Adding security to PDF files
When saving as PDF, you can add password protection and security restrictions, limiting not only who can open the
file, but also who can copy or extract contents, print the document, and more.
A PDF file can require passwords to open a document (document open password) and to change security settings
(permissions password). If you set any security restrictions in your file, you should set both passwords; otherwise,
anyone who opens the file could remove the restrictions. If a file is opened with a permissions password, the security
restrictions are temporarily disabled.
The RC4 method of security from RSA Corporation is used to password-protect PDF files. Depending on the
Compatibility setting (in the General category), the encryption level will be high or low.
Note: Adobe PDF presets don't support passwords and security settings. If you select passwords and security settings in
the Export Adobe PDF dialog box, and then click Save Preset, the passwords and security settings won't be preserved.
Save an Adobe PDF preset
Although the default PDF presets are based on best practices, you may discover that your workflow requires
specialized PDF settings that aren't available using any of the built-in presets. In this case, you can create and save
your own custom presets for reuse in Photoshop or any product in the Adobe Creative Suite.
