Differences in SSL certificate validation
There are three kinds of validation that SSL certificate providers perform. Some certificates require more involved validation, others require simple domain validation: if you can send an email from the domain, they consider you the owner.
For example, a GeoTrust True BusinessID with EV certificate requires "High-assurance extended validation," which includes providing very detailed business and financial information, corporate documents, DBA, etc. A GeoTrust True BusinessID certificate requires "Strong organization/business identity" validation, which requires somewhat less detailed business information.
The higher the warranty value provided, the more rigorous the validation will be. For most sites the domain-validated PositiveSSL certificate will be sufficient. But e-commerce sites or sites that store a lot of personal information might benefit from a higher level certificate. All certificates provide "https" web addresses and display a "padlock" or other security icon in the browser.
Additionally, the less expensive certificates provide a static "seal" icon while the more expensive certificates provide a dynamic seal with date/time stamp, etc. The GeoTrust True BusinessID with EV turns the browser address bar green for a visible indication that the web page is secure.
If you already have an SSL certificate you can transfer it to a DiscountASP.NET site
If you transfer a certificate to a DiscountASP.NET site, we recommend that you generate a new CSR from our Control Panel and ask your SSL provider to re-key the certificate. If the certificate is not re-keyed it is not secure, since the old host may retain the key pair information that decrypts your SSL certificate.
