Decrypting a password-encrypted pdf (Windows)
Raw
instructions.md

This works even if the pdf is password protected with a user password (instead of an owner password), but you must have the password. It won't recover the password, just decrypt it.

  1. Download pdfcrypt1.0.zip from http://soft.rubypdf.com/software/pdfcrypt
  2. Put the encrypted pdf in the same directory as pdfcrypt.exe (and rename it to something w/o spaces like enc.pdf)
  3. Execute .\pdfcrypt.exe enc.pdf output.pdf decrypt [password] which will decrypt the pdf to output.pdf.
