A document can have an open password and an owner password. If the document has
both types of passwords, it can be opened with either one, but you can set or change the
restricted features only with the owner password.
Note:
If you forget a password, there is no way to recover it from the document. It’s a good
idea to store passwords in another secure location in case you forget them.
Acrobat uses the RC4 method of security from RSA Corporation to secure PDF documents.
To set security for a document:

In the Document Security dialog box, choose Acrobat Standard Security for the security
method.

In the Standard Security dialog box, set the security options, as described in
“Adding
security to Adobe PDF files” on page 65
.
To set security for a collection of documents:
1
Define a new batch processing sequence or edit an existing sequence, as described in
“Batch processing” on page 124
.
2
With the named sequence highlighted, click Edit Sequence.
3
In the Batch Edit dialog box, click Select Commands.
4
Select Security in the left pane of the Edit Sequence dialog box, and click Add.
5
With Security highlighted in the right pane, click Edit. In the Document Security dialog
box, choose Acrobat Standard Security for Document Secured With, and click Change
Settings. Define the security parameters, as described in
“Adding security to Adobe PDF
files” on page 65
. Click OK to exit the definition process. You can review the security
parameters by clicking the triangle to the left of the sequence name. Click OK to return to
the Batch Edit Sequence dialog box.

the Batch Sequence dialog box.

Indexing document collections
Adobe recommends using Catalog to index document collections distributed on a CD.
Indexing builds a searchable database of all text in the documents in alphabetical order.
Users who have Acrobat on their system can use the Search command to quickly find
specific text in the index. See
“Defining and building an index” on page 224
for details on
building an index.
