Encrypt PDF

- Version 4.0.1.5

PDF Encrypt software is a very flexible and powerful
program, it allows you to encrypt (using standard
40-bit or 128-bit or AES encryption) existing PDFs, set
permissions, add user and owner password. For example
you can encrypt a PDF without allowing to print it. The
button to print the file will be disabled in Acrobat
Reader application, you can also encrypt a PDF to allow
the user to read it only if he knows the correct password.

There two passwords you can apply to a PDF. The first
is the owner password. Opening a PDF with this password
will allow you full access to the PDF when a user
password has been assigned as well. This means that
even if printing was disabled you will still be able to
print the PDF when using this password. No password
will be prompted for when opening the PDF if you secure
it with only an owner password. The second is the user
password. Opening a PDF with this password will
restrict you based on how the PDF was password
protected (printing may be disabled, for instance).
