Class ServerHello

Implemented Interfaces:
Constructed, Handshake.Body
Known Direct Subclasses:
ServerHelloBuilder

public class ServerHello
extends Object
implements Handshake.Body

The server hello message.
struct
{
ProtocolVersion server_version;
Random random;
SessionID session_id;
CipherSuite cipher_suite;
CompressionMethod compression_method;
Extensions server_hello_extension_list<0..2^16-1>
} ServerHello;

Server hello messages may contain extra data after the compression_method field, which are interpreted as extensions to the basic handshake.

Constructor Details

ServerHello

public ServerHello(ByteBuffer buffer)

Method Details

cipherSuite

public CipherSuite cipherSuite()
Returns the server's chosen cipher suite. The returned cipher suite will be "resolved" to this structure's version.
Returns:
The server's chosen cipher suite.

compressionMethod

public CompressionMethod compressionMethod()
Returns the server's chosen compression method.
Returns:
The chosen compression method.

extensions

public ExtensionList extensions()

extensionsLength

public int extensionsLength()

length

public int length()
Returns the total length, in bytes, of this structure.
Specified by:
length in interface Handshake.Body
length in interface Constructed
Returns:
The length of this structure.

random

public Random random()
Returns the server's random value. This method returns a lightwieght wrapper around the existing bytes; modifications to the underlying buffer will modify the returned object, and vice-versa.
Returns:
The server's random value.

sessionId

public byte[] sessionId()
Returns the session ID. This method returns a new byte array with the session ID bytes.
Returns:
The session ID.

toString

public String toString()
Overrides:
toString in interface Object

toString

public String toString(String prefix)
Returns a printable representation of this structure, with the given prefix prepended to each line.
Specified by:
toString in interface Handshake.Body
toString in interface Constructed
Parameters:
prefix - The prefix to prepend to each line of the output. This value may be null.
Returns:
A printable representation of this structure.

version

public ProtocolVersion version()
Returns the server's protocol version. This will read two bytes from the beginning of the underlying buffer, and return an instance of the appropriate ProtocolVersion; if the version read is a supported version, this method returns a static constant instance.
Returns:
The server's protocol version.
