This interface defines the secure socket stream connection. A secure connection is established using <CODE>Connector.open</CODE> with the scheme "ssl" and the secure connection is established before <CODE>open</CODE> returns. If the secure connection cannot be established due to errors related to certificates a <CODE>CertificateException</CODE> is thrown. <P> A secure socket is accessed using a generic connection string with an explicit host and port number. The host may be specified as a fully qualified host name or IPv4 number. e.g. <code>ssl://host.com:79</code> defines a target socket on the <code>host.com</code> system at port <code>79</code>. <P>Note that RFC1900 recommends the use of names rather than IP numbers for best results in the event of IP number reassignment. </P> <P> A secure connection MUST be implemented by one or more of the following specifications: <UL> <LI>TLS Protocol Version 1.0 as specified in <A HREF="http://www.ietf.org/rfc/rfc2246.txt">RFC 2246</A>. </LI> <LI>SSL V3 as specified in <A HREF="http://home.netscape.com/eng/ssl3/draft302.txt"> The SSL Protocol Version 3.0</A> </LI> <LI>WAP(TM) TLS Profile and Tunneling Specification as specified in <A HREF="http://www.wapforum.com/what/technical.htm"> WAP-219-TLS-20010411-a</A> </LI> </UL> <H2> BNF Format for Connector.open() string </H2> <P> The URI must conform to the BNF syntax specified below.
