This function makes it a one-step process. You're actually allowed to pass in `$null` and an empty string. If you do, you'll get `$null` and an empty string back. .LINK ConvertFrom-Base64 .EXAMPLE ConvertTo-Base64 -Value 'Encode me, please!' Encodes `Encode me, please!` into a base-64 string. .EXAMPLE ConvertTo-Base64 -Value 'Encode me, please!' -Encoding ([Text.Encoding]::ASCII) Shows how to specify a custom encoding in case your string isn't in Unicode text encoding. .EXAMPLE 'Encode me!' | ConvertTo-Base64 Converts `Encode me!` into a base-64 string. #> [CmdletBinding()] param( [Parameter(Mandatory=$true,ValueFromPipeline=$true)] [AllowNull()] [AllowEmptyString()] [string[]] # The value to base-64 encoding. $Value, [Text.Encoding] # The encoding to use. Default is Unicode. $Encoding = ([Text.Encoding]::Unicode) ) process { $Value | ForEach-Object { if( $_ -eq $null ) { return $null } $bytes = $Encoding.GetBytes($_) [Convert]::ToBase64String($bytes) } } } |
