2.3.1 SSL/TLS (Secure Sockets Layer / Transport Layer Security)
SSL (Secure Sockets Layer) and TLS
(Transport Layer Security) are related secure communication technologies
that make use of public key encryption and key exchange, and X.509 certificates,
discussed in more detail in Chapter 4.
To use SSL and TLS, you need to generate
a digital certificate (some platforms offer tools to do this) or obtain
one from a certificate authority. Again, see Chapter 4 for more information.
 SSL/TLS
SSL and TLS use public key encryption, key exchange, and X.509 certificates for communication privacy and user/site identification.
|
In terms of OSI layers, SSL and TLS
sit above TCP/IP, but below application protocols such as HTTP or IMAP.
