JavaScript Encryption Program

• Caesar Cipher

Design (Back-End)

Classes

ConversionInstance

Stores some information of the current conversion

Properties

• id
• input
• conversionType
• output

Methods

• log
  • Logs the instance into array for previous actions

Encryption/Decryption Methods

Have objects for the different kinds of encryptions/decryptions ex) Enigma or CaesarShift Refer to Encryption Methods Implementation

Properties

• toEncrypt
  • true if user wants encryption, false otherwise
• Appropriate values needed for performing the conversion
  • Grabbed from the user input
  • Variable depending on the kind of conversion

Methods

• setProperties
  • Sets the properties of the conversion that is going to happen
  • Pulls values from user input fields
• encrypt
  • Takes ConversionInstance
  • Manipulates
• decrypt

Log

Stores previous conversions

Properties

• previousConversions

Methods

• getConversion
  • Fills input fields of previous conversion

Functions

Runner function (onClick)

• Creates a new Conversion object
• Checks whether encryption or decryption
• Switch statements to find out which encryption/decryption needs to be done
• Performs conversion
  • ex) If the user wanted an Enigma encryption:
    1. Enigma.setProperties();
    2. ConversionInstance.setOutput( Enigma.encrypt() );
• Stores object conversion through ConversionInstance.log();
• Program LMAO
