SHA1 HEX DIGEST

C# code using the API to produce a message digest from a password

using System;
using System.Text;
using System.Security.Cryptography;

public class TestSHA1
{
 public static void Main()
 {
  string message = "abc";
  SHA1 sha = new SHA1Managed();
  ASCIIEncoding ae = new ASCIIEncoding();
  byte[] data = ae.GetBytes(message);
  byte[] digest = sha.ComputeHash(data);
  Console.WriteLine(GetAsString(digest));
  Console.ReadLine();
 }
 public static string GetAsString(byte[] bytes)
 {
  StringBuilder s = new StringBuilder();
  int length = bytes.Length;
  for (int n=0; n < length; n++)
  {
   s.Append((int) bytes[n]);
   if (n != length - 1) { s.Append(' '); }
  }
  return s.ToString();
 }
}


The C# code produces the following message digest for the string "abc"

169 153 62 54 71 6 129 106 186 62 37 113 120 80 194 108 156 208 216 157


C# code to convert to hexadecimal string

public static string GetAsHexaDecimal(byte[] bytes)
{
 StringBuilder s = new StringBuilder();
 int length = bytes.Length;
 for (int n=0; n < length; n++)
 {
  s.Append(String.Format("{0,2:x}", bytes[n]).Replace(" ", "0"));
 }
 return s.ToString();
}
