I have a PDF. I know its password is composed of 8 characters. First four
letters are known (as they belong to my name). The last four are digits. So I
created this word list with a combination of all of them. For example, if
letters were ABCD, my word list would be:
Yet the pdf crack is not working. When I execute the command, it returns
almost immediately, and the following output is produced:
$ pdfcrack -f mypdf.pdf -n 8 -m 8 -w wordfile

Could not find password
What could be the reason?
I am positive about the four letters (as they are four initial uppercase
letters from my name). and for the numeric part I am taking all combinations
anyway.

Hi,
I have a PDF. I know its password is composed of 8 characters. First four
letters are known (as they belong to my name). The last four are digits. So I

ABCD0000
ABCD0001
ABCD0002

ABCD9999
Above ... represents all combinations in between.

I have the same problem. There is not much instructions for this.
checki if this is a user or owner password
it's user password, there are sites that can crack owner passwords online. anyway, I tried both -o and -u. same result.
