Test-FileCatalog validates whether the hashes contained in a catalog file (.cat) matches the
hashes of the actual files in order to validate their authenticity.
This cmdlet is only supported on Windows.

Description
Test-FileCatalog validates the authenticity of files by comparing the file hashes of a catalog
file (.cat) with the hashes of actual files on disk. If it detects any mismatches, it returns the
status as ValidationFailed. Users can retrieve all this information by using the -Detailed
parameter. It also displays signing status of catalog in Signature property which is equivalent to
calling Get-AuthenticodeSignature cmdlet on the catalog file. Users can also skip any file during
validation by using the -FilesToSkip parameter.
This cmdlet is only supported on Windows.
Ejemplos
Example 1: Create and validate a file catalog
New-FileCatalog -Path $PSHOME\Modules\Microsoft.PowerShell.Utility -CatalogFilePath \temp\Microsoft.PowerShell.Utility.cat -CatalogVersion 2.0
Test-FileCatalog -CatalogFilePath \temp\Microsoft.PowerShell.Utility.cat -Path "$PSHOME\Modules\Microsoft.PowerShell.Utility\"
Valid
Example 2: Validate a file catalog with detailed output
Test-FileCatalog -Detailed -CatalogFilePath \temp\Microsoft.PowerShell.Utility.cat -Path "$PSHOME\Modules\Microsoft.PowerShell.Utility\"
Status : Valid
HashAlgorithm : SHA256

Entradas
DirectoryInfo
You can pipe a DirectoryInfo object representing the path to the files that need to be validated.
String
You can pipe a string representing the path to the files that need to be validated.

CatalogValidationStatus
By default, this cmdlet returns a CatalogValidationStatus object with a value of either Valid
or ValidationFailed.
CatalogInformation
When you use the Detailed parameter, the cmdlet returns a CatalogInformation object for each file, which can be used to analyze specific files that may or may not have passed validation, which hashes were expected vs. found, and the algorithm used in the catalog.
