In this Wireless Data Encryption and Decryption System project, we are using PC Keyboard to enter the required text information. The microcontroller accepts this data, encrypts it and then sends it to remote place using the proper code given by the user. The information will be shown on the 16*2 LCD.

The same information will be transmitted to remote place using RF Transmitter Module working on 435 Mhz.

The information is then received at another end with the help of RF Receiver Module. The data is then given to microcontroller which will be decrypted using the same code and finally shown on the 16*2 LCD.
