Adding security to Adobe PDF files
You can limit access to all Adobe PDF files created by Distiller by giving the files passwords
and restricting certain features such as printing and editing.You can limit the access when
you first create a PDF file or any time you save the file in Acrobat.When files have restricted
features, any tools and menu items related to those features are dimmed.
A PDF file can have an open document password (user password) and a change security
settings password (master password). If the file has both passwords, it can be opened with
either one. When a file is opened with an open document password, the security restric-
tions are temporarily disabled. If you set any security restrictions in your file, you should
also specify a change security setting password (master password); otherwise anyone who
opens the file could remove the restrictions.
Acrobat uses the RC4 method of security from RSA Corporation to secure PDF files.
For information on encrypting PDF files, see
“Encrypting PDF files” on page 192
