Comment on Attempted Forced Foursquare by random101naru

In regard to that “masking” thing,
would it happen that the plaintext was “DEcrypted” instead of “ENcrypted”?
Like “Decoding” the plaintext, and then encoding that cipher text to make the present ciphertext.
I think that would be a good idea to take into consideration.
Hope this helps & good luck with it!
