Interface SnmpUsmPrivAlgorithm

All Superinterfaces:

SnmpUsmAlgorithm

All Known Implementing Classes:

SnmpUsmDesAlgorithm

public interface SnmpUsmPrivAlgorithm
extends SnmpUsmAlgorithm

Encryption algorithm interface. Every privacy algorithm must be compliant to this interface. When developing your own algorithm you have to implement this interface.

Since:

Java DMK 5.1

Method Summary

byte[]	decrypt(byte[] key, com.sun.management.internal.snmp.SnmpEncryptionPair pair) Decrypt some data using a key.
com.sun.management.internal.snmp.SnmpEncryptionPair	encrypt(byte[] key, byte[] data, int length) Encrypt some data using a key.
int	getDeltaSize() Gets the delta size.
int	getKeySize() The privacy algorithm key size.
