SSL Certificates

Secure Socket Layer (SSL) is a protocol developed by Netscape in 1996 which quickly became the method of choice for securing data transmissions across the Internet. SSL is an integral part of most Web browsers and Web servers and makes use of the public-and-private key encryption system developed by Rivest, Shamir, and Adleman.

In order to make an SSL connection, the SSL protocol requires that a server should have a digital certificate installed. A digital certificate is an electronic file that uniquely identifies individuals and servers. Digital certificates serve as a kind of digital passport or credential which authenticate the server prior to the SSL session being established.

Typically, digital certificates are signed by an independent and trusted third party to ensure their validity. The "signer" of a certificate is known as a Certification Authority (CA), such as Symantec, thawte and GeoTrust.

SSL is an acronym for Secure Sockets Layer, an encryption technology that creates an encrypted connection between your web server and your visitors' web browser. This encryption technology enables private information to be transmitted easily without facing problems such as data tampering, or message forgery. If you are sending vital data on a web site, such as credit card numbers or personal data, you need to secure it with a SSL encryption. There is always a possibility that the data you are transmitting may be seen by others, unless it is secured by an SSL certificate. Net4 offers various kinds of SSL certificates from Thawte, Geotrust and Symantec to its customers.
