Plaintext: 1100000000111100101010    

      Key, k: 11100100   

length of Initialization Vector (IV), l, 4 where l < (the length of plaintext above)/2 

          IV: 1100   



Put your text of size l to get the corresponding value of Fk(text) of size l.

   Your text: 11001010           
Function output: 


Final Output:
