About Redacted Text
Analyzer supports redacted text, which is text that is "blacked out" in Adobe PDF, Microsoft XPS, or XHTML Book output. This is much more efficient than attempting to black out text or other content after the document has been printed.
Redaction occurs when content is permanently eliminated from a printed or electronic document. In place of that content, end users will see black rectangles that indicate where the original content was found.
At each place in a document where you need to perform redaction, you can select the necessary content and apply the redaction.

Example
Let's say you are generating a sensitive legal document, and the names of individuals and other personal information need to be hidden. In that case, you can perform redaction for those areas so that they are blacked out when you build the output.
Here is what a topic with redacted text might look like in the output:

Redaction is useful for distributing or selectively releasing classified, sensitive, or private information. You might want to redact your output so that hackers cannot extract certain information in it that needs to remain hidden.
The consequences of failing to completely redact text in a document can range from the inadvertent release of sensitive information to legal liability, unwanted media exposure, or in the worst case, material harm to property or personnel.

You can set redacted text on any kind of content (e.g., characters, paragraphs, images, tables). You can do this locally at the font level by highlighting each piece of content.

Whereas condition tags allow you to remove text from output, redacting text lets you black out the necessary information but show that the original document once contained that information. If necessary, you could retrieve the redacted content. This may be important for legal purposes.

Important: When you use this feature, the text in the generated output is truly gone. There is no way a user can peek into the output and find it.
