Abstract: A network device includes a hardware pipeline to process a network packet to be encrypted. A portion of the hardware pipeline retrieves information from the network packet and generates a command based on the information. A block cipher circuit is coupled inline within the hardware pipeline. The hardware pipeline includes hardware engines coupled between the portion of the hardware pipeline and the block cipher circuit. The hardware engines parse and execute the command to determine a set of inputs and input the set of inputs and portions of the network packet to the block cipher circuit. The block cipher circuit encrypts a payload data of the network packet based on the set of inputs.
