Hi Antony
As I understand from you post the answers to your questions are below.
You have downloaded the VHDl files for the Encryption algorithm .You will find that there will be a top level file that binds all the modules in the design. In VHDL we have top level ENTITY that has all the bus designed entities attached to it. All you need is to make a project. Include all VHDL files and locate the TOP LEVEL entitiy file and use this top level for simulation purpose.
Answer to second question is you will have to interface a interface between the memory and the DES/AES algo block that you have downloaded from Open Cores.
So it will take data from the flash---> Encrypt it with encryption b-----> store it in another memory. For this snother memory you will again have to design an interface block.
Hope this helps
