Security
Security profiles store your security settings, are re-useable, and help you work more quickly. Instead of re-entering passwords or re-adding recipient names every time you use document security, open the PDF file in Nitro Pro and select the security profile from a list. If you use certificate-based security and regularly send files to the same people, security profiles save you a lot of time.

Metadata is supporting information about the PDF document. It can describe properties such as authors, document creation date, reference numbers, information about embedded images, and so on.
Security
Redaction permanently removes parts of text or images from a PDF file, and replaces them with black rectangles. This lets you remove sensitive information from a paragraph, table, heading, or a bitmap image. The rest of the document is unaffected, and can be viewed and printed normally.
Security
The usage permission settings let you restrict what features can be used when a recipient opens a file you have secured. This means, for example, that you can distribute documents that can’t be edited or printed, but can be opened and viewed. Using these permission settings with digital ID certificate-based security gives you even greater flexibility as you can set different permissions for each individual recipient of your file.

The document information fields in Nitro Pro are useful for users who want to know more about a document, and they’re particularly useful if documents are to be indexed. These fields can be used to help categorize documents and help narrow down search results from search engines and other indexes.

Details on the security and restrictions that have been placed on a PDF can be found in the Document Properties dialog. For more information on various PDF permissions settings, refer to Permission settings.

With Nitro Pro you can edit the document title, author, subject, and keyword fields, as well as add your own custom metadata fields.
Security
Digital IDs let you encrypt files that can only be opened and used by people who have exchanged certificates. Certificate-based security has many advantages over password-based security: documents can be opened without the need to remember passwords, Digital IDs cannot be shared or copied easily, the one document can contain different security settings for each recipient of a file. For example, you may grant one person editing and printing privileges, while another is limited to just viewing the file.
