Different SSL Certificates
Are you looking to buy SSL
certificates? This article contains information on
popular providers of Secure Socket Layer (SSL)
certificates (such as verisign and thawte), price
ranges for SSL certificates, and tips on choosing
which SSL certificate to buy.
The CA, or certificate authority, is the entity that issues
The three basic types of SSL certificates are listed below:
The CA will confirm domain control by sending an email to the
administrator listed with the registrar for the domain. If the authorized
administrator does not reply, a second email will be sent to an email
address at the domain such as info@ or support@. (You may select a secondary
email address during the enrollment process.) In addition to validation by
email, you will be asked to provide a telephone number where you can be
reached immediately after submitting your enrollment. If everything checks
out, the SSL certificate is issued.
Organization Validated certificates are issued after the CA has verified
domain control and conducted background checks into the company that owns
Extended validation certificates offer the highest level of trust to the
end-user and turn the address bar green during secure sessions. EV
certificates are issued according the guidelines set out by the CA/Browser
Different SSL certificates protect from one domain to multiple domains.
The single domain SSL certificate protects one domain. It will protect
example.com and www.example.com. Validation is through an email and can be processed very quickly. The
person who owns the domain is validated that the applicant owns it.
Single Domain Wildcard
A Wildcard SSL certificate provides the same encryption and
authentication features as other SSL certificates. However, a Wildcard
certificate can also be applied to unlimited subdomains of a site. Some
sites utilize subdomains like blog.mysite.com. A Wildcard SSL certificate
supports the root domain (mysite.com) as well as its subdomains.
A multidomain certificate protect many domains with one certificate.
