function ConvertTo-Base64String { <# .SYNOPSIS Converts a string, credential, or file contents to a base64 encoded string. .DESCRIPTION This function takes a string, credential (username and password), or file contents and converts it into a base64 encoded string. The user can specify the desired encoding format for the conversion. .PARAMETER Encoding Specifies the encoding format to be used for conversion. Default is "Default". Valid options are: Default, ASCII, BigEndianUnicode, Unicode, UTF32, UTF8, and UTF7. .PARAMETER String The string to be converted to a base64 encoded string. .PARAMETER Credential The credential object containing username and password. The function will convert them to a base64 encoded string. .PARAMETER Path The path to a file. The function will read the file contents and convert them to a base64 encoded string. .NOTES Author: Eric Meinders Version: 1.0 #> [cmdletbinding(DefaultParameterSetName = "String")] param ( [ValidateSet("Default","ASCII","BigEndianUnicode","Unicode","UTF32","UTF8","UTF7")] [Parameter(ParameterSetName = "String")] [Parameter(ParameterSetName = "Credential")] [String]$Encoding = "Default", [Parameter(Mandatory, Position = 0, ValueFromPipeline, ParameterSetName = "String")] [String]$String, [Parameter(Mandatory, ParameterSetName = "Credential")] [System.Management.Automation.PSCredential] $Credential, [Parameter(Mandatory, ParameterSetName = "File")] [ValidateScript({ if (!(Test-Path $_)) { throw "File does not exist" } if (!(Test-Path $_ -PathType Leaf)) { throw "The specified path must be a file" } return $true })] [System.IO.FileInfo]$Path ) function ConvertFrom-Byte ($in) { [System.Convert]::ToBase64String($in) } # Convert file contents to base64 if ($Path) { $byteArray = Get-Content -Path $Path -Encoding Byte ConvertFrom-Byte $byteArray return } # Convert credential to base64 if ($Credential) { $String = $Credential.UserName + ":" + $Credential.GetNetworkCredential().Password } # Convert string to base64 using specified encoding $byteArray = switch ($Encoding) { "Default" { [System.Text.Encoding]::Default.GetBytes($String) } "ASCII" { [System.Text.Encoding]::ASCII.GetBytes($String) } "BigEndianUnicode" { [System.Text.Encoding]::BigEndianUnicode.GetBytes($String) } "Unicode" { [System.Text.Encoding]::Unicode.GetBytes($String) } "UTF32" { [System.Text.Encoding]::UTF32.GetBytes($String) } "UTF8" { [System.Text.Encoding]::UTF8.GetBytes($String) } "UTF7" { [System.Text.Encoding]::UTF7.GetBytes($String) } } # Call the helper function to perform the actual conversion ConvertFrom-Byte $byteArray } |
