Encrypt PDF SDK-COM Component
-
Version
2.0
Encrypt PDF SDK-COM is a very flexible and powerful
component, Encrypt PDF SDK-COM allows you to encrypt
(using standard 40-bit or 128-bit supported by Acrobat
Reader 5.0 and up) existing PDFs, set permissions, add
user and owner password. For example you can encrypt a
PDF without to allow to print it. The button to print
the file will be disabled in Acrobat Reader
application, you also can encrypt a PDF allowing the
user to read it only if he know the correct password.
Note, The source PDF must be an unencrypted PDF.
Acrobat Reader will show a key in the bottom status
bar if the PDF is encrypted.
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).
