The PKCS#12 file (or .p12 file) thus created can now be used to integrate your certificate into your e-mail programmes or to transfer it to your other computers. In MS Windows e.g., all you need is to double-click on this file (as well as Import… and several clicks on OK) to make the certificate known to the system and, at the same time, to use it in Outlook.
