Ummmm....
<https://www.elcomsoft.com/apdfpr.html>
$50, $100, or $400 versions.
<https://www.elcomsoft.com/WP/guaranteed_password_recovery_for_adobe_acrobat_en.pdf>
Made in Russia.

The $50 version is rather basic and can take several days to crack a
basic 40 bit RC4 encrypted file.  256 bit AES encryption can take
forever.  The $100 version is better but lacks rainbow tables, which
really speeds things up.  For rainbow tables, you'll need the $400
version.

Ouch. Most of them are 'instant'. I think the program is 8 or 10 years
old. It's certainly not worth $400 to me.

I have a customer that does computah forensics.  They have the
enterprise version, which they let me use when the need arises.  The
rainbow tables don't always produce spectacular results, such as when
the password is all symbols, but is a major improvement.

I just tried the trial version of the program:
<https://www.elcomsoft.com/download/apdfpr_setup_en.msi>
on one of the PDF test files I found at:
<http://www.novapdf.com/kb/pdf-example-files-created-with-novapdf-138.html>
The 2nd file, which is password protected, uses a not so clever
password = "test".  I ran the program with a dictionary attack and it
took about 3 seconds to find the password.  I then ran it with a brute
force attack, using all possible symbols except space, and it took
17.5 minutes.    On the brute force attack, some stats:
   Passwords to process  78,914,410
   Work time             17m 35s 725msec
   Average speed         74,749 passwords per second
Not too shabby methinks.  
I'm running a rather dated Dell Optiplex 960 3.1GHz E8500 Dual Core
with 4GB RAM and WinXP.

Can someone point me to an encrypted NXP data sheet so I can see if
and how it works?  I'll guess(tm) that NXP uses a rather primitive
encryption key, such as the part number backwards.  I dug through my
mess of saved data sheets and couldn't find any that were encrypted
and/or password protected.  Random downloads from the NXP web pile
didn't do any better.

 My example was a simple Schottky diode, PMEG3010.
 I'm looking at rev 4 of the datasheet, dated 2007.
 I can give you hundreds of others if you need them.

 Most datasheet encryptions don't prevent you from
 seeing or printing the datasheet in toto; they
 prevent you from doing *any* of the other dozens
 of important ways to use a document. 

 I'm not sure what it's doing, but the program
 PDF Password Remover takes a fraction of a second.

Have you found one where PDF Password Remover _doesn't_ work?

 I have long since forgotten which one it was.
 It takes a few minutes to bring up the app,
 find and name the output file, etc., so I
 don't do it very often.  But I haven't
 encountered a failure in a long time.

Yawn, grumble, and thanks.  With inspiration provided by Jim Thomson,
I contrived a much easier way.  The problem is that it's not quite
what I expected and may not be suitable for everyone's needs.

Download and install Iranview and Irfanview plugins.
<http://www.irfanview.com>
Irfanview is a good free photo editor that can also handle PDFs via
plugins.  Here's how:

- Open the PDF file with Irfanview.
- "Save As" with a "Save as type" PDF.  
- Check the "Show Options Dialog" at the bottom of page.
- Hit "Save" button.
- A "Save PDF" dialog box will appear.  
- Under the "Security" tab, uncheck the "Activate Security" check box.
- Hit "Save" button and the view the PDF in Adobe Acrobat or whatever.

The owner password should be cleared in the resultant PDF.  You should
now be able to add annotations, sticky notes, and scribbles to the
data sheets with Irfanview (hit F12) or any PDF editor.

Some limitations, details, notes, ideas, and problems:

The process changes the text fonts to a bit mapped graphic, which
cannot be text edited.  The original NXP data sheet shows 8 fonts,
mostly Helvetica and Symbol.  The converted PDF show no fonts and is a
graphic.  The results are readable and printable, but of lower quality
than the original.  If this is a problem, you may do better with a
password cracker/remover program.

