The SecureCacheResponse Class in Java represents a cache response originally retrieved through secure means.
Syntax: Class Declaration
public abstract class SecureCacheResponse extends CacheResponse
The constructor for this class is as follows
SecureCacheResponse()
Now, the methods of this class are as follows:
Method | Description |
---|---|
getCipherSuite() | This method is used to return the cipher suite in use on the original connection that retrieved the network resource. |
getLocalCertificateChain() | This method is used to return the certificate chain that was sent to the server during handshaking of the original connection that retrieved the network resource. |
getLocalPrincipal() | This method is used to return the principal that was sent to the server during handshaking in the original connection that retrieved the network resource. |
getPeerPrincipal() | This method is used to return the server’s principal which was established as part of defining the session during the original connection that retrieved the network resource. |
getServerCertificateChain() | This method is used to return the server’s certificate chain, which was established as part of defining the session in the original connection that retrieved the network resource, from the cache. |
Example:
Java
// Java program to demonstrate SecureCacheResponse class // Implementation and its methods // Importing IOException and InputStream classes from // java.io package import java.io.IOException;
import java.io.InputStream;
// Importing java.net package for network linking import java.net.*;
// Importing classes from java.security package to provide // security framework to classes and interfaces import java.security.Principal;
import java.security.cert.Certificate;
// Importing Map and List classes from java.util package import java.util.List;
import java.util.Map;
// Importing class when peer not authenticated import javax.net.ssl.SSLPeerUnverifiedException;
// Main class // JavaSecureCacheResponse public class GFG {
// Method 1
// Main driver method
public static void main(String args[]) throws Exception
{
// Creating an final object of Principal class
final Principal gfgPrincipal = new Principal() {
// Method 2
public String getName()
{
// As it is simply retrieving names
return null ;
}
};
// Creating an object of this class
// (SecureCacheResponse)
final SecureCacheResponse secureCacheResponse
= new SecureCacheResponse() {
// Method 3
// To get the name of the cipher suite
public String getCipherSuite()
{
// Returning the name of the cipher
// suite negotiated during this
// handshake This message will be
// displayed on console
return "Connection established" ;
}
// Method 4
// getLocalCertificateChain() method
public List<Certificate>
getLocalCertificateChain()
{
return null ;
}
// Method 5
public List<Certificate>
getServerCertificateChain()
throws SSLPeerUnverifiedException
{
// Returning peer certificate chain
// associated with the ssl socket
return null ;
}
// Method 6
// getPeerPrincipal() method
public Principal getPeerPrincipal()
throws SSLPeerUnverifiedException
{
return gfgPrincipal;
}
// Method 7
// getLocalPrincipal() method
public Principal getLocalPrincipal()
{
return gfgPrincipal;
}
// Method 8
public Map<String, List<String> >
getHeaders() throws IOException
{
return null ;
}
// Method 9
public InputStream getBody()
throws IOException
{
return null ;
}
};
// Print and display commands which are returning
// information
// 1. The cipher suite in use on the original
// connection
System.out.println(
"getCipherSuite() method returns: "
+ secureCacheResponse.getCipherSuite());
// 2. The server's principal which was recognized
// as a part of determining the session.
System.out.println(
"getPeerPrincipal() method returns: "
+ secureCacheResponse.getPeerPrincipal());
// 3. An immutable List of Certificate representing
// the certificate chain that was sent to the
// server.
// 4. null, as no certificate chain was sent
System.out.println(
"getLocalCertificateChain() returns: "
+ secureCacheResponse
.getLocalCertificateChain());
// 5. Principal that was sent to the server
// during the handshaking of the original connection
System.out.println(
"getLocalPrincipal() method returns: "
+ secureCacheResponse.getLocalPrincipal());
}
} |
Output
getCipherSuite() method returns: Connection established getPeerPrincipal() method returns: GFG$1@34a245ab getLocalCertificateChain() returns: null getLocalPrincipal() method returns: GFG$1@34a245ab
