  com.rsa.ace.techservice.cipher.AgentCipherProviderFactoryImpl

public class AgentCipherProviderFactoryImpl
extends java.lang.Object

This implements the agent cipher provider factory. This creates AgentCipherProvider objects based on either a cipher suite provided or by looking at an agent buffer.

Method Summary

static AgentCipherProvider	getCipherProvider(byte[] agentBuffer, int headerSize, byte[] keyData) Cipher provider factory interface for existing packets.
static AgentCipherProvider	getCipherProvider(byte cipherSuite, byte[] keyData) Cipher provider factory interface for new packet construction.

Method Detail

getCipherProvider

public static AgentCipherProvider getCipherProvider(byte cipherSuite,
                                                    byte[] keyData)
                                             throws AgentCipherException

Cipher provider factory interface for new packet construction.

Parameters:

cipherSuite - The CipherSuite to be used for the packet.

keyData - The key to be used in the construction of the cipher provider.

Returns:

An Agent Cipher Provider.

Throws:

AgentCipherException - For unknown or unsupported cipher-suites.

getCipherProvider

public static AgentCipherProvider getCipherProvider(byte[] agentBuffer,
                                                    int headerSize,
                                                    byte[] keyData)
                                             throws AgentCipherException

Cipher provider factory interface for existing packets. For existing packets, the first byte in the header contains the cipher suite.

Parameters:

agentBuffer - The packet buffer. This is a complete agent packet including the cipher suite.

headerSize - This is the size of the cleartext, unencrypted header.

keyData - The key to be used in the construction of the cipher provider.

Returns:

An Agent Cipher Provider.

Throws:

AgentCipherException - For unknown or unsupported cipher-suites.
