I tried to test Shiva but dosent not encrypt my USB E:/ drive
In this function:
//creates random password for encryption
public string CreateRandomString(int length, String str)
{
string valid = str;
StringBuilder res = new StringBuilder();
Random rnd = new Random();
while (0 < length--) {
res.Append(valid[rnd.Next(valid.Length)]);
}
return res.ToString();
}
Your are using System.Random()
to generate random position index in the str
string. The problem is that the default seed is generated by Environment.TickCount
(https://referencesource.microsoft.com/#mscorlib/system/random.cs) and it can be predictable as it's said in this article: https://utkusen.com/blog/destroying-the-encryption-of-hidden-tear-ransomware.html.
Use RNGCryptoServiceProvider
to generate the private key (https://dotnetcodr.com/2016/10/05/generate-truly-random-cryptographic-keys-using-a-random-number-generator-in-net/).
