So, regarding this encrypted PDF…

I researched multiple articles. I tried strong PDF editing tools… no dice due to the encryption.

So I researched again. More articles. Downloaded one package- no dice. Downloaded another package and ran it from the command line:

jktuxbox@tuxbox:~$ cd _Temp/
jktuxbox@tuxbox:~/_Temp$ cd da4651/
jktuxbox@tuxbox:~/_Temp/da4651$ ls

That’s right- the password to decrypt the file was one keypress of the spacebar. *Epic facepalm*
