Unlock Secure PDF

[ezninnovation]

One of our clients has started adding security to the pdf files and now quite hot imposing fails because it is password protected. I have the password, but what is the best way to check if the pdf is pw protected and then use the password to unprotect it.

You can use a Preflight to check.

If need to you can use
https://pdfkey.com/en/
Automation Tools: Includes command-line tools to allow integration in complex workflows
and the CLI in Execute Command to unlock most PDFs.

You route jobs with this condition:

These files have security enabled.
Then you could use a cli tool as this https://sourceforge.net/projects/pdfdecrypt/ to remove the security since you know the password.

If you have the password for a PDF and need to unlock it, you can use also PDFTK along with the Execute Command app.
You can refer to the official documentation for more details :https://www.pdflabs.com/docs/pdftk-man- ... c-owner-pw
