<P align=left><font size="2" face="Verdana">PDF Password Cracker
Enterprise edition allows to search for "owner" and "user" passwords with
brute-force and dictionary attacks, effectively optimized for speed
(however, don't expect to recover long passwords in a reasonable time with
these attacks). In addition, it has Key search attack, which guarantees the
decryption (regardless the password length and complexity) of PDF files that
use 40-bit encryption (the attack takes about 3-4 days on fast CPU
systems). <br>
<br>
The standard security provided by PDF consists of two different methods and
two different passwords. Owner Password allows to prevent PDF file from
printing, editing (changing), selecting text and graphics (and copying them
into the Clipboard), or adding/changing annotations and form fields; User
Password locks the file so the password is required to open or view the
file. If only owner password is set, 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. Alternatively, owner password can be recovered using brute-force or
dictionary attacks. <br>
<br>
Additionally, PDF Password Cracker Enterprise supports "key search" attack that
allows to decrypt (in a reasonable time) PDF files with 40-bit security
regardless the password length, guaranteed.</font></P></BLOCKQUOTE></BLOCKQUOTE>
