[238]Sets up an SSL socket to securely communicate with a Web server, using the HTTPS protocol
By Anonymous on 2003/04/25 14:43:42 Rate
//The following code sets up an SSL socket to securely communicate with a Web server, using the HTTPS protocol:
import javax.net.ssl.*;
import java.io.*;
// Get a SocketFactory object for creating SSL sockets
SSLSocketFactory factory = ( SSLSocketFactory ) SSLSocketFactory.getDefault ( ) ;
// Create a secure socket connected to the HTTPS port ( port 443 ) of a server
SSLSocket sslsock = ( SSLSocket ) factory.createSocket ( hostname, 443 ) ;
// Get the certificate presented by the web server. This may throw an
// exception if the server didn't supply a certificate. Look at the
// issuer of the certificate and decide if it is trusted.
SSLSession session = sslsock.getSession ( ) ;
X509Certificate cert = ( X509Certificate ) session.getPeerCertificates ( ) [ 0 ] ;
String issuer = cert.getIssuerDN ( ) .getName ( ) ;
// Assuming we trust the certificate, we now use the socket just like a normal
// java.net.Socket object. So send a HTTP request and read the response
PrintWriter out = new PrintWriter ( sslsock.getOutputStream ( ) ) ;
out.print ( "GET " + args [ 1 ] + " HTTP/1.0\r\n\r\n" ) ;
out.flush ( ) ;
// Next, read the server's response and print it to the console.
BufferedReader in =
new BufferedReader ( new InputStreamReader ( sslsock.getInputStream ( ) ) ) ;
String line;
while ( ( line = in.readLine ( ) ) != null ) System.out.println ( line ) ;
// Finally, close the socket.
sslsock.close ( ) ;
//checkValidity
