I’m wondering whether there is a way to encrypt my entire drive so that nothing on the drive can be accessed without an encryption key upon booting? I’m looking for something that’s open source and runs under Linux. I have heard things about PGP, would that be able to do the job for me? The level of encryption has to be strong, preferably government level.

encryption decryption java coding?

You have just been hired by the CIA as a programmer in the encryption department. Your job is
to write a class called Crypto. One method, encrypt, will accept a String that represents the sentence to be encrypted. It will return a String that is the sentence with all v’s (big or small)
replaced with “ag’,r”, all m’s (big or small) with “ssad”, all g’s (big or small) with “jeb..w”, and
all b’s (big or small) with “dug>?/”.
The class contains another method, decrypt, that accepts a String that represents the sentence to
be decrypted. In this method the reverse process described above is performed. It returns a String
that is the original sentence before encryption.
Use the following Tester class to insure that your methods work.
import java.io.*;
import java.util.*;
public class Tester
{
public static void main(String args[])
{
Scanner kbReader = new Scanner(System.in);
System.out.print(“Enter a sentence that is to be encrypted: ”);
String sntnc = kbReader.nextLine( );
System.out.println(“Original sentence = ” + sntnc);
Crypto myCryptObj = new Crypto( );
String encryptdSntnc = myCryptObj.encrypt(sntnc);
System.out.println(“Encrypted sentence = ” + encryptdSntnc);
String decryptdSntnc = myCryptObj.decrypt(encryptdSntnc);
System.out.println(“Decrypted sentence = ” + decryptdSntnc);
}
}
Test with this sentence: “This is a very big morning.” After running your program, your screen
should appear as follows:
Enter a sentence that is to be encrypted: This is a very big morning.
Original sentence = This is a very big morning.
Encrypted sentence = This is a ag’,rery dug>?/ijeb..w ssadorninjeb..w.
Decrypted sentence = This is a very big morning.

well , i am realtivly new to linux ( ubuntu , knoppix )
im going to be going to college soon , and im wondering what sort of jobs would i look at that could require me to use linux ?
i currently know html and am pretty fluent with html , wordpress and style sheets
im working on learning php , and i know a very little amount of python ( basically nothing)
so i guess what im wondering is how do i further my knowledge from just using the os ( i know some things like using terminal , , gedit , sudo …small stuff like that)
but i want to focus my trainign to a specific job soon , and any studies i can do on my own are only going to help me
the reason i was thinking linux , is mainly beacause linux seems like an os that you can really learn … you can "get your hands dirty" in the actual os
but , if you think i would be able to have a more succesfull career with windows then please say so

and what are some future computer related jobs that are going to be in high demand ?
tahnks for your help , it is very much appreciated

WordPress integration questions?

I contacted my webhost to find out on whether i can run WordPress?

I’m an absolute beginner. I want to be able to keep my site fresh and up to date with articles and images. And i’m assuming wordpress can get the job done. The thing is my site was developed using xhtml and css. How can i integrate WordPress for this site.

This is what i sent to my webhost (got this from the wordpress.org website).

I’m interested in running the open-source WordPress blogging software and I was wondering if my (www.energyworkforce.net) supported the following:

* PHP 4.3 or greater
* MySQL 4.0 or greater
* The mod_rewrite Apache module

And this is the reply i got from my webhost…

hosted under Windows Platform. It support PHP, MySQL but do not support for mod_rewrite Apache module. You might need to transfer to linux Platform.

Now what do i do? What is this mod_rewrite Apache module. What does it do? And whawwt is my next plan? Do i move to a Linux Platform as advised or can i still use WordPress with the Windows platform.

I know i’ve asked alot. Thanking you all in advanced.
