AES S-box question
I am implementing Rijndael Advanced Encryption Standard (AES). In the specification document the S-box used in the transformation routine is presented. Does this mean that the S-box does not need to be kept secret? Or should I generate my own S-box and inverse S-box arrays? If so can any one point me to where I can find an algorithm to generate the S-box.
Regards,
Alex
Not a Java question. You might try posting to sci.crypt on Usenet: http://groups.google.com/group/sci.crypt/search?q=AES+S-boxes&

on some websites the images does not show, instead it just shows blue box question marks. I'm using a macbook air with Yosemite 10.10.1 and Safari 8.0.2. What can I do to make it show the pictures?
The server hosting the images may not be available.

What are these blue box question marks?
What are these blue box question marks appearing on some websites?
They seem to not appear on every website I visit, only some.
I have tried several troubleshooting steps.
-I reset cache.
-I changed text encoding.
-I checked bos to always display images.
-I went to "develop" and opened in every other browser.
-I updated my adobe flash player.
What else can I do?
It is so annoying!
I am running Safari 8.0.
Thank you!Here is a screenshot of the page:

Hi all,
On the VAT declaration box report it puts in a zero figure for EC Acquisitions which is incorrect so we have to do a purchase analysis report in order to obtain the correct figure u2013 can we set this up so that the figure is correct?
Thank you,

Hi all,
Our BI has been already upgraded to 7.0. Currently connected to R/3 4.7.
Now a new box is made with ECC 6.0 and Oracle 8 which is a mirror copy of the r/3 4.7.Once the new box is ready the BI 7.0 connection will be switched from R/3 4.7 to the new box ECC 6.0.
My question is ...
In the R/3 4.7 the datasources were already initialized for delta..so the pointer for delta was already setup.
Now when we connect the new ECC box do I have to initialize delta again ? or would the new system recognize the pointer since it is a mirror copy from the old system?
pls adviceIt´s a bit confusing what you write - I try to get your point:
- your 4.7 is running on Oracle 8 (VERY old, unsupported)
- you install a NEW system on ERP 6.0? Or do you upgrade your 4.7 copy?

Hey all, I am currently working on a project and have run
into a snag and cant seem to find the answer, or even if what i
need can be done.
Question 1: how do I advance a slide with the correct entry
of a text field without a button or keypress?
Question 2: if this is not possible, how can i have a text
entry box check for correct input using a custom button?
Any help would be appreciated, Thanks.
M. AndersonHi M. Anderson
The first question may be accomplished if (and only if) the
last letter the user is supposed to type is unique among all the
letters. For example, BOFFO would not work. O occurs twice. But
LIFE would work, because E is unique. You could then configure the
letter E to be the shortcut for the Text Entry Box.
For the button, it's pretty easy. Click the Options tab and
look at your choices. Make sure the "Button" option contains a
check mark. After you dismiss the dialog, you end up with a rather
generic looking button. But once you enable the button, you may
then double-click it to edit its properties. You could choose an
image, or you could make it invisible and position the invisible
button over another image you placed on the slide as a simple image
object.
Hopefully this helps some... Rick -
For some reason all my songs have become unchecked. I don't know why. Is there an easy way to recheck them all. Rather than having to click in every box? It seems that because the aren't checked Genius will not recognize them. They were all working until today.

I copied 250 gig of music from my old pc hard drive to my desktop. I just imported them to iTunes by adding them to my library. Now that the music is all in iTunes, I can delete the large music file on my desktop?
This is another topic that should have it's own thread.
To answer your question. It depends on if you had <iTunes/Preferences/Advanced/Copy files to iTunes Media folder when adding to library> checked. If the files were copied then you have duplicates and the files on the desktop can be deleted. If the files were not copied then the files on the desktop ARE your music files.

Can I create a text box in Pages that can automatically scale vertically to fit the text inside?
I'm trying to create a modular element for a template that someone can paste any amount of text into without having to manually change the vertical scale of the text box.Answered my own question.
Instead of creating a text box, create a table cell. -
Hi guys,
Firstly a very Merry Christmas to you all !
I'm just getting to grips with converting all the text on my
site to CSS and have a quick question.
On some of my pages I add an 'Also see' links box aligned to
the right - it's a CSS div tag thingy someone kindly talked me
through once. All of my pages are built from a template with an
editable region.
My question is, can I add this box (perhaps with a standard
'Also check out' title and then spaces for my links) at the
template level? This will save me having to go to Insert>Layout
Objects>DivTag on every page. I've tried simply adding this to
the editable region of the template but it simply pushed the
editable region box over to the right and then didn't appear on my
pages
Also, the links box would ideally appear about half way down
my pages on the right...
Hope you can help, many thanks in advance!
James
Here's an example page where I have manually added my link
box on the right of the page...
http://www.fyrne.com/james_journalism/Pages/Mosaic_of_the_med.htmlYour CSS link implies that the CSS file is in the Templates
folder. You
shouldn't have anything there other than the template (dwt)
files
themselves. Please move it out to any other location in your
site.
<link href="../../Templates/Box.css" rel="stylesheet"
type="text/css">
Changes made to template editable regions would not propagate
to existing
child pages - that's why you aren't seeing that addition in
them....

