************ WELCOME ***************
This is Irwin Yoon's program illustrating 
IDEA (International Data Encryption Algorithm)
************************************


IDEA takes in a 128-bit key. 
User will enter 16 alphanumeric characters
These 16 alphanumeric characters will be 
converted to a 128-bit key. 
  (16 char * 8bits = 128 bits)


Please enter 16 alphanumberic characters, then press enter
1234567890123456

Thank you.
Original Key in text: 1234567890123456
	Original Key 1st 32bits: 0x31323334
	Original Key 2nd 32bits: 0x35363738
	Original Key 3rd 32bits: 0x39303132
	Original Key 4th 32bits: 0x33343536


MAIN MENU
=========
Press 1 to print all Encryption/decryption keys 
Press 2 to encrypt plaintext with intermediate results
Press 3 to decipher ciphertext with intermediate results
Press 4 to encrypt, then decrypt (No intermediate results shown)
Press 5 to quit 

Your choice:    2

************ ENCRYPTION OF PLAINTEXT **********

Data block size is 8 bits.   
Therefore, please enter 8, 16, 24, 32 characters
