PasswordGenerator

In Generator class you will find PasswordGenerator() method, by using this you can generate random passwords with uppercase/lowercase letters, also numbers.

• PasswordGenerator() method uses RNGCryptoServiceProvider class.

using (var rng = new RNGCryptoServiceProvider())
{
 var data = new byte[4];
 rng.GetBytes(data);
 var seed = BitConverter.ToInt32(data, 0);
 var rnd = new Random(seed);

 string password = string.Empty;

for (int i = 0; i < length; i++)
{
 if (rnd.Next(1, 4) == 1)
     password += (char)rnd.Next(48, 57);
 else if (rnd.Next(1, 4) == 2)
     password += (char)rnd.Next(65, 90);
 else
     password += (char)rnd.Next(97, 122);
}
 return password;
              

Using UserProgram class you can execute the program, simply write the required length of password you want to generate, instead of 10.

Console.WriteLine(Generator.PasswordGenerator(10));
