Support for algorithm - pdf v1.1 - 1.3 owner password #929
Currently Hashcat (3.10) supports the user password, but does not support the owner password. Can we add support to handle the owner password too?
Owner password can be used to lock down permissions, preventing printing/changing.
for you interest, I confirmed here: https://hashcat.net/forum/thread-6233-post-33255.html#pid33255 that the algorithms used for owner password vs user password are just slightly different (the example was with revision 3 PDF 1.4 - 1.6).
