CPAC: Sign and encrypt email and documents quickly and easily

The Comodo Personal Authentication Certificate asserts personal identity and encrypts critical files and emails with just a few quick clicks of the mouse. Whether you’re with a large corporation or just a private individual, the ability to digitally sign and encrypt your email and documents is a boon to both privacy and security. Each Comodo Personal Authentication Certificate comes with a unique cryptographic key that can affix your own unique digital signature to email and documents, ensuring the recipient knows exactly who it’s coming from. Comodo Personal Authentication Certificates can encrypt your files and email so that only the intended parties can access them, too. They can also be used for two-factor authentication.

CPACs are one of the best ways to prevent Business Email Compromises, by ensuring employees only open email from verified senders. Best of all Comodo Personal Authentication Certificates integrate easily with all major Operating Systems and email clients, making them easy to install and even easier to use.

Encryption Strength

Comodo Personal Authentication Certificates come with 2048-bit signature keys that can affix a unique digital signature to any email or document. Users will also have the option to encrypt sensitive email and critical files to ensure their security. All Comodo Personal Authentication Certificates meet or exceed the encryption standards set forth by the National Institute for Standards in Technology (US) and the CA/Browser Forum (Industry).

Fast and Easy Validation

Comodo Personal Authentication Certificates are available at three different assurance levels, not unlike DV, OV and EV for SSL/TLS certificates. From Basic to Enterprise, the decision comes down to how much identity you want to assert, just a little (CPAC Basic) or complete identity (CPAC Enterprise). See for yourself.

Cheap Price is the cost leader for digital certificates, and not just SSL/TLS certificates, either. Nobody sells Comodo Personal Authentication Certificates for lower prices than we do. In fact, we guarantee it. Find a better price and we’ll beat it. That’s just how we roll.

"Very fast delivery. Installation was easy with no problems. If you are installing a wildcard SSL certificate on cPanel, you need to specify the actual domain name, don't try to install it on * , you have to install it on each subdomain such as,,..etc. Use the same certificate for each subdomain you install. Good luck!"
