SSL Certificates

SSL (Secure Sockets Layer) is a protocol developed by Netscape for ensuring secure transactions between web browsers and web servers. Many websites use the protocol to obtain confidential user information, such as credit card numbers. By convention, URLs that require an SSL connection start with https instead of http.

What pages should I secure using the SSL?
The web pages you would want to secure are generally those that require the entry of sensitive information, such as passwords, personal information, credit card numbers and other financial information, although some may want to secure an entire set of pages using SSL certificates.
Is there any alternative to SSL?
Secure HTTP is another protocol for transmitting data securely over the World Wide Web. SSL creates a secure connection between a client and a server, over which any amount of data can be sent securely, S-HTTP is designed to transmit individual messages securely.
Both protocols have been approved by the Internet Engineering Task Force (IETF) as a standard.
