AES algorithm implementation in VC++
-
Hi all, I got a AES impelmentation code in VC++ and have some doubts, which I cannot sort out. Will you plssssssssss let me know if u are familiar with both the AES algorithm and VC++. So that I can forward my doubts along with the programme. Thx... Vendy

hi,, oh ok. There is an implementation of the AES algorithm in the below link. If u download it.. http://www.thecodeproject.com/cpp/aes.asp in Table.h (1.) Why have they used s boxes in ‘int’s? why not const int CRijndael::SBox[256] rather than ---const char CRijndael::SBox[256] and replace the negative values with positive? (2.) What does const int CRijndael::sm_T1[256] …. const int CRijndael::sm_T8[256] tables correspond to? (3.) and const int CRijndael::sm_U1[256]…const int CRijndael::sm_U4[256] tables correspond to (4.) also const int CRijndael::sm_shifts[3][4][2] tables correspond to? tnx
