java.lang.Object

org.snmp4j.security.PrivacyGeneric

org.snmp4j.security.PrivAES

org.snmp4j.security.nonstandard.PrivAESWith3DESKeyExtension

org.snmp4j.security.nonstandard.PrivAES256With3DESKeyExtension

All Implemented Interfaces:

Serializable, NonStandardSecurityProtocol, PrivacyProtocol, SecurityProtocol

public class PrivAES256With3DESKeyExtension
extends PrivAESWith3DESKeyExtension
implements NonStandardSecurityProtocol

This class is provided for interoperability with some broken AES 256bit implementations of major network device manufactures which use a key extension algorithm that was specified for Priv3DES but was never specified for AES 192 and 256 bit.

Note: DO NOT USE THIS CLASS IF YOU WANT TO COMPLY WITH draft-blumenthal-aes-usm-04.txt!
