Typically, the public key is widely distributed. The private key, however, is kept
secret, so that the message can only be decrypted by someone in possession of the
private key.
Using this method of encryption, both the request for a document and the
document itself are encrypted to ensure that a text message can be read only by
the intended recipient.
Netscape's SSL Encryption
Another effective encryption scheme is called Secure Socket Layer (SSL). SSL is
a technology developed by Netscape that encrypts transactions that use the web-
based HTTP, NNTP, and FTP protocols. SSL allows server authentication
(verifying the server's identity to the client), encryption of data in transit, and
client authentication (verifying the client's identity to the server).
The following table lists security options supported by the three main web server
vendors.
