Digital signature

I'll see. Wikipedia This algorithm. Entered the staurus when he created the hesch for the text. M

  string M = "baaqab";
  var y = BigInteger.ModPow(g, x, p);
  var hM = CalculateMD5Hash(M);
  var r = BigInteger.ModPow(g, k, p);

♪ hM We're getting a line. 8A79B2FA38507C93B87022C065DEA270♪ Next in calculation s We're taking it away. m-xr♪ It is clear that all variables in the article are computed, and they can take a different number from number 3) But I have a hangover. There's half the numbers, half the text. I don't think I'm using the Hessing function for the M line. Who can tell?

Your implementation CalculateMD5Hash Something's converting the MD5 numerical value into a line. You probably have a code like:

public string CalculateMD5Hash(string input)
{
    // step 1, calculate MD5 hash from input
    MD5 md5 = System.Security.Cryptography.MD5.Create();
    byte[] inputBytes = System.Text.Encoding.ASCII.GetBytes(input);
    byte[] hash = md5.ComputeHash(inputBytes);
// step 2, convert byte array to hex string
StringBuilder sb = new StringBuilder();
for (int i = 0; i < hash.Length; i++)
{
    sb.Append(hash[i].ToString("X2"));
}
return sb.ToString();

}

Remove the transformation from it to line, leave only the heshing itself:

public BigInteger CalculateMD5Hash(string input)

{

MD5 md5 = System.Security.Cryptography.MD5.Create();

byte[] inputBytes = System.Text.Encoding.ASCII.GetBytes(input);

byte[] hash = md5.ComputeHash(inputBytes);

// добавить байт в конце чтобы получить гарантированно положительное значение
return new BigInteger(hash.Concat(new byte[] { 0 }).ToArray());

}

and work with the Hash as a lot.
