StandardConstants

AI-generated Key Takeaways

StandardConstants defines standard constants used in network security protocols, primarily for Server Name Indication (SNI) in SSL/TLS.
The main constant is SNI_HOST_NAME, representing the DNS hostname type in an SNI extension, enabling clients to specify the target server during the handshake.
This class inherits standard methods from java.lang.Object like equals, hashCode, toString, and thread management methods.
SNI_HOST_NAME has a constant value of 0x00 and is crucial for secure and efficient communication by ensuring the client connects to the intended server.

Constant Summary

int SNI_HOST_NAME The "host_name" type representing of a DNS hostname (see SNIHostName) in a Server Name Indication (SNI) extension.

Inherited Method Summary

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object obj) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait(long timeout, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long timeout) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.

Constants

public static final int SNI_HOST_NAME

The "host_name" type representing of a DNS hostname (see SNIHostName) in a Server Name Indication (SNI) extension.

The SNI extension is a feature that extends the SSL/TLS protocols to indicate what server name the client is attempting to connect to during handshaking. See section 3, "Server Name Indication", of TLS Extensions (RFC 6066).

The value of this constant is 0x00.
