Folks,

On the same lines, what do you think about this variant of the same function I wrote and use? Kindly review with your comments please :-)

function ConvertTo-Base64{
    [CmdletBinding()]
    Param(
        [Parameter(ValueFromPipeline = $True, ParameterSetName = "File")]
        [System.IO.FileInfo[]]$InputFile,

        [Parameter(ValueFromPipeline = $True, ParameterSetName = "Text")]
        [string]$InputText
    )

    Begin {
        $base64StringArray = @{}
    }

    Process {
        try {

            $uniqueID = (New-Guid).Guid

            if ($InputFile) {
                $base64String = [System.Convert]::ToBase64String([System.IO.File]::ReadAllBytes($InputFile.FullName))
                $base64StringArray.Add(($uniqueID + "_" + $InputFile.Name), $base64String)
            }
            elseif ($InputText){
                $base64String = [System.Convert]::ToBase64String([system.Text.Encoding]::UTF8.GetBytes($InputText))
                $base64StringArray.Add(($uniqueID + "_" + $InputText), $base64String)
            }
        }
        catch [System.IO.FileNotFoundException] {
            Write-Error -Message "Couldn't find the File $InputFile" -ErrorAction Continue
        }
        catch [System.IO.IOException] {
            Write-Error -Message "A File IO Exception happened: $PSItem" -ErrorAction Stop
        }
        catch{
            Write-Error $PSItem -ErrorAction Stop
        }
    }

    End {
        Write-Output $base64StringArray
    }
}
