SSL: What does it mean?
Short for Secure Sockets Layer, a protocol
developed by Netscape for transmitting private documents via the Internet.
SSL works by using a public key to encrypt data that's transferred over the
SSL connection. Both Netscape Navigator and Internet Explorer support SSL,
and many Web sites use the protocol to obtain confidential user information,
such as credit card numbers. By convention, Web pages that require an SSL
connection start with https: instead of http:.
Another protocol for transmitting data securely over the World Wide Web is
Secure HTTP (S-HTTP). Whereas 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. SSL and S-HTTP,
therefore, can be seen as complementary rather than competing technologies.
Both protocols have been approved by the Internet Engineering Task Force (IETF)
as a standard.
