CAESAR CIPHER – ENCRYPTION/DECRYPTION

CAESAR CIPHER – ENCRYPTION/DECRYPTION

When you start your journey into Cryptography, one of the basic encryption techniques you will learn is the Caesar Cipher.

The cipher is almost a thousand years old and was used in the time of Roman dictator Julius Caesar who used this cipher to provide cryptic orders to his army. 

This simple mini project on Cybersecurity offers you the opportunity to work on and understand encryption and decryption using Caesar Cipher. The project follows the simple logic of a numeric cipher value that is used to shift the place values of respective alphabets of a certain text. 

For example: For a text, say VERZEO if we apply a cipher value (also known as a key) of 3, then the alphabets are shifted to the right of it by that many times. 

So VERZEO becomes, YHUCHR which is also known as the ciphertext. The same trick is applied to retrieve the normal text. 

You can create the Cipher using a Program across any programming language that can work on the encryption and decryption of the given text.
