[<CommonParameters>]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 SSTThis 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.cerThis 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 p7bThis 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 SSTThis example exports all certificates under the Cert:\CurrentUser\My store into a Microsoft
serialized certificate store allcerts.sst.

| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-Confirm
Prompts you for confirmation before running the cmdlet.

-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 |

| 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.cerfile 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 |
