Security Options For Adobe Pdf Files - Adobe GOLIVE CS2 User Manual

Security options for Adobe PDF files

When you export to PDF, you can set the following Security options:
Sets the type of encryption for opening a password-protected document. The Acrobat 4 (PDF 1.3)
Compatibility
option uses a low encryption level (40-bit RC4), while the other options use a high encryption level (128-bit RC4).
Acrobat 6 (PDF 1.5) or later lets you enable metadata for searching.
Be aware that anyone using an earlier version of Acrobat cannot open a PDF document with a higher compatibility
setting. For example, if you select Acrobat 7 (PDF 1.6) compatibility for a document's security setting, the document
cannot be opened in Acrobat 6.0 or earlier.
