Hi, I have a method written in c# to get md5:

    public static string encryptPasswordWithMd5(string password)
    {
        MD5 md5Hasher = MD5.Create();
        byte[] data = md5Hasher.ComputeHash(Encoding.Unicode.GetBytes(password));
        StringBuilder sb = new StringBuilder();

        for (int i = 0; i < data.Length; i++)
            sb.Append(data[i].ToString("x2"));

        return sb.ToString();
    }

now I need to implement the same function using objective-c, how to do it...
