Re: PDF security

I'm not sure if PDF has built in encryption, and if so, you should use that.  
If not, you have two options:

If the file exists only on your hard drive, then you should use your 
operating system's security to disable accesss to the file.  Windows 9x users 
right-click on the file, go to properties, and choose "read only", other 
Windows users modify the access control lists.

You can use a third-party encryption, such as PGP, to encrypt the file and 
make it so only users that have the correct key can see it.

I'm not sure how either of these solutions could be used directly within XSL, 
it seems like they have to be done as an extra step.  Someone please correct 
me if PDF does indeed have built-in access control.
