This class
is a factory for socket and server socket factories. Although most
applications do not need to use this class directly, it is the
central class of the javax.net.ssl package. Most
applications use the default SSLSocketFactory and
SSLServerSocketFactory objects returned by the
static getdefault( ) methods of those classes.
Applications that want to perform SSL networking using a security
provider other than the default provider, or that want to customize
key management or trust management for the SSL connection should use
custom socket factories created from a custom
SSLContext. In Java 5.0, this class also includes
createSSLEngine( ) factory methods for creating
SSLEngine objects.Create an SSLContext by passing the name of the
desired secure socket protocol and, optionally, the desired provider
to getInstance( ). The default
"SunJSSE" provider supports
protocol strings "SSL",
"SSLv2",
"SSLv3",
"TLS", and
"TLSv1". Once you have created an
SSLContext object, call its init(
) method to supply the KeyManager,
trustManager, and SecureRandom
objects it requires. If any of the init( )
arguments is null, a default value will be used.
Finally, obtain a SSLSocketFactory and
SSLServerSocketFactory by calling
getSocketFactory(
) and getServerSocketFactory(
).public class SSLContext {
