dari awal gw agak bingung..
"pdf agar bisa diprint diword" maksudnya gmn?
apa maksudnya convert PDF jadi DOC?
soal decrypt-nya, ini gw kupes postinganku dari sebelah..
PDF security overview
The standard security provided by PDF consists of two different methods
and two different passwords. A PDF document may be protected by password
for opening ('user' password) and the document may also specify operations
that should be restricted even when the document is decrypted: printing;
copying text and graphics out of the document; modifying the document;
and adding or modifying text notes and AcroForm fields
(using 'owner' password).
ada 2 proteksi pass:
1. User Pass: utk read/buka PDF
2. Permissions/Owner Pass: utk modif/edit/print/copy isi.
naa.. kebanyakan program decrypt cuma support remove OWNER pass,
di antaranya (gw tesin satu² neh):
- 3A PDF Password Remover 2.0
http://www.aaapdf.com/pdfdec/pdf-password-remover.html
- Adult PDF Password Recovery (remover) v2.4
http://www.adultpdf.com/products/pwdremover/index.html
- Elcomsoft/Dmitry Sklyarov's Advanced E-Book Processor 2.2
http://www.cs.cmu.edu/~dst/Adobe/Gallery/
- Guaranteed PDF (GuaPDF) Decrypter-Restrictions Remover 2.21
http://www.password-crackers.com/service.html
sedangkan yang bisa recover USER pass:
- Elcomsoft Advanced PDF Password Recovery Pro 2.21

- PDF Password Cracker Pro 2.0

gw tes deh bikin PDF pake Adobe Acrobat 3D v7.0.85
trus dikasih user & owner pass.
utk USER pass cuma bisa pake metoda brute-force / dictionary
kek RAR/ZIP Pass recovery.
pake PDF Password Cracker Pro 2.0 jelek.
gw kan udah tau pass, trus gw set min-max karakternya,
masa pass-nya gak ketemu juga.
pake APDFPR Pro baru oke..!
Elcomsoft Advanced PDF Password Recovery Pro 2.21
http://www.crackpassword.com/products/prs/othersoft/pdf/
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 Acrobar Reader) without any restrictions --
i.e. with edit/copy/print functions enabled.
The program is also able to convert Kinko's Document Format (KDF)
files to PDF files (without any protection).
Professional edition also 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 resonable 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 modern
dual-CPU systems).
Warning: APDFPR does NOT work on Mac computers with Virtual PC;
unfortunately, it seems to be a problem of Virtual PC itself.
Native Mac version of APDFPR is under development.
