Hi,
I want to ask your help. How come I can test the effectiveness of using RSA
2048 bits with RSA 1024 bits? What the tools I can using to test this two type of algorithm? Because I need to get the result for my final project.

Define "effectiveness" ?

Hi Mehdi

Here is brief about my project. Im setup 2 cloud computing application. One applied a SSL with RSA 2048 bits key and another one applied SSL with RSA 1024 keys. I understand that my cloud application is secured enough for the basic of security. So, what can I do to prove that RSA 2048 is better than RSA 1024 on practical part. maybe the result is about the speed of the encryption or decryption process? What can I do to test the both type of keys??

Learn how RSA works...
Understand that RSA can be brake in the theoretical level, but in the practical approach it depends on the bit size of the key used... From all your knowledge, define the 'effectiveness' of the different bit-sizes...
Conclude...

Hi Kornfeld,

What im tried to do is doing the testing into RSA 2048 and RSA 1024 and do the comparison with the practical result saying that RSA 2048 is more preferred than RSA 1024. How can im doing the testing?? On the basic and simple one. Just want to get the result..

In security the more bits for a key the better, you don't need to test that or to prove it.

Hi Mehdi,

Yup. I knew it. Thanks for it.. The thing is I want generate a report.. A practical report such graph or analysis instead of the theoretical one.

To prove that 2048 bits are better than 1024 bit all you need is math!
Hint 1: 2048 bit has about 4.3 billion times the variations 1024 bit has...
Hint 2: In an average desktop computer (2 cores 2.6) it will take 1.5 million years to break 1024 bit
Hint 3: There are much faster CPUs (GPU in fact) so time can be less, but still we talk about hundred of thousand years
Hint 4: Hundred of thousand years of 1024 bit multiplied by 4.3 billion is very long time...
Hint 5: Learn RSA
