Newbie here, have a question here, screenshot attached where by plaintext is applied to a block cipher using sboxes and permutation network. The specifications are in the picture.
what I am stuck on is as follows;
1) 7049c and 30f75 do these need to be converted into binary first and then applied to the system?
2) For the SBOX mapping do these need to be turned into binary first or how they turned into the table as outlined in the link below; http://en.wikipedia.org/wiki/S-box
