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.
Examples
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.
Parameters
-Cert
Specifies the path to the certificate to be exported.
Type: | Certificate |
Aliases: | PsPath |
Position: | 0 |
Default value: | None |
Required: | True |
Accept pipeline input: | True |
Accept wildcard characters: | False |
-ChainOption
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.
Type: | ExportChainOption |
Accepted values: | BuildChain, EndEntityCertOnly, PfxDataOnly |
Position: | Named |
Default value: | BuildChain |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-Confirm
Prompts you for confirmation before running the cmdlet.
Type: | SwitchParameter |
Aliases: | cf |
Position: | Named |
Default value: | False |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-FilePath
Specifies the path for the PFX file to be exported.
Type: | String |
Position: | 1 |
Default value: | None |
Required: | True |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-Force
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.
Type: | SwitchParameter |
Position: | Named |
Default value: | False |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-NoClobber
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.
Type: | SwitchParameter |
Position: | Named |
Default value: | False |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-NoProperties
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.
Type: | SwitchParameter |
Position: | Named |
Default value: | False |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-Password
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.
Type: | SecureString |
Position: | Named |
Default value: | None |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-PFXData
Specifies a PFXData object that contains one or more certificates from a PFX file.
Type: | PfxData |

Accept pipeline input: | True |
Accept wildcard characters: | False |
-ProtectTo

Type: | String[] |
Position: | Named |
Default value: | None |
Required: | False |

Position: | Named |
Default value: | False |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
Inputs
The X509Certificate2[] object is an array of certificate objects.
Outputs
The FileInfo object contains the information about the PFX file.
