NAME Export-PfxCertificate



SYNOPSIS

Exports a certificate or a PFXData object to a Personal Information Exchange (PFX) file.





SYNTAX

Export-PfxCertificate [-Cert] <Certificate> [-FilePath] <String> [-ChainOption {BuildChain | EndEntityCertOnly | PfxDataOnly}] [-Force] [-NoClobber]

[-NoProperties] [-Password <SecureString>] [-ProtectTo <String[]>] [-Confirm] [-WhatIf] [<CommonParameters>]



Export-PfxCertificate [-PFXData] <PfxData> [-FilePath] <String> [-ChainOption {BuildChain | EndEntityCertOnly | PfxDataOnly}] [-Force] [-NoClobber]

[-NoProperties] [-Password <SecureString>] [-ProtectTo <String[]>] [-Confirm] [-WhatIf] [<CommonParameters>]





DESCRIPTION

The Export-PfxCertificate cmdlet exports a certificate or a PFXData object to a Personal Information Exchange (PFX) file. By default, extended

properties and the entire chain are exported.



Delegation may be required when using this cmdlet with Windows PowerShell???? remoting and changing user configuration.





PARAMETERS

-Cert <Certificate>

Specifies the path to the certificate to be exported.



Required? true

Position? 1

Default value none

Accept pipeline input? true (ByPropertyName)

Accept wildcard characters? false



-ChainOption [<ExportChainOption>]

Specifies the options for building a chain when exporting certificates. The acceptable values for this parameter are:



-- BuildChain: Certificate chain for all end entity certificates will be built and included in the export. This option is valid for both PfxData

and Cert parameters. In the case of PfxData parameter, the collection of all PFX certificates will be used as an additional store.



-- EndEntityCertOnly: Only end entity certificates are exported without any chain. This option is valid for both the PfxData and the Cert

parameters.



-- PfxDataOnly: Certificates contained in PFXData objects will be exported with no chain building. This option is only valid when the PfxData

parameter is used.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-FilePath <String>

Specifies the path for the PFX file to be exported.



Required? true

Position? 2

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-Force [<SwitchParameter>]

Specifies that the provided PFX file should be overwritten, even if the Read-only attribute is set on the file. By default, this cmdlet overwrites

existing PFX files without warning, unless the Read-only or hidden attribute is set or the NoClobber parameter is used in the cmdlet.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-NoClobber [<SwitchParameter>]

Specifies that if the PFX file already exists, it should not be over written. This parameter takes precedence over the Force parameter, which

permits this cmdlet to overwrite a PFX file even if it has the Read-only attribute set.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-NoProperties [<SwitchParameter>]

Specifies whether the extended properties for a certificate are exported. If this parameter is specified, then extended properties are not included

with the export. By default, all extended properties are included in the exported file.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-PFXData <PfxData>

Specifies a PFXData object that contains one or more certificates from a PFX file.



Required? true

Position? 1

Default value none

Accept pipeline input? true (ByValue)

Accept wildcard characters? false



-Password [<SecureString>]

Specifies the password used to protect the exported PFX file. The password should be in the form of secure string. Either the ProtectTo or this

parameter must be specified, or an error will be displayed.



Required? false

Position? named

Default value none

Accept pipeline input? false

Accept wildcard characters? false



-ProtectTo [<String[]>]

Specifies an array of strings for the username or group name that can access the private key of PFX file without any password. This requires a

Windows Server???? 2012 domain controller. Either the Password or this parameter must be specified, or an error will be displayed.

<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug,

ErrorAction, ErrorVariable, WarningAction, WarningVariable,

OutBuffer, PipelineVariable, and OutVariable. For more information, see

about_CommonParameters (https:/go.microsoft.com/fwlink/?LinkID=113216).



INPUTS

System.Security.Cryptography.X509Certificates.X509Certificate2[]



The X509Certificate2[] object is an array of certificate objects.





OUTPUTS

System.IO.FileInfo



The FileInfo object contains the information about the PFX file.





EXAMPLE 1



PS C:\\>$mypwd = ConvertTo-SecureString -String "1234" -Force ????????AsPlainText







PS C:\\>Get-ChildItem -Path cert:\\localMachine\\my\\5F98EBBFE735CDDAE00E33E0FD69050EF9220254 | Export-PfxCertificate -FilePath C:\\mypfx.pfx -Password $mypwd



This example exports a certificate from the local machine store to a PFX file which includes the entire chain and all external properties.





EXAMPLE 2



PS C:\\>$mypwd = ConvertTo-SecureString -String "1234" -Force ????????AsPlainText







PS C:\\>Get-ChildItem -Path cert:\\LocalMachine\\my | Export-PfxCertificate -FilePath C:\\mypfx.pfx -Password $mypwd



This example exports all certificates under the My store for the machine account into one file named mypfx.pfx. In order for this cmdlet to succeed, all

keys need to be exportable.





EXAMPLE 3



PS C:\\>$mypwd = ConvertTo-SecureString -String "1234" -Force ????????AsPlainText







PS C:\\>Export-PfxCertificate ????????Cert cert:\\currentuser\\my\\5F98EBBFE735CDDAE00E33E0FD69050EF9220254 ????????FilePath c:\\myexport.pfx -ChainOption

EndEntityCertOnly -NoProperties -Password $mypwd



This example exports a certificate from the current user store with no chain and no external properties





EXAMPLE 4



PS C:\\>$a = Get-ChildItem -Path cert:\\localMachine\\my

Export-PfxCertificate ????????Cert $a[1] ????????FilePath C:\\myexport.pfx -ProtectTo "contoso\\billb99, contoso\\johnj99"



This example exports a certificate from the current machine store. Both user accounts, contos\\billb99 and contos\\johnj99, can access this PFX with no

password. A Windows???? 8 DC for key distribution is required.





EXAMPLE 5



PS C:\\>$a = Get-ChildItem -Path cert:\\localMachine\\my







PS C:\\>$mypwd = ConvertTo-SecureString -String "1234" -Force ????????AsPlainText







PS C:\\>Export-PfxCertificate ????????Cert $a[1] ????????FilePath C:\\myexport.pfx -ProtectTo "contoso\\billb99, contoso\\johnj99" -Password $mypwd



This example exports a certificate from the current machine store. Both user accounts, johnj99 and billb99, can access this PFX file with no password.

For everyone else, they need to use 1234 as a password. A Windows 8 DC for key distribution is required.





EXAMPLE 6



PS C:\\>$NewPwd = ConvertTo-SecureString -String "abcd" -Force ????????AsPlainText







PS C:\\>$mypfx = Get-PfxData ????????FilePath C:\\mypfx.pfx -Password $Oldpwd







PS C:\\>Export-PfxCertificate -PFXData $mypfx ????????FilePath C:\\mypfx2.pfx -Password $NewPwd



This example changes an existing password for a PFX file from $OldPwd to $NewPwd.
