Where, when does exactly the DES encryption / decryption key (64 octets) take part during the encryption /decryption process, because aparently both processes are based only in the initialization vector ? As you might know, according the RFC3414, from the DES localized key of 16 octets, the first 8 are used as DES encryption / decryption key (this is the only mention of this key in the document); and the final 8 are used as pre - initialization vector (pre IV) . The final initialization vector (8 octets) is obtained from operations made in the pre IV using the snmpEngineBoots of 4 octets and an arbitrary 4 octets value initialized at boot time. Please someone can help me explaining when is exactly the DES key used during the encryption and decryption of the messages? ------------------------------------------------------------------------------ Rapidly troubleshoot problems before they affect your business.
