An SSL certificate is a digital certificate that authenticates the identity of a Web site and encrypts information sent to the server using Secure Sockets Layer (SSL) technology. Encryption is the process of scrambling data into an undecipherable format that can only be returned to a readable format with the proper decryption key.

A certificate serves as an electronic "passport" that establishes an online entity’s credentials when doing business on the Web. When an Internet user attempts to send confidential information to a Web server, the user’s browser accesses the server’s digital certificate and establishes a secure connection.

An SSL certificate contains the following information:

• The certificate holder’s name
• The certificate’s serial number and expiration date
• A copy of the certificate holder’s public key
• The digital signature of the certificate-issuing authority

You will absolutely need a SSL Certificate if your website is gathering sensitive information such as Credit Cards Numbers, Social Security Numbers, Dates of Birth, Stock, Financial Data,  or any other sensitive information.
