Solution 1

Binary, octal and hex are all the same in this context - you just need to convert the string to bytes:
string s = "Hello!";
byte[] bytes = System.Text.Encoding.ASCII.GetBytes(s);

1st write this function on your page:

public static string ConvertToBin(string asciiString)
       StringBuilder sb = new StringBuilder();
       foreach (string letter in asciiString.Select(c => Convert.ToString(c, 8)))
       return sb.ToString().Substring(0,5);
then write this coding where u want to show ur encrypt key like textbox means write like this it show 5 digit encrypt key:

TextBox1.Text = ConvertToBin(a);
TextBox2.Text = ConvertToBin(content.Substring(content.Length - 5, 5)); RSACryptoServiceProvider rsa = new RSACryptoServiceProvider();
TextBox3.Text = ConvertToBin(rsa.ToXmlString(true).Substring(15, 5));
TextBox4.Text = ConvertToBin(rsa.ToXmlString(true).Substring(15, 5));
TextBox5.Text = ConvertToBin(rsa.ToXmlString(true).Substring(22, 5));
TextBox6.Text = content;
