Here a quick example how to create from an string an md5 hash in c# and output it as string. The only difficult is to convert from string to byte array and back again. So i have to method, one accept the byte array direct and returns a byte array, the second method handles the convert from string to byte array and back again.
using System.Security.Cryptography;
public static string GetMD5(string text)
{
if (text == null)
{
return string.Empty;
}
byte[] message = System.Text.Encoding.ASCII.GetBytes(text);
byte[] hashValue = GetMD5(message);
string hashString = string.Empty;
foreach (byte x in hashValue)
{
hashString += string.Format("{0:x2}", x);
}
return hashString;
}
private static byte[] GetMD5(byte[] message)
{
MD5 hashString = new MD5CryptoServiceProvider();
return hashString.ComputeHash(message);
}
If you only need a quick convert a md5 string, you can use my md5 online tool.
