Hi,

You may use a serial communication protocol (SPI or others) to provide the Key and plain text data and then retrieve ciphered data by the same mean. typically you will need only 4 pins.

Yours.
 

can i get any documentation on SPI from anywhere so that i can get more information abt it like procedure and working
