Sanjay.C,
I researched and found information on the abstract class from which all
implementations of the MD5 hash algorithm inherit using C#
I obtained this code from one our new sites:
************************************************** **************************
*******************************************
using System;
using System.Security.Cryptography;
using System.Text;
class Example
{
// Hash an input string and return the hash as
// a 32 character hexadecimal string.
static string getMd5Hash(string input)
{
// Create a new instance of the MD5CryptoServiceProvider object.
MD5 md5Hasher = MD5.Create();
// Convert the input string to a byte array and compute the hash.
byte[] data =
md5Hasher.ComputeHash(Encoding.Default.GetBytes(in put));
// Create a new Stringbuilder to collect the bytes
// and create a string.
StringBuilder sBuilder = new StringBuilder();
// Loop through each byte of the hashed data
// and format each one as a hexadecimal string.
for (int i = 0; i < data.Length; i++)
{
sBuilder.Append(data[i].ToString("x2"));
}
// Return the hexadecimal string.
return sBuilder.ToString();
}
// Verify a hash against a string.
static bool verifyMd5Hash(string input, string hash)
{
// Hash the input.
string hashOfInput = getMd5Hash(input);
// Create a StringComparer an comare the hashes.
StringComparer comparer = StringComparer.OrdinalIgnoreCase;
if (0 == comparer.Compare(hashOfInput, hash))
{
return true;
}
else
{
return false;
}
}
static void Main()
{
string source = "Hello World!";
string hash = getMd5Hash(source);
Console.WriteLine("The MD5 hash of " + source + " is: " + hash +
".");
Console.WriteLine("Verifying the hash...");
if (verifyMd5Hash(source, hash))
{
Console.WriteLine("The hashes are the same.");
}
else
{
Console.WriteLine("The hashes are not same.");
}
}
}
// This code example produces the following output:
//
// The MD5 hash of Hello World! is: ed076287532e86365e841e92bfc50d8c.
// Verifying the hash...
// The hashes are the same.

This is very new

Hi all,
I need C# code for Implementing MD5 Algorithm.. Hope all would have
heard of MD5 Algorith... Does any one have the C# coding for that
Algorithm.. please Send... ITs URgent.....
Thanks In Advance to all.......................
With Regards,
Sanjay.C
