There is a quiet, international battle underway, a battle that impacts every data consumer and producer. The important part of this battle are the cryptographers who work to protect users' national security and the privacy of users' personal information through increasingly strong methods of encryption. This paper developed a double encryption design using Very high speed integrated circuits Hardware Description Language (VHDL) and a Field Programmable Gate Arrays technology (FPGA) aimed to ensure privacy to the transmitted data over open networks. The presented paper is a type of modern encryption technique. It used a combination of transposition and substitution encryption techniques that help to generate complex cipher.
