Protected PDF Password - I know most of it

[xelwenq]

Hi.
I have a PDF of a medical report from may this year. I know most of the password and what characters will be used in it. Its the format SurnameInitialDateofBirth or in any other order. Maybe without full DOB or no initial
I really need something to check permutations. I remember the password being given to me back in May. But now I need for 9am tomorrow morning as I have another check up (I didn't realize due to my illness.)

Anyone have any ideas what I could do or know any software to try permutations.

Thanks

Have you tried to BruteForce it? If you know the characters, it would make your work much easier.

YOu may try brute forcing

actually found this http://blog.rubypdf.com/pdfcrack/

currently bruteforcing with a charset that only contains characters in my name and numbers averaging 63504 w per second. I hope this is fast enough.

Any luck? Did you manage to crack your password?

Didn't in the end. I have the password in work but I wasn't going in today.
Thankfully they will let me send this to them next week.
