Importing and Using your Email or Personal Authentication certificate with Windows Live Mail

• If you originally applied for the certificate on the same computer as your Windows Live Mail then it should already be installed. You can skip straight to 'Signing and Encrypting'.

• If your certificate is not already installed on the computer you are using, then please export it from the machine on which it resides using one of the browsers listed on the CPAC main page. You then need to transfer it to this computer (email it to yourself or save the certificate file to USB then copy over). You can then follow the 'import' instructions in this document.

Signing and Encrypting Mails

• Signing an email ensures the recipient knows the email has come from you and informs them that it has not been modified in transit.

• Encrypting an email ensures that only the recipient can read the email content and attachments.

Note: In order to encrypt mail, you must first have your recipient’s email certificate in your certificate store. To obtain their certificate, you need to get your contact to send you a signed email. Upon receipt of the signed mail, their certificate will be automatically imported into your certificate store and you will be able to sign/encrypt mail to that person.
