Export-DnsServerDnsSecPublicKey

Export-DnsServerDnsSecPublicKey

Parameter Set: DnsKey
Export-DnsServerDnsSecPublicKey [-ZoneName] <String> [-AsJob] [-CimSession <CimSession[]> ] [-ComputerName <String> ] [-Force] [-NoClobber] [-PassThru] [-Path <String> ] [-ThrottleLimit <Int32> ] [-UnAuthenticated] [-Confirm] [-WhatIf] [ <CommonParameters>]

Parameter Set: DS
Export-DnsServerDnsSecPublicKey [-ZoneName] <String> -DigestType <String[]> [-AsJob] [-CimSession <CimSession[]> ] [-ComputerName <String> ] [-Force] [-NoClobber] [-PassThru] [-Path <String> ] [-ThrottleLimit <Int32> ] [-UnAuthenticated] [-Confirm] [-WhatIf] [ <CommonParameters>]

Detailed Description

The Export-DnsServerDnsSecPublicKey cmdlet exports delegation signer (DS) or Domain Name System public key (DNSKEY) information for a Domain Name System Security Extensions (DNSSEC)–signed zone.

Parameters

-AsJob

-CimSession<CimSession[]>

Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.

-ComputerName<String>

Specifies a remote DNS server. You can specify an IP address or any value that resolves to an IP address, such as a fully qualified domain name (FQDN), host name, or NETBIOS name.

-DigestType<String[]>

Specifies an array of algorithms that the zone signing key uses to create the DS record. The acceptable values for this parameter are:
-- Sha1
-- Sha256
-- Sha384

-Force

Exports the signing key without prompting you for confirmation. By default, the cmdlet prompts you for confirmation before it proceeds.

-NoClobber

Specifies that the export operation does not overwrite an existing export file that has the same name.

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

-Path<String>

Specifies the absolute path that the cmdlet uses to place the keyset file. The cmdlet automatically names the file according to the zone name.

-ThrottleLimit<Int32>

Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.

-UnAuthenticated

Specifies that an unauthenticated user is running this cmdlet. The provider DNS server queries for the DS or DNSKEY information and exports the required data even if you do not have permissions to run the cmdlet on the remote DNS server.

-ZoneName<String>

Specifies the name of the primary zone for which the cmdlet exports the signing keys.

-Confirm

Prompts you for confirmation before running the cmdlet.

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

Outputs

The output type is the type of the objects that the cmdlet emits.

Examples

Example 1: Export a trust anchor to a file share

This command exports the trust anchor (DS record) for Contoso.com to a file share. A DNS administrator runs this command from the DNS server that hosts the zone Contoso.com and specifies that the zone signing key uses the SHA-1 algorithm to create the DS record.

This command creates Keyset-Contoso.com in \\MyDNSKeyShare\keys and writes the DS record in the Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DNS/DNS/DnsServerResourceRecord format.

PS C:\> Export-DnsServerDnsSecPublicKey -ComputerName "DNSDC1.Contoso.com" -ZoneName "Contoso.com" -Path "\\MyDNSKeyShare\keys" -PassThru -DigestType "Sha1"

Example 2: Export a trust anchor by using unauthorized access

This command exports a trust anchor (DNSKEY record) for Contoso.com to a file share. The DNS administrator who runs this command has no permissions to the DNS server that hosts the zone Contoso.com. This command specifies that the zone signing key uses the SHA-1 algorithm to create the DS record.

This command creates Keyset-Contoso.com in \\MyDNSKeyShare\keys and writes the DS record in the Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DNS/DNS/DnsServerResourceRecord format.

PS C:\> Export-DnsServerDnsSecPublicKey -ComputerName "DNSDC1.contoso.com" -ZoneName "Contoso.com" - Path "\\MyDNSKeyShare\keys" -PassThru -UnAuthorized -Force -DigestType "Sha1"

Example 3: Get the trust anchors for all the signed zones

This command gets the trust anchors for all the signed zones that are hosted on the DNS server Contoso.com. In this scenario the DNS Server is currently hosting signed zones for contoso.com, dinnernow.com and hrweb.net

The command uses a Foreach-Object cmdlet to export the trust anchors and pipe the results to the Get-DnsServerZone cmdlet.

This command creates a keyset file in the share for each signed zone that is hosted on the DNS server (Keyset-Contoso.com, Keyset-Dinnernow.com, Keyset-Hrweb.net) and writes the DNSKEY record in the Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/DNS/DNS/DnsServerResourceRecord format.

PS C:\> Get-DnsServerZone | ForEach-Object {Export-DnsServerDnsSecPublicKey -ComputerName "DNSDC1.Contoso.com" -ZoneName "Contoso.com" -Path "\\MyDNSKeyShare\keys" -PassThru -UnAuthorized -Force  }

Example 4: Import a trust anchor to a non-authorized DN server

The first command exports the trust anchor (DNSKEY record) for Contoso.com to the specified path, and stores the results in the $publicKey variable. The UnAuthenticated parameter indicates that the DNS administrator who runs this command has no permissions to the DNS server that hosts the zone Contoso.com.

The second command adds the first trust record that was exported from Contoso.com into a non-authoritative DNS server named DNSDC1.Contoso.com.

PS C:\> $publicKey = Export-DnsServerDnssecPublicKey -ZoneName "contoso.com" -Path "C:\" -PassThru -UnAuthenticated –Force

PS C:\> $publicKey[0].RecordData | Add-DnsServerTrustAnchor -Name "constoso.com" –ComputerName "DNSDC1.Contoso.com"
