Question on 3DES algorithm
Dear Wizards, according to this article: https://en.wikipedia.org/wiki/Triple_DES, the 3 DES algorithm is
ciphertext = EK3(DK2(EK1(plaintext)))
Why don't they just use like
ciphertext = EK3(EK2(EK1(plaintext)))
What are the differences in terms of security between DK2 and EK2 here? Many thanks!

Hi, okay so it is EDE instead of EEE just for backward compatible with DES?
If so, I can say 3DES is DES in case 3 Keys are same; but if 3 key are different, what are the points to use EDE, not EEE ?
Can anyone analyze the difficulty of cracking 3DES?
