function Test-IgugaChecksumFile { <# .SYNOPSIS Validate checksum file .DESCRIPTION Validate a give checksum file .PARAMETER FilePath Sets the path to a given checksum file .PARAMETER BasePath Used with Validate mode, sets the base path. This parameter is usefull when the paths inside of the checksum file are relative and the file being validated is located in a not related path. .PARAMETER Algorithm Sets the hashing algorithm to be used in the checksum validation. The allowed algotithms are: MD5, SHA1, SHA256, SHA384 and SHA512 .PARAMETER Silent Omitte the progress status .EXAMPLE # Perform a validate operation on a checksum file Test-IgugaChecksumFile -Path C:\Test\SHA512SUMS.txt -Algorithm SHA512 #> [OutputType([IgugaValidateResult[]])] [CmdletBinding()] Param( [Parameter(Position = 0, Mandatory = $true, HelpMessage = "The path to a given file checksum file")] [string] $FilePath, [string] $BasePath, [ValidateSet("MD5", "SHA1", "SHA256", "SHA384", "SHA512")] [string] $Algorithm = "SHA256", [switch] $Silent ) $Results = @() $WindowsDirSep = [System.IO.Path]::DirectorySeparatorChar $LinuxDirSep = [System.IO.Path]::AltDirectorySeparatorChar if ($PSBoundParameters.ContainsKey("BasePath") -and -not([string]::IsNullOrWhiteSpace($BasePath))) { if (-not(Test-Path -LiteralPath $BasePath -PathType Container)) { throw [IgugaError]::PathNotFound($Script:LocalizedData.ErrorBasePathNotFound, $BasePath) } $BasePath = Get-IgugaCanonicalPath -Path $BasePath } if (Test-Path -LiteralPath $FilePath -PathType Leaf) { $runningChar = "/" Get-Content -LiteralPath $FilePath | ForEach-Object { if (-not($Silent.IsPresent)) { $runningChar = if ($runningChar -eq "/") { "\" } else { "/" } Write-Progress -Activity $($Script:LocalizedData.ValidateOpProgressMessage -f $FilePath) -Status $($Script:LocalizedData.ValidateOpProgressStatus -f $runningChar) } $SplitChecksum = $_.Split(" ", 2) $CurrentStoredHash = $SplitChecksum[0].Trim().ToUpper() $CurrentStoredFilePath = $SplitChecksum[1].Trim() # Check if the file path is relative if (-not([System.IO.Path]::IsPathRooted($CurrentStoredFilePath))) { if ([string]::IsNullOrWhiteSpace($BasePath)) { $BasePath = (Get-Item -LiteralPath $FilePath).Directory.FullName } $CurrentStoredFilePath = Join-Path -Path $BasePath -ChildPath $CurrentStoredFilePath } $CurrentStoredFilePath = $CurrentStoredFilePath.Replace($WindowsDirSep, $LinuxDirSep).TrimEnd($LinuxDirSep) if (Test-Path -LiteralPath $CurrentStoredFilePath -PathType Leaf) { $ReturnedHash = (Get-IgugaChecksum -FilePath $CurrentStoredFilePath -Algorithm $Algorithm).Hash if ($ReturnedHash.Equals($CurrentStoredHash) ) { $Results += [IgugaValidateResult]::new($CurrentStoredFilePath, "PASS", $CurrentStoredHash, $ReturnedHash) } else { $Results += [IgugaValidateResult]::new($CurrentStoredFilePath, "FAIL", $CurrentStoredHash, $ReturnedHash) } } else { $Results += [IgugaValidateResult]::new($CurrentStoredFilePath, "NOT_FOUND") } } if (($Results.Length -gt 0) -and -not($Silent.IsPresent)) { Write-Progress -Activity $Script:LocalizedData.ValidateOpProgressCompleted -Completed } } else { throw [IgugaError]::PathNotFound($Script:LocalizedData.ErrorPathNotFound, $FilePath) } Write-Output $Results -NoEnumerate } |
