README for AES128
*****************
Repository containing C++ and Verilog to implement AES128 for final year project.

C++ = C++ program to implement AES.

C_Microblaze_Tests = C code to test crypto modes through UART to Microblaze processor.

RTL_TB = Some verilog testbench files created during process of writing working Verilog.

RTL = Verilog to implement AES128-ECB & AES128-CBC:

	AES128-CBC Hierarchy:
	Encryption:

				-> sub_bytes
				-> shift_rows
				-> mix_columns
				-> add_round_key
			-> encrypt_final_round
