Question: Use CrypTool and encrypt your name with 3-DES in the ECB mode under the following two encryption keys: K1 = 11 22 33 44 55

Use CrypTool and encrypt your name with 3-DES in the ECB mode under the following two encryption keys:

K1 = 11 22 33 44 55 66 77 88 AA BB CC DD EE FF FF FF

K2 = 11 22 33 44 55 66 77 88 11 22 33 44 55 66 77 88

Decrypt resulting ciphertexts using 1-DES cipher. Provide any intermediate results that you obtain.

One among the keys K1 and K2 enables fast decryption with the 1-DES cipher (a single application of 1-DES). Which one? Please explain your answer.
