function Export-Credential { <# .SYNOPSIS Export and encrypt a credential object with a static keyphrase .DESCRIPTION Export and encrypt a credential object with a static keyphrase This Cmdlet lets you save credentials via a static password to a text file. In contrast to Export-CliXml the SecureString in the Credential object is not encrypted with the identity of the current user nbut with a static keyphrase and thus can be read by any other user (on any other machine) that also has access to the keyphrase. .INPUTS You can pipe a credential object to the Cmdlet. .EXAMPLE $cred.GetType() IsPublic IsSerial Name BaseType -------- -------- ---- -------- True True PSCredential System.Object $cred | Export-Credential .\Credential.xml -KeyPhrase P@ssw0rd Encrypts the PSCredential object with the keyphrase 'P@ssw0rd' to a file in the currenty directory. .LINK Online Version: http://dfch.biz/biz/dfch/PS/System/Utilities/Export-Credential/ .NOTES See module manifest for required software versions and dependencies at: http://dfch.biz/biz/dfch/PS/System/Utilities/biz.dfch.PS.System.Utilities.psd1/ #> [CmdletBinding( SupportsShouldProcess = $true , ConfirmImpact= 'Low' , HelpURI = 'http://dfch.biz/biz/dfch/PS/System/Utilities/Export-Credential/' )] Param ( # Specifies the full path and file name of the encrypted credential object [Parameter(Mandatory = $true, Position = 0)] [string] $Path , # Specifies the credential object to encrypt [Parameter(Mandatory = $true, ValueFromPipeline = $True, Position = 1)] [Alias('Credential')] [PSCredential] $InputObject , # Specifies a keyphrase of the encrypted credential object [Parameter(Mandatory = $false, Position = 2)] [Alias('Password')] [string] $KeyPhrase = [NullString]::Value ) BEGIN { $datBegin = [datetime]::Now; [string] $fn = $MyInvocation.MyCommand.Name; Log-Debug -fn $fn -msg ("CALL.
