function Export-DbaCredential { <# .SYNOPSIS Exports credentials INCLUDING PASSWORDS, unless specified otherwise, to sql file. .DESCRIPTION Exports credentials INCLUDING PASSWORDS, unless specified otherwise, to sql file. Requires remote Windows access if exporting the password. .PARAMETER SqlInstance Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2005 or higher. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential) .PARAMETER Credential Login to the target OS using alternative credentials. Accepts credential objects (Get-Credential) .PARAMETER Path The path to the exported sql file. .PARAMETER Identity The credentials to export. If unspecified, all credentials will be exported. .PARAMETER InputObject Allow credentials to be piped in from Get-DbaCredential .PARAMETER ExcludePassword Exports the SQL credential without any sensitive information. .PARAMETER InputObject Allow credentials to be piped in from Get-DbaCredential .PARAMETER Append Append to Path .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: Credential Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .EXAMPLE PS C:\> Export-DbaCredential -SqlInstance sql2017 -Path C:\temp\cred.sql Exports credentials, including passwords, from sql2017 to the file C:\temp\cred.sql #> [CmdletBinding()] param ( [Parameter(Mandatory, ValueFromPipeline)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [string[]]$Identity, [PSCredential]$SqlCredential, [PSCredential]$Credential, [string]$Path, [switch]$ExcludePassword, [switch]$Append, [Microsoft.SqlServer.Management.Smo.Credential[]]$InputObject, [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { try { Write-Message -Level Verbose -Message "Connecting to $instance." $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $sqlcredential -MinimumVersion 9 $InputObject += $server.Credentials } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } if ($Identity) { $InputObject = $InputObject | Where-Object Identity -in $Identity } if (!(Test-SqlSa -SqlInstance $instance -SqlCredential $sqlcredential)) { Stop-Function -Message "Not a sysadmin on $instance.
