Caesar Cipher

Java application that implements a caesar cipher which is a type of substitution in which each letter is shifted a certain number of places known as a key (1-9), down the alphabet(A-Z).

Description

Caesar Cipher is a Java command line App which shifts letters a certain number of places known as Keys down the alphabets. For example the article "THE" with a key of 3 reads QEB. Each letter is moved 3 places backwards the Alphabets

Setup/Installation Requirements

• Make sure you have stable internet connection- Wifi or Cellular. Connect using your Mobile phone or Computer.
• To access the application, form the repository by clicking the form button. Go ahead to clone it to have it on your local repository.
• use git clone command followed by the link:
• After succesfully cloning, open the application using Intellij already installed in your computer.

Behavior Driven Development(BDD)

The user is able to;

• Run the application using

• Input the Characters to encode ie THE

• Key in the key ie 3

• Read the output Provided.

• (It also allows Testing the output before actual running of the App)

Running the Tests

Create a test class for running tests in the application.

This is a sample test that tests for character encryption moved three positions backward from its original position.

@Test public void encryptedCharacter_returnsCharMinusThreePositions_THE() { encryptedCharacter encryptedCharacter = new encryptedCharacter(); String expected = "QEB"; assertEquals(expected, encryptedCharacter.encryptedCharacter("THE", 3));

}
