Bug Description

Binary package hint: pdfcrack

The pdf encryption key only depends on the user password (and information that is stored in the file, like the hash of the owner pwd.)
e.g. see http://www.cs.cmu.edu/~dst/Adobe/Gallery/anon21jul01-pdf-encryption.txt

 If it's not illegal[1], pdfcrack should point out that if you don't need a password to view the pdf, it can be completely decrypted by e.g. pdftk with the password checking commented out. Enforcing the owner password in PDF encryption is entirely optional, in a technical sense. The legal sense is another matter, and even talking about things, let alone distributing software that ignores restrictions, might be illegal in some parts of the world.

 I wish I'd known this; I wouldn't have tried pdfcrack, since I just want to merge some user pass="" PDFs.

[1] DMCA in the US, and all those garbage laws spreading to other countries too.
