Beginning Of An End

After a while, i think there are some major differences between science and computer science. Although computer science is the sub set from science, the science in computer are always growing compared to science. For example if you continued your studies in a science faculty, the notes used maybe 10 to 15 years old right?!..

Compared to computer science which the technology are rapidly growing. Broadband, wireless and bla..bla..In the early days they said that wireless cannot be achieve but now there are more than wireless tech.

The point here is that being a computer science degree graduates and also lecturer of computer science are really a tough work. I really respect the lecturer in my faculty especially Dr. Ling..hehe..such a die-hard-networkers dude..although that i was always getting scold by him, it’s worth it.

Learning from him is really an honor for me..opss..i am beginning to write things that are not related for the title…who care’s,it’s my blog anyway..hehe..

have a nice day you all

Arghh…my final year project due date is 3 more weeks..although i have finished my Smart Encryption System..seems that the result are way to simple for me alright. Encrypt any files using any of three encyption algorithms.

Well, i thought that i want to add some steganography  function in the system.emm..i try, i said to my lovely supervisor. Got to work hard for these coming three weeks.

Happy blogging blog-hoppers..Before i finish my post..have you watch Jumper?!..totally cool movie, wish that i got that kind of power..save money and energy.

For the second time, happy blogging and have a nice day blog-JUMPER.

As i thought that my final year project are finished…not just yet as my triple DES algorithm are not running in the .jar file. After running it with command prompt i discovered some errors…damn!!!..


Triple DES used 112 bit or 168 bit key. That was the problem as the password which will be the based for the key, must be entered must be at least 24 characters. Who would do that, only super duper genius would like to put such a long password.

Now i must search a way that i can increase the bit into 112 or 168.

As a networking student, i should know about this as this is the easiest way to practice my networking skills. Although some of the protocols are not in the application, it’s really worth a try.As the lab in my faculty are shared with other students such as the master students. The router and switches are also limited. Sometimes i didn’t get to finished my lab work cause sometimes they will be class conducted in the lab.


If you want to download the Packet Tracer, click part 1, part 2 and part 3.

Have a nice day to all networkers all around the universe!!!..

3DES or Triple DES or DESede are well known encryption algorithm which are the “child” of DES(Data Encryption Standard). Although it was replace by AES (Advance Encryption Standard) still there are some people like me studies this old thing.

Triple DES is part of my final year project. I asked my lecturer if i perform DES three times, is it same like Triple DES. The answer is NO because Triple DES use different keys.

The keys use is 56 bit. I just finished a simple JAVA application on Triple DES. The application receive input and password from user. Then display the output which the user can choose between encrypt or decrypt.

If you want to try my newly developed JAVA application, you can download it here. If you want the sample of the code?!Please contact me at n a w u z a at g m a i l . c o m.

Above is the screen shot of my JAVA application.

I just have upgrade my graphic card(ASUS A9550GE) from 128MB to 256MB just for RM130.hehe..Acop bought a new graphic card which he want to install it to his friend’s computer unaware that the computer motherboard are broke already. Acop then decide to sell the new graphic card to me for RM180 but after i trade my old graphic card for RM60 i only need to pay RM120.

Now my computer can sustain heavy graphic playing games and etc. But now is not the right time for me to play more games as i must finished my project and study for final exam. Above is my graphic card.hee.

I am doing my final year project about encryption using three algorithm. My project use JAVA as its platform. My part is done as i am waiting for my friend’s part and voila…Past my project with flying colors=)

Let me brief you all about mine Smart Encryption System.

• user were asked whether they want more security or high speed encryption
• then user will be asked which file they want to encrypt,where you want to save the encrypted file and also a password to encrypt the file
• the system will perform some process to select which encryption algorithm are the best for the file
• voila..user have transform their file to be unreadable.

Although i have no basic in JAVA, it’s not much of a problem as the programming is similar to C++ programming which i have learn for more than two years.
