeSigningCert -HashAlgorithm sha256 -CertStoreLocation Cert:\LocalMachine\My
# Certificate to sign the catalogue$Certificate = Get-ChildItem -Path Cert:\LocalMachine\My -CodeSigningCert
# Sign the catalogueSet-AuthenticodeSignature -Certificate $Certificate -FilePath $CatalogueFile -TimestampServer http://timestamp.digicert.comRelated links
