Encryption algorithms

Posted 13 August 2007 - 07:57 PM

hello everybody;

i am student from malaysia, here i need help from you all, for your information, i am working for my final year project now, My project is Smart Encryption System which it can encrypt all type of files and sizes. i decide to use java programming because there are many coding available. i also used 3 algorithm to encrypt/decrypt the file which are DES,3DES and Blowfish. because i am very beginner user, where i can learn the java programming. some one can suggest me what the 3 best algorithm easy to use with java.

tq.

You should read this - http://java.sun.com/...CryptoSpec.html

It gives information about the cryptography architecture in java.

Update : More recent link provided in the post directly below this

As csmanoj wrote, have a look at the JCE, but since J2SE 1.5 it is integrated into the SDK I would assume this more recent link.
It has everything, even sample codes.
Since it is a framework, the algorythms are equally easy to use - maybe those taht use public and private keys need a bit more attention, than secret key ones. (I would only suggest reading up on their main features, because some of them might need extra care taken, like RSA needs padding for large data, or effective keylength)

Are you asking about compilers or IDEs? Netbeans and Eclipse are IDEs, and they both use whatever compiler (SDK) you configure in them (the most common is SUN's, but there are a couple of others).
For a compiler I would stay with the SUN SDK.
There are a couple of threads here on IDEs, they both have their advantages and shortcomings, but for general Java apps, there is not much difference.

sorry friends,actually i very beginner..what is the difference compilers or IDEs?let say i want to built the java app, did i need to have both the compilers or IDEs?

You need a compiler, and you can use an IDE to make your life easier (it's only a graphical user interface, so you can point and click on commands, automates some actions, and makes editing your code easier via syntax highlighting), whereas a compiler is usually a command line program, that creates an executable (or object, lilbrary, whatever) file from your source files.

where i can find free source code for encryption and decryption in java?..anyone can suggest me what the best compiler and IDEs to used for my system? :) because it require three algorithm together in the system..

A link is already posted in this thread. (Hint: by me)

The standard Sun compiler will do, and both Eclipse and NetBeans are just fine as an IDE, but generally any modern IDE will do - and it isn't overly complicated to do even without an IDE.
