如何用c語言寫希爾密碼？

//希爾算法加密解密\ x0d \ # include \ x0d \ # include \ x0d \ # include \ x0d \ # include//nDime是所有變量，可逆矩陣的維數\ x0d \ int nDime\ x0d \ int index = 0；// MAXN是明文的最大長度\ x0d \ const int MAXN = 256//矩陣乘法，其中a是列為1的矩陣\ x0d \ void乘法矩陣(int a []，int b [] [10]，int * text) \ x0d \ {\ x0d \ inti，j，t；for(I = 0；I = size)\ x0d \ sum % = size；\ x0d \ temp 1[diff]* = m[行][列]；\ x0d \ temp 2[sum]* = m[行][列]；\ x0d \ } \ x0d \ } \ x0d \ t = 0；\ x0d \ for(row = 0；排
