Objective Non-encrypted grab packets Packet capture after encryption Basic requirements and concepts AES algorithm AES Fundamentals and Algorithmic flow AES Algorithm Flow RSA algorithm

With the development of symmetric cipher, the DES data Encryption Standard algorithm, because of its small key length (56 bits), has not adapted to the requirements of today's distributed open Network for data encryption security, so 1997 NIST
