To Import a Certificate

To import a certificate

1. Open the Certificates console for the user, computer, or service you want to manage.
2. Select a certificate store for the certificate type you want to import. For example, you might select the Personal store under Certificates (Local Computer).
3. On the Action menu, point to All Tasks and then click Import to start the Certificate Import Wizard.
4. Type the file name containing the certificate to be imported. (You can also click Browse and navigate to the file.)
5. If it is a PKCS #12 file, do the following:
   • Type the password used to encrypt the private key.
   • (Optional) If you want to be able to use strong  private key protection, select the Enable strong private key protection check box. Enabling strong private key protection will ensure that you are prompted for a password every time the private key is used. This is useful if you want to make sure that the private key is not used without your knowledge.
   • (Optional) If you want to back up or transport your keys at a later time, select the Mark key as exportable check box.
6. Do one of the following:
   • If the certificate should be automatically placed in a  certificate store based on the type of certificate, click Automatically       select the certificate store based on the type of certificate.
   • If you want to specify where the certificate is  stored, select Place all certificates in the following store,  click Browse, and choose the certificate store to use.
