That is the difference between the key lengths used once an SSL connection has been established in the browser. 256-bit security is indeed a bigger key however that does not necessarily mean it is more secure. Experts and research agrees that 128-bit is equally secure for the foreseeable future. The only reason 256-bit security is needed is if it’s specifically required by your industry or company policy.

All our certificates have the ability to use either bit-length, which one you use is a matter of server configuration, NOT certificate support.

If your hosting platform or company tells you that you can only use one certificate file, then you can combine your server certificate with the intermediate file.

You can use SSL to cover an internal domain if it is an officially registered domain (a publically available FQDN). If the internal domain is not a delegated and registered domain, the certificate will not be issued.

An intermediate certificate will be emailed to you along with your SSL certificate. You can also download the intermediate certificate from the vendor’s website, which is something that can be done if you didn’t receive the intermediate via email. This is also sometimes referred to as the “CA Bundle.” It is also important to note that some certificates have multiple intermediate certificates.

Below are the links that you can use to download your intermediate certificate from the vendor website:

An intermediate certificate is a file that helps the web browser identify who issued your SSL certificate. It is not required, but it is HIGHLY recommended that you install it along with your server SSL certificate in order to have full compatibility with all browsers and mobile devices.

Our SSL certificates can be valid from anywhere to 1-2 years, depending on the certificate you choose to purchase. Per the Certificate Authority/Browser (CA/B) Forum, the governing body of the SSL industry, EV certificates can only be issued for a maximum of 2 years. DV and OV certificates from Symantec, GeoTrust, Thawte, Comodo and RapidSSL can be issued for a maximum of 2 years.

Browser ubiquity or browser recognition basically means how many browsers recognize an SSL certificate and properly display the trust indicators. So, the higher the browser ubiquity of an SSL certificate, the more browsers that recognize and accept it.

An SSL certificate warranty covers any damages that you may incur as a result of a data breach or hack that was caused due to a flaw in the certificate. The warranties range in value, which means that the higher value certificates come with more extensive warranties.

Yes, the brands that we provide all have their roots included in modern devices and browsers. They all feature 99% or better compatibility, or browser ubiquity.

All of the Certificate Authorities (CAs) that we carry are leaders in the industry and trusted across the world. Symantec is the largest CA in the world, and their Norton Trust Seal is the most recognized symbol of trust across the web. Their name definitely adds the most value of any CA in the industry. Additionally, GeoTrust, Thawte, RapidSSL, and Comodo are all trusted and secure CAs.
