It does not exist as a functional tool. Use alternatives listed in the how-to section.

What this does not protect

  • Password-protected PDF writing is not implemented. This tool does nothing.
  • Even when implemented, PDF password protection is weak by design. RC4 and AES-128 encryption in PDFs are well-understood and quickly crackable.
  • It cannot fix compromised devices, accounts, or unsafe sharing channels.
