This packets implements one of the most basic method of encryption called Caesar cipher encryption along with decryption in C++
This packet implements the simplest encryption algorithm i.e Caesar Cipher algorithm in C++
this packet includes the following files -
1- main.cpp : this c++ code implements the algorithm for encryption and decryption.
2- input.txt : this text file contains the plain text which needs to be encrypted, our program reads plain text from this file.
3- encryption.txt : the encrypted text is written back to this file after encryption.
4- outputtext.txt : after decryption plain text is written back to this file.
1- write plain text in input.txt file.
2- run main.cpp. select encryption to encrypt plain text and store encrypted data in encryption.txt file.
3- enter key when prompted and remember this key because the same key will be used during decryption.
4- for decryption choose the option of decryption and enter the key which was used during encryption.
5- plain text will be stored in outputtext.txt file.
