Organization Validated (OV) verification requires checking your business registration. If the Certificate Authority (CA) can verify this information using online government databases, no additional documents will be required. However, if the online filings are not available or inaccurate or not up to date, the CA may request additional official government registration documents, which vary on a case-by-case basis. A Dun & Bradstreet listing can usually satisfy most of the requirements for an OV certificate.

You do not need to provide any documentation in order to purchase a Domain Validated (DV) certificate. All you will need to do is confirm that you own the domain you wish to cover, either through a simple email or file-based authentication.

You can switch your method of Domain Control validation from file-based to email-based for any SSL product that we provide. You can switch from email-based to file-based only for Comodo products.

If you are unsure what your Control Panel/Server OS is, we recommend that you ask your web hosting provider or your IT department.

If you’re in a pinch and need your certificate fast, feel free to contact your SSL provider with the exact order you need expedited. They have connections with the Certificate Authorities (CAs) directly and can help make sure your urgent order is treated with top priority.

Your private key should always remain private. The only person that should see your private key is your hosting company, if they ask for it. However, do not delete your private key, as it is required for your certificate to work.

A Multi-Domain Wildcard SSL certificate can secure multiple domains and all of their associated subdomains. Basically, this certificate combines multiple wildcard domains into one certificate.

UC stands for Unified Communications and is a newer type of SSL certificate that is designed and primarily used for securing Microsoft Exchange 2007 and Microsoft Office Communications Server 2007 products. The main difference between a UCC SSL and a standard Multi-Domain certificate is that a UCC can secure both internal network names and external domain names as well.

This largely depends on the type of Multi-Domain SSL certificate that you purchase. Comodo Multi-Domain certificates can cover up to 100 additional domains. Symantec and Thawte certificates can cover up to 25 additional domains. GeoTrust Multi-Domain certificates can cover anywhere between 25-100 additional domains, depending on the certificate.

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.
