Public bug reported: 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. ** Affects: pdfcrack (Ubuntu) Importance: Undecided Status: New -- pdfcrack description/docs should mention other ways to access pdfs https://bugs.launchpad.net/bugs/224562 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
