Hello!
I'm working on an project and want to use MD5 algorithm but I was trying to write my own algorithm witch will works as the same as MD5.
At first I was writing in MS Visual Studio using a System.Security.Cryptography libryry:
using System.Security.Cryptography;
public string encoding(string testText)
{
//Declarations
Byte[] originalBytes;
Byte[] encodedBytes;
MD5 md5 = new MD5CryptoServiceProvider();
originalBytes = ASCIIEncoding.Default.GetBytes(testText);
encodedBytes = md5.ComputeHash(originalBytes);
return BitConverter.ToString(encodedBytes);
}
Now I want to implement the same algorithm, self-writed but without included librarys witch must return the same value. I have to write an code witch assign a hash code to some input string (like testText in function).
Have anyone some idea?
Thanks a lot!
Benny

Why do you want to reinvent the wheel? Why not use the code that is already built in to the .NET Framework?

The internet is a powerfull thing.
But really, it won't be your own MD5 algorithm, it will be the md5 algorithm.

Incase you can't read, follow links, simply don't notice it. Full C code for the MD5 algorithm is supplied with rfc 1321

Why would you want to replicate the code for an algorithm known to be weak anyway??

Are you still going on about this? If you need to hide your IP address then use an anonymous proxy. Or something like Tor (as was previously recommended to you)

You've been watching too many movies. It's not possible to hide your IP address.
By the way, we're sick of repeating ourselves. Stop asking this question. It simply cannot be done. If you change you spoof your machines IP address, you won't get a response back from the server you're sending your request to. It'll go to wherever the IP address REALLY is.

How to provide secuity for webservices using c# ?
what are the ways to provide security for webservices? How can we implement this?
any one have idea regarding this, please help me?

It really depends what you mean by security. I would start though, by reading up on WSE 3.0.

Great Pete. This is really a new information to me. I used to secure my web services using a simple user authentication. It works fine till now. But looking into WSE, I got doubts on my method. Do you think the method which I used is correct ? Or what you can tell as an advantage for WSE ?
|
|

As I said before, it depends on what you are trying to achieve. If you only want to verify that a user should have access, then simple authentication is normally enough. If you want more control, say to encrypt the data that is being transmitted over "the wire", then WSE 3 is a much better choice.

With WSE you can implment various filters wich inturn helps you provide more secure communication. Also using digital signatures i.e. X.509 can help you provide more secure communication.

To display dynamic images on Crystal reports, you should keep your image in database as a BLOB data. Bind it to the report and it will show as image. I don't know what you meant by "Editing the image".

Hello friends,
I want to construct an array which consist of 9 members.,(for example int[] sayilar=new int[9])
We construct the array members randomly.
The members of array must be between the number of 1 and 9.
and The values of sayilar[1] musn't be valuef sayilar[2] and the value of sayilar[4] musn't be value of sayilar[6].
For example, we give 7 to sayilar[1] as randomly, sayilar[2] must be different from 7.
Can you help me?
