Is there anyway i can retrieve the sbox information from the javax.crypto package? I come across this site that show the sboxes of des alogrithm. http://www.gymnase-yverdon.vd.ch/branches/mathematique/cryptographie/textes/s_boxes.htm But i suspect different developers have different implementation on the sbox in another word, it does not mean everyone implement des will use similar sbox value. Greatly appreciate if anyone can help me with the sbox question.
If they use different SBoxes, then it isn't DES.
