Syntax

Export-Certificate
      [-Type <CertType>]
      [-NoClobber]
      [-Force]

Description

The Export-Certificate cmdlet exports a certificate from a certificate store to a file. The private key is not included in the export. If more than one certificate is being exported, then the default file format is SST. Otherwise, the default format is CERT. Use the Type parameter to change the file format.

Examples

EXAMPLE 1

$cert = Get-ChildItem -Path Cert:\CurrentUser\My\EEDEF61D4FF6EDBAAD538BB08CCAADDC3EE28FF

Export-Certificate -Cert $cert -FilePath C:\Certs\user.sst -Type SST

This example exports a certificate to the file system as a Microsoft serialized certificate store without its private key.

EXAMPLE 2

$cert = Get-ChildItem -Path Cert:\CurrentUser\My\EEDEF61D4FF6EDBAAD538BB08CCAADDC3EE28FF

Export-Certificate -Cert $cert -FilePath C:\Certs\user.cer

This example exports a certificate to the file system as a DER-encoded .cer file without its private key.

EXAMPLE 3

$cert = Get-ChildItem -Path Cert:\CurrentUser\My\EEDEF61D4FF6EDBAAD538BB08CCAADDC3EE28FF

Export-Certificate -Cert $cert -FilePath C:\Certs\user.p7b -Type p7b

This example exports a certificate to the file system as a PKCS#7-formatted .p7b file without its private key.

EXAMPLE 4

Get-ChildItem -Path Cert:\CurrentUser\My |
    Export-Certificate -FilePath C:\Certs\allcerts.sst -Type SST

This example exports all certificates under the Cert:\CurrentUser\My store into a Microsoft serialized certificate store allcerts.sst.

Parameters

-Cert

Specifies one or more certificates to be exported to a file. A single certificate object, an array of certificate objects, or a path to one or more certificates in a certificate store can be specified.

Type:Microsoft.CertificateServices.Commands.Certificate
Position:Named
Default value:None
Required:True
Accept pipeline input:True
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 location where the exported certificate will be stored.

Type:String
Aliases:FullName
Position:Named
Default value:None
Required:True
Accept pipeline input:False
Accept wildcard characters:False

-Force

Specifies that the exported certificate file will overwrite an existing certificate file, even if it has the Read-only attribute set. The NoClobber parameter takes precedence over this parameter when both are used.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-NoClobber

Prevents an exported certificate file from overwriting an existing certificate file. This parameter takes precedence over the Force parameter, which permits this cmdlet to overwrite an existing certificate file, even if it has the Read-only attribute set.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Type

Specifies the type of output file for the certificate export as follows.

  • SST: A Microsoft serialized certificate store (.sst) file format which can contain one or more certificates. This is the default value for multiple certificates.

  • CERT: A .cer file format which contains a single DER-encoded certificate. This is the default value for one certificate.

  • P7B: A PKCS#7 file format which can contain one or more certificates.

Type:Microsoft.CertificateServices.Commands.CertType
Accepted values:SST, CERT, P7B
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-WhatIf

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

Type:SwitchParameter
Aliases:wi
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

Inputs

X509Certificate2

A Certificate object can be piped into to this cmdlet.

Outputs

FileInfo

The FileInfo object contains the information about the certificate file.