I am seeing a weird behavior with single select list boxes. If you want to select an item in the list box you click on it. My question is how do you deselect the item? If you click on it again the item should be deselected, but in this case it stays selected. You can select other items but you can never turn the select off.
Hi,
The workaround for this scenario would be to add another item "None" or "Select One". Like in a drop down list, an item once selected cannot be deselected. The only way to deselect an item would be to select another item. I hope this helps you.
Cheers :-) -
Hi everyone. Quick question. I am curious if there is a way for my iTunes to shuffle and play songs that do not have the box checked. I like to keep certain songs/albums unchecked so I can switch up what's on my iPhone, but still have the ability to shuffle through while listening on my laptop. Thanks in advance.
No this is exactly how unchecking is supposed to work. Unchecked songs wil not sync or play as part of a playlist.
If you want to add new music to your device set up a Smart playlist with the correct criteria and sync that. -
Does the new Vision + box run extraordinarily hot by design ?
I have the new box and the fan at the back never seems to come on. The box gets incredibly hot during operation, far too hot to touch the surface.
I cant believe they designed the box with a redundant fan so my question is.....
Should the fan be turning in the new black Vision + box.Hi Cypher and welcome
To answer your question I don't know so I too would like to find out.
I have a silver box switched on and the top cover is cool to the touch.
I also have a black box switched on and the top cover is on the upper scale of warm (I can hold my hand on it indefinitely though).
The fan on the silver box is on.
The fan on the black box is off.
Having said that I believe the fan is controlled by the software so it's possibly been tweaked to make it more energy efficient.

Blue Boxed Question Marks In Safari...HELP
Hey Guys,
Just messing around with iWeb and created a quick site at:
http://web.mac.com/tjmerwanji
I've noticed these blue boxes with a question mark in them in numerous areas, in place of some pictures or sometimes just randomly
Looked through the forums about text encoding and it didn't work or I'm doing it wrong
Just published normally to .Mac using iWeb,
Really need help!
Any ideas?Hi,
I'm using the black template (i think), and I tried to add the "Add Comment" function. The i republished, and now i get is the '@post" where "add comment" should be....
Also on my blog entry page all the link functions ie. a link, Email Me, Read More, Add Comment...all appear as blue square with questions marks. But if you click on the blue squares the links do work and it takes you through to the page you want. All images etc are still there, it's just the links that have the questions marks.
http://web.mac.com/jeremysuttonhibbert/iWeb/TokyoLand
If anyone has any suggestions other than just sitting it out and see if Mac sort it, it'd be great to hear.
Thanks.

Blue boxed question marks on photos after publishing?
All of my photos have white question marks in blue boxes when I publish my site to my FTP server. I've read where this is caused by pictures not being linked properly, but I have re-linked and have left the location of the photo file unchanged, to no avail. I've contacted Yahoo (my provider), also to no avail. I have not fully published my site to my domain yet due to this, but this is the URL of my temp domain:
http://nashvilleleader.com.p8.hostingprod.com/Nashville_Leader/Home.html
Any help would be greatly appreciate. Thanks!The files haven't been uploaded. Take a look at the Activity for your home page, Option-Command-A, to see the URLs of the missing files.
Look HERE to see the directory and note that the files aren't there.
How are you uploading the files - iWeb FTP, an FTP app or Yahoo file manager?
Good luck with getting help from Yahoo - their tech support is the bottom of the barrel. -
Does anyone know if the same firmware is installed in both sw1 and sw2 on a C60 out of the box???
SECOND QUESTION: What if any is the process to factory reset a C series codec if for some reason unable to use the serial port????
Thank You.Hi
Only one of the memory banks should be populated with a software version out of the box.
The second question depends on which C-series codec you mean. C20 can be hard factory reset (power button sequence) while C40, C60 and C90 cannot and must be done either through serial, web, touch, telnet or ssh where all of them except serial requires a network connection.
