function Get-DbaDatabaseEncryption { <# .SYNOPSIS Returns a summary of encryption used on databases passed to it. .DESCRIPTION Shows if a database has Transparent Data Encryption (TDE), any certificates, asymmetric keys or symmetric keys with details for each. .PARAMETER SqlInstance SQL Server name or SMO object representing the SQL Server to connect to. This can be a collection and receive pipeline input. .PARAMETER SqlCredential PSCredential object to connect as. If not specified, current Windows login will be used. .PARAMETER Database The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will be processed. .PARAMETER ExcludeDatabase The database(s) to exclude - this list is auto-populated from the server. .PARAMETER IncludeSystemDBs Switch parameter that when used will display system database information. .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 Author: Stephen Bennett, https://sqlnotesfromtheunderground.wordpress.com/ Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Get-DbaDatabaseEncryption .EXAMPLE Get-DbaDatabaseEncryption -SqlInstance DEV01 List all encryption found on the instance by database .EXAMPLE Get-DbaDatabaseEncryption -SqlInstance DEV01 -Database MyDB List all encryption found for the MyDB database. .EXAMPLE Get-DbaDatabaseEncryption -SqlInstance DEV01 -ExcludeDatabase MyDB List all encryption found for all databases except MyDB. .EXAMPLE Get-DbaDatabaseEncryption -SqlInstance DEV01 -IncludeSystemDBs List all encryption found for all databases including the system databases. #> [CmdletBinding()] param ([parameter(ValueFromPipeline, Mandatory = $true)] [Alias("ServerInstance", "SqlServer")] [DbaInstanceParameter[]]$SqlInstance, [PSCredential]$SqlCredential, [Alias("Databases")] [object[]]$Database, [object[]]$ExcludeDatabase, [switch]$IncludeSystemDBs, [Alias('Silent')] [switch]$EnableException ) process { foreach ($instance in $SqlInstance) { #For each SQL Server in collection, connect and get SMO object Write-Message -Level Verbose -Message "Connecting to $instance" try { Write-Message -Level Verbose -Message "Connecting to $instance" $server = Connect-SqlInstance -SqlInstance $instance -SqlCredential $SqlCredential } catch { Stop-Function -Message "Failure" -Category ConnectionError -ErrorRecord $_ -Target $instance -Continue } #If IncludeSystemDBs is true, include systemdbs #only look at online databases (Status equal normal) try { if ($Database) { $dbs = $server.Databases | Where-Object Name -In $Database } elseif ($IncludeSystemDBs) { $dbs = $server.Databases | Where-Object IsAccessible } else { $dbs = $server.Databases | Where-Object { $_.IsAccessible -and $_.IsSystemObject -eq 0 } } if ($ExcludeDatabase) { $dbs = $dbs | Where-Object Name -NotIn $ExcludeDatabase } } catch { Stop-Function -Message "Unable to gather dbs for $instance" -Target $instance -Continue } foreach ($db in $dbs) { Write-Message -Level Verbose -Message "Processing $db" if ($db.EncryptionEnabled -eq $true) { [PSCustomObject]@{ ComputerName = $server.NetName InstanceName = $server.ServiceName SqlInstance = $server.DomainInstanceName Database = $db.Name Encryption = "EncryptionEnabled (TDE)" Name = $null LastBackup = $null PrivateKeyEncryptionType = $null EncryptionAlgorithm = $null KeyLength = $null Owner = $null Object = $null ExpirationDate = $null } } foreach ($cert in $db.Certificates) { [PSCustomObject]@{ ComputerName = $server.NetName InstanceName = $server.ServiceName SqlInstance = $server.DomainInstanceName Database = $db.Name Encryption = "Certificate" Name = $cert.Name LastBackup = $cert.LastBackupDate PrivateKeyEncryptionType = $cert.PrivateKeyEncryptionType EncryptionAlgorithm = $null KeyLength = $null Owner = $cert.Owner Object = $cert ExpirationDate = $cert.ExpirationDate } } foreach ($ak in $db.AsymmetricKeys) { [PSCustomObject]@{ ComputerName = $server.NetName InstanceName = $server.ServiceName SqlInstance = $server.DomainInstanceName Database = $db.Name Encryption = "Asymmetric key" Name = $ak.Name LastBackup = $null PrivateKeyEncryptionType = $ak.PrivateKeyEncryptionType EncryptionAlgorithm = $ak.KeyEncryptionAlgorithm KeyLength = $ak.KeyLength Owner = $ak.Owner Object = $ak ExpirationDate = $null } } foreach ($sk in $db.SymmetricKeys) { [PSCustomObject]@{ Server = $server.name Instance = $server.InstanceName Database = $db.Name Encryption = "Symmetric key" Name = $sk.Name LastBackup = $null PrivateKeyEncryptionType = $sk.PrivateKeyEncryptionType EncryptionAlgorithm = $ak.EncryptionAlgorithm KeyLength = $sk.KeyLength Owner = $sk.Owner Object = $sk ExpirationDate = $null } } } } } } |
