General Info:

    The source codes are available in /src :

        The Encryption Algorithm is Part1.java
        The Decryption Algorithm is Part2.java
        The Key Generator is Part3.java

    The codes can be compiled by any java compiler and IDE

Inputs and Outputs:

The code only allows inputs in hexadecimal 128 bit format and prints outputs in a hexadecimal 128 bit format. it is expected for the input and output to be given/printed as the following:

Part1 (Encryption):

Input :
The Key : a 128 bit hexadecimal value
The Plain text : a 128 bit hexadecimal value

Example :
c0000000000000000000000000000000 00000000000000000000000000000000

Output :
The Cipher text : a 128 bit hexadecimal value

Example :
4bc3f883450c113c64ca42e1112a9e87

Part2 (Decryption):

Input : The Key : a 128 bit hexadecimal value The Cipher text : a 128 bit hexadecimal value

Example :
80000000000000000000000000000000 0edd33d3c621e546455bd8ba1418bec8

Output :
The Plain text : a 128 bit hexadecimal value

Example :
00000000000000000000000000000000

TODO : check if the input value is a 128 bit hex value (until then check the validity of the number manually)

The Key and Plain Text for all of the rounds is also being printed and can be seen (Part1)

TODO : printing the cipher text for each decryption round isnt implemented

Part3 (Key Gen) : this website assisted me in writing this algorithm

the input is given as :
p , g , a , b (instructions given in the link above)
and the output is printed as :
result seen by person A , result seen by person B , f Key
