Tips For Using A PKI Certificate For Outlook Email

One of the most important things that Comodo is able to offer is online security for everyone. We offer several products that are free of charge to both businesses and individuals. With our SSL/TLS products, we offer a free 90 day SSL (Secure Sockets Layer) certificate to protect your domain.

This will allow you to provide trust and assurance for your customer that your website is safe to personal information as well as financial information in the form of credit and debit cards or even information about your financial institution for e-checks or setting up automatic withdrawals or payments.

These SSL/TLS products, in the form of SSL certificates all use Public Key Infrastructure. This is a framework for the security that is developed through the use of the key pairs as well as certificates from trusted Certificate Authorities like Comodo.

At Comodo, we also think it is important to provide that same level of security to your email. If you use Outlook for your personal email, we offer a PKI certificate for Outlook for personal use that is completely free of charge. This is the same type of cert that is offered to businesses using Outlook or other forms of email clients including Windows Live Mail, Thunderbird, Mac OS X Mail, Apple Mail, or even Eudora or Mozilla SeaMonkey.

Obtaining the Free Personal Use PKI Certificate for Outlook

Getting your free PKI certificate through Comodo is a very simple process. You will need to provide some basic information to get started and so we can verify the email is connected to you and it is valid. This prevents someone from fraudulently applying for a PKI certificate to your email account.

The information you will need to provide includes your first name, last name and your email address. This email address will be the Outlook address you want to be able to digitally sign and encrypt. If you have more than one email address, you cannot combine them on one certificate, it is a single email address that is covered with each PKI certificate for Outlook.

You will also choose the key size for your private key. The larger the key size, which is provided when you select the option "High Grade" will give you increased security. This is the best option but, if you just need encryption without digital signatures, the medium grade is also more than safe and secure.

On the next block of text on the Application for the Secure Email cert, you will be asked to provide a revocation password. It is a good idea to make a note of the password as this will be required should you need to revoke the certificate prior to the expiry date on the certificate.

Revocation may be required if your email account become compromised or the private key or certificate is somehow compromised. It should also be completed if you stop using the account for some reason.

Next Steps

Once you have your PKI certificate for Outlook, you will need to assign it to your email account. This is where you should use our knowledgebase to find the step-by-step instructions based on your version of Outlook. Each version is a little bit different so having the right instructions will help to streamline the process.

You will not need to enter any code or complicated commands into the system. Instead, using the menu from the Outlook page, you will just click through the options and highlight the Comodo Personal Authentication Certificate that you have installed.

It is possible to set it up to do both encryption as well as digital signatures. This is the best option as you can leave both as manual options and use them as necessary for your personal mail. The other common option is to set up the system to automatically encrypt everything, protecting all email you sent but not adding the digital signature.

You will need to have the recipient's digital certificate as well before you can encrypt using their public key. Just ask them to send you an encrypted message and Outlook will automatically enter the certificate in the certificate store assigned to their email account.
