The following sub sections detail the different Types of Certificate and the correct Class depending on your requirement.
Digi-SSLs™ are Secure Socket Layer [SSL] Certificates and are used for securing and authenticating the following:
Digi-SSLs™ are the most commonplace Digital Certificate in use today. Web sites and other servers use Digi-SSLs™ in their thousands each year. If your requirement is predominantly for SSL and SSL Management, we recommend the Digi-SSL™ Service. And to completely automate the entire life cycle of your SSL environment, see the Automated & Authenticated Certificate Delivery™ System
Digi-SSL™ provides you with two functions:
Every application for any class of Digi-SSL™ is subjected to the Triple-Check Validations™ procedure. This means that two or more Validations Officers physically check your details and entitlement to get the Digi-SSL™ before it is issued to you. This rigorous checking procedure protects you from someone else stealing your online identity because the Digi-Sign Triple-Check Validations™ has a 100% track record of never issuing a Digital Certificate to the wrong party. Once this Digi-SSL™ is put on your website, visitors know your site is genuine.
The same Digi-SSL™ that authenticates your site to visitors can also be used for encrypting data and it is here that the Xp/Xg and Xs difference occurs. The main difference between Xp/Xg & Xs is that the Digi-SSL™ Xs is for low/no value transactions and Xp/Xg is for corporate users and commercial websites.
The Digi-Sign Certificate Practice Statement [CPS] v3.7, Sub section 2.4.1.a and 5.32.1 both state that the maximum warranty associated with a Digi-SSL™ Xs certificate is €0.01. So if your information is worth more than €0.01 and you require warranty protection, you should only use the Xs Certificate to authenticate your website. This does not mean you can’t use the Xs for encrypting data, it only means that in the event of a fault in the Digi-SSL™, you have no warranty.
The maximum warranty associated with the Digi-SSL™ Xp or Xg Certificate is €10,000. The CPS v3.7, Sub section 2.4.1.b and 5.32.2, both state clearly that this is for corporate or professional use and carries a warranty in the event of failure.
Other Differences between Xp/Xg & Xs would be that:
Digi-SSL™ Xg Certificates are only supplied in specific cases where multiple hosting specifications require flexible naming within the Digi-SSL™. This specialist configuration can include multiple Common Names within the same Certificate, wildcard facilities or a combination of these requirements.
