Introduction
------------

This program (Advanced PDF Password Recovery, or simply APDFPR)
can be used to decrypt protected Adobe Acrobat PDF files, which
have "owner" password set, preventing the file from editing
(changing), printing, selecting text and graphics (and copying
them into the Clipboard), or adding/changing annotations and
form fields (in any combination). Decryption is being done
instantly. Decrypted file can be opened in any PDF viewer (e.g.
Adobe Acrobat Reader) without any restrictions -- i.e. with
edit/copy/print/annotate functions enabled. Please note that
APDFPR doesn't work with documents which have user-level
passwords (preventing the files from being opened), if both
user and owner passwords are unknown. Can operate in a batch
mode (with parameters supplied in the command line) to process
a few PDF files at once. All versions of Acrobat (including
Acrobat 5.0, i.e. PDF 1.4 specification with improved security)
are supported.


Requirements
------------

- Windows 95, Windows 98, Windows NT 4.0 or Windows NT 2000
- about 600 kilobytes of hard disk space


Known bugs and limitations
--------------------------

The program can process files encrypted in mode 1 with
standard, FileOpen (FOPN_fLock) and BPTE_rot13 encryption
handlers only. The documents protected with any other
encryption handlers (like SASS_INTERNET_STDS from
Standards Australia Software Services, or SoftLock's
Acrobat Security Plug-Ins) cannot be decrypted.

If the PDF file has a "user" password set (i.e. you have
to supply the password to open the file in Adobe Acrobat
Reader), APDFPR can decrypt it (removing the protection)
only if you know either "user" or "owner" password. The
user password itself can be recovered using brute-force
and dictionary attacks only (which are time-consuming);
if you're interested in such features, please look at
"professional" edition of APDFPR:

Registration
------------

Unregistered (trial) version decrypts only first 10% pages (but
at least one page) of the documents, and replaces all other pages
with blank (empty) ones. Also, it doesn't support command line
interface.

After you register (look at "order.txt" for details), we'll
send you your personal registration code. To enter it into the
program, just press the "Register" button on the main screen;
the program will display the small window dialog asking you to
enter the code. If the code is correct, APDFPR shows the message
that it is registered now, and so since than has the full
functionality.

Please note that your registration will be valid for all future
versions of APDFPR -- it means, that they will be free for you.
