blowfish encryption

[jay]

Hi,
Iam trying to code the blowfish encryption algorithim & I need some help with that. hmm...trying to figure it out since a day but havent found a solution.....
So let me get to the prob directly --> In the initializion phase of the algorithim , after the p-array is declared & initialized with the fractional part of pi , it is supposed to be XORed with the Key( the key is input by the user) .
Well........my prob starts here. the array P contains hex-numbers & the array key is a string .how can i XOR these ??Isnt XOR meant for binary stuff!!
Any help or suggestion is "highly" appreciated .....thnks. please refer: http://en.wikipedia.org/wiki/Blowfish_(cipher)

Hex-numbers are typically just another way to write down binary data because it's easier to read that way. String characters are represented by binary data, therefore can easily be converted to hex. They're all just numbers. I'm not a Java person, so I don't know how, but it should not be a problem if you go looking around for it. If need be, you could use a lookup table, but there must be a more attractive solution.

That more attractive solution could be as simple as this:

String MYTEXT = "My encryption Text";
//Convert the String into Bytes
MYTEXT.getBytes("UTF-8");

If that doesn’t help at all try posting your code here so we can have a better understanding of problem and maybe be able to give more detailed answers :)
