Introduction to SSL - Archive of obsolete content
ssl has been universally accepted on the world wide web for authenticated and encrypted communication between clients and servers.
...it uses tcp/ip on behalf of the higher-level protocols, and in the process allows an ssl-enabled server to authenticate itself to an ssl-enabled client, allows the client to authenticate itself to the server, and allows both machines to establish an encrypted connection.
... an encrypted ssl connection requires all information sent between a client and a server to be encrypted by the sending software and decrypted by the receiving software, thus providing a high degree of confidentiality.
