示例1: Decrypt

static void Decrypt(string input, GeneralMatrix key, GeneralMatrix invKey, Dictionary<char, int> hillDict, StringBuilder decText)
{
string pt = "";

for (int i = 0; i < line.Length; i += 3)
{
//3 at a time
double[] temp = new double[3];
temp[0] = Convert.ToInt32(line[i]);
temp[1] = Convert.ToInt32(line[i + 1]);
temp[2] = Convert.ToInt32(line[i + 2]);
//new 3x1 matrix
GeneralMatrix ctMat = new GeneralMatrix(new double[] { temp[0], temp[1], temp[2] }, 3);
//multiply by inverse
GeneralMatrix ptMat = inverse.Multiply(ctMat);
//mod 31 the result
