How to bypass a PDF password
I created a PDF document of around 2MB file size and then went to Protection. Added both password to open and edit, both with 256-Bit AES. Saved the file with a 25 characters password.
Now I Googled this "How to bypass a PDF Password", the third link is this "https://smallpdf.com/unlock-pdf".
I dropped the encrypted file into the slot provided. assuming that it cant ***** it.
But unfortunately the password was cracked both from the opening and editing end.
I find this very disturbing !
Kindly check this and let me know how to ensure that a password protected PDF not be cracked.
The file I is a Non-Disclosure Agreement (NDA) file so I wont be able to share it here.
It would be great if you could help me out to understand how to ensure such a thing does not happen.
