Class SSLFTPCipherSuite

java.lang.Object
  extended by com.enterprisedt.net.ftp.ssl.SSLFTPCipherSuite

public class SSLFTPCipherSuite
extends java.lang.Object

This class servers two purposes: It provides an interface to obtaining information about particular cipher-suites and it provides a set of available cipher-suites.

A cipher-suite is a set of algorithms that is used for various aspects of SSL security. For a client and a server to be able to communicate, they must be able to agree on a particular cipher-suite. Different types of servers recognize different cipher-suites, so it is usually up to the client make sure that it shares at least one cipher-suite with the server that it is trying to communicate securely with. By itself, this fact would imply that the client should simply enable all possible suites in order to increase the chances of overlap. However, this is not necessarily wise since some cipher-suites (esp. those which adhered to the (now defunct) US export restrictions are relatively easy to break, whereas some others are trusted as currently being virtually unbreakable.

A cipher-suite consists of a digital signature algorithm, a key-exchange algorithm, an encryption algorithm, and a digest algorithm.
