.SYNOPSIS Converts a string to a base64 encoded string. .DESCRIPTION Converts a string to a base64 encoded string. .PARAMETER String A string object for conversion. .PARAMETER MemoryStream A MemoryStream object for conversion. .PARAMETER Encoding The encoding to use for conversion. Defaults to UTF8. Valid options are ASCII, BigEndianUnicode, Default, Unicode, UTF32, UTF7, and UTF8. .EXAMPLE $string = 'A string' ConvertTo-Base64 -String $string QSBzdHJpbmc= .EXAMPLE $string = 'A string' $string | ConvertTo-Base64 QSBzdHJpbmc= .EXAMPLE $string = 'A string' ConvertTo-Base64 -String $string -Encoding Unicode QQAgAHMAdAByAGkAbgBnAA== .EXAMPLE $string = 'A string' $string | ConvertTo-Base64 -Encoding Unicode QQAgAHMAdAByAGkAbgBnAA== .EXAMPLE $string1 = 'A string' $string2 = 'Another string' ConvertTo-Base64 -String $string1,$string2 QSBzdHJpbmc= QW5vdGhlciBzdHJpbmc= .EXAMPLE $string1 = 'A string' $string2 = 'Another string' $string1,$string2 | ConvertTo-Base64 QSBzdHJpbmc= QW5vdGhlciBzdHJpbmc= .EXAMPLE $string1 = 'A string' $string2 = 'Another string' ConvertTo-Base64 -String $string1,$string2 -Encoding Unicode QQAgAHMAdAByAGkAbgBnAA== QQBuAG8AdABoAGUAcgAgAHMAdAByAGkAbgBnAA== .EXAMPLE $string1 = 'A string' $string2 = 'Another string' $string1,$string2 | ConvertTo-Base64 -Encoding Unicode QQAgAHMAdAByAGkAbgBnAA== QQBuAG8AdABoAGUAcgAgAHMAdAByAGkAbgBnAA== .EXAMPLE $string = 'A string' $stream = [System.IO.MemoryStream]::new() $writer = [System.IO.StreamWriter]::new($stream) $writer.Write($string) $writer.Flush() ConvertTo-Base64 -MemoryStream $stream QSBzdHJpbmc= .EXAMPLE $string = 'A string' $stream = [System.IO.MemoryStream]::new() $writer = [System.IO.StreamWriter]::new($stream) $writer.Write($string) $writer.Flush() $stream | ConvertTo-Base64 QSBzdHJpbmc= .EXAMPLE $string1 = 'A string' $stream1 = [System.IO.MemoryStream]::new() $writer1 = [System.IO.StreamWriter]::new($stream1) $writer1.Write($string1) $writer1.Flush() $string2 = 'Another string' $stream2 = [System.IO.MemoryStream]::new() $writer2 = [System.IO.StreamWriter]::new($stream2) $writer2.Write($string2) $writer2.Flush() ConvertTo-Base64 -MemoryStream $stream1,$stream2 QSBzdHJpbmc= QW5vdGhlciBzdHJpbmc= .EXAMPLE $string1 = 'A string' $stream1 = [System.IO.MemoryStream]::new() $writer1 = [System.IO.StreamWriter]::new($stream1) $writer1.Write($string1) $writer1.Flush() $string2 = 'Another string' $stream2 = [System.IO.MemoryStream]::new() $writer2 = [System.IO.StreamWriter]::new($stream2) $writer2.Write($string2) $writer2.Flush() $stream1,$stream2 | ConvertTo-Base64 QSBzdHJpbmc= QW5vdGhlciBzdHJpbmc= .OUTPUTS [String[]] .LINK http://convert.readthedocs.io/en/latest/functions/ConvertTo-Base64/ #> function ConvertTo-Base64 { [CmdletBinding( DefaultParameterSetName = 'String', HelpUri = 'http://convert.readthedocs.io/en/latest/functions/ConvertTo-Base64/')] param ( [Parameter( Mandatory = $true, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true, ParameterSetName = 'String')] [ValidateNotNullOrEmpty()] [String[]] $String, [Parameter( Mandatory = $true, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true, ParameterSetName = 'MemoryStream')] [ValidateNotNullOrEmpty()] [System.IO.MemoryStream[]] $MemoryStream, [ValidateSet('ASCII', 'BigEndianUnicode', 'Default', 'Unicode', 'UTF32', 'UTF7', 'UTF8')] [String] $Encoding = 'UTF8' ) begin { $userErrorActionPreference = $ErrorActionPreference } process { switch ($PSCmdlet.ParameterSetName) { 'String' { $splat = @{ Encoding = $Encoding ErrorAction = $userErrorActionPreference } foreach ($s in $string) { ConvertFrom-StringToBase64 -String $s @splat } break } 'MemoryStream' { $splat = @{ Encoding = $Encoding ErrorAction = $userErrorActionPreference } foreach ($m in $MemoryStream) { ConvertFrom-MemoryStreamToBase64 -MemoryStream $m @splat } break } default { Write-Error -Message 'Invalid ParameterSetName' -ErrorAction $userErrorActionPreference break } } } } |
