This class defines the encryption properties to be used while creating a pdf document.
Once initiated, a StandardEncryption object can be applied to a Canvas or a BaseDocTemplate.
The userPassword parameter sets the user password on the encrypted pdf.
The ownerPassword parameter sets the owner password on the encrypted pdf.
The boolean flags canPrint, canModify, canCopy, canAnnotate determine wether a user can
perform the corresponding actions on the pdf when only a user password has been supplied.
If the user supplies the owner password while opening the pdf, all actions can be performed regardless
of the flags.
Note that the security provided by these encryption settings (and even more so for the flags) is very weak.

PdfEncrypt encrypts your PDF files.
Line mode usage:
% pdfencrypt.exe pdffile [-o ownerpassword] | [owner ownerpassword],
[-u userpassword] | [user userpassword],
[-p 1|0] | [printable 1|0],
[-m 1|0] | [modifiable 1|0],

[-a 1|0] | [annotatable 1|0],
[-s savefilename] | [savefile savefilename],
[-v 1|0] | [verbose 1|0],
[-e128], [encrypt128],
[-h] | [help]
-o or owner set the owner password.
-u or user set the user password.
-p or printable set the printable attribute (must be 1 or 0).
-m or modifiable sets the modifiable attribute (must be 1 or 0).
-c or copypastable sets the copypastable attribute (must be 1 or 0).
-a or annotatable sets the annotatable attribute (must be 1 or 0).
-s or savefile sets the name for the output PDF file
-v or verbose prints useful output to the screen.
(this defaults to 'pdffile_encrypted.pdf').
'-e128' or 'encrypt128' allows you to use 128 bit encryption (in beta).
'-e256' or 'encrypt256' allows you to use 256 bit encryption (in beta AES).
-h or help prints this message.