Since the converted page is a graphic, it is possible to use
PDF-Xchange Editor (free):
<https://www.tracker-software.com/product/pdf-xchange-editor>
Document -> OCR Pages
feature to recover making the document searchable.  The NXP data sheet
took about 6 minutes to OCR 11 pages.  

Under the "Save PDF" dialog, under the "Layout" tab, you can change
the page size from A4 to letter.  This is handy because I haven't
found a good way to change the document size for printing in Acrobat
or PDF-XChange viewers.

Under the "Save PDF" dialog, under the "Compression" tab, you may want
to adjust the image qualities.  I tried turning off compression, but
that expanded the original 78KByte file to about 28MBytes (with an OCR
text layer).

Irfanview can do batch processing.  
File -> Batch Conversion/Rename
I haven't tried this yet, but it might be possible to use this to
clear passwords from a directory full of PDF files.

Irfanview can be run from the command line:
<http://www.makeuseof.com/tag/10-useful-commandline-irfanview-tools-working-images/>
which can probably be used for batch processing.

<http://www.nxp.com/documents/data_sheet/PMEGXX10BEA_PMEGXX10BEV.pdf>
The Elcomsoft demo program says that the "user passsword is empty..."
However, that's the 2004 version direct from the NXP web pile.  Got a
link to the 2007 version or a better example?

Dunno.  There are two passwords.  The owner and the user passwords.
Some programs, like Elcomsoft try to decrypt the password(s).  Others,
just remove it from the PDF.  My guess(tm) is that like the 2004
version, there is password.

>link to the 2007 version or a better example?

Never mind.  I found the 2007 version on Octopart:
<http://datasheet.octopart.com/PMEG3010ET-NXP-datasheet-5392248.pdf>
Same problem.  It says "User password is empty so instant decryption
is possible".  I had no difficulty printing the first two pages of the
data sheet.  However, I was not able to add any annotations (using
PDF-Xchange Editor 5.5) because the document properties showed that
the owner password has been set (40 bit RC4).  The permission details
show that printing and content copying are allowed, but no changes to
the document, such as annotation.  I'm not sure why the Elcomsoft
program is only removing the user password, and not the owner, but
I'll see if I can figure it out.

Duh... my fault.  Under the "advanced" tab, there is a choice to
decrypt the owner and/or user passwords.  I had the wrong one checked.
It's cranking right now using a brute force attack.  The demo has a
very small dictionary, so that didn't work.  Stay tuned to this
newsgroup for the latest episode of "DMCA violations made easy".

Oops (again).  The demo version is limited to passwords up to 4
characters in length.  The NXP data sheet probably has a longer
password, so this experiment isn't going to work.  I try it on the
real version later next week.  Sorry.

 Most locked security settings do allow printing.
 Otherwise they'd completely lose the customer!

Well, in a pinch you can print it and then OCR.  Here's a shout-out to 
my fave OCR/document conversion site:

I guess that's the only thing that's keeping the lawyers at bay. 

They would probably prefer that each copy be strongly encrypted,
unprintable and each copy be watermarked in a way that is traceable to
an individual NDA.

I've almost always been able to print the PDF to a PDF, then add any
notes I want to.  However, about 20% of these can't then be searched.
So, I end up with two copies.

Why would anyone want to keep people from seeing their data sheets?
But lots of people do. 

That chip looks klunky by modern standards anyhow.

Several people make things like this:

which is astonishing, especially for $5 or so.

Totally.  The Q3236 was already 15 years old in 2008, 
and you could buy much better parts by then.  The page 
where I posted the data sheet was only meant to help me 
keep track of the programming info for an obsolete 26 GHz 
PLL brick (http://www.ke5fx.com/usrc.htm) that I bought 
from a surplus dealer on eBay.  

PSA: if anyone does need a Q3236 for anything, you can get 
a better version of it from Peregrine: 
http://www.psemi.com/pdf/app_notes/an09.pdf .  

I like Peregrine.  They haven't sent me any bullshit DMCA 
notices lately, and they make neat stuff.

They have some cool digital capacitors, SPI programmable. 

Maxim had one, but of course they EOL'd it.
