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

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(input));

// 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.
