5.1.2 Creating Password Security for One-Time Use

Use this method if you:
Need to make the document backward-compatible to Acrobat 3.0.

Do not need to save the settings as a policy.

To apply password security to the current document:
1. Choose Advanced > Security > Show Security Properties.
2. Select Password Security from the Security Method menu.
3. Check or uncheck Save passwords with the policy.
4. Choose OK.
5. Set the compatibility level to control what encryption options will be available. Compatibility with
earlier versions of Acrobat may require encrypting all document contents. Compatibility levels include:
Acrobat 3.0 and later: All document contents are encrypted with the 40-bit RC4 algorithm. This

option provides the most limited set of permission setting options.
Acrobat 5.0 and later: Encryption uses the 128-bit RC4 encryption algorithm. This setting allows

the accessibility option to be selected independently of the copy option, restricts printing to 150-bit
dpi, and expands the set of Changes Allowed options.
Acrobat 6.0 and later: Encryption uses the 128-bit RC4 algorithm. This setting allows the option of

leaving the document metadata unencrypted while the remainder of the document is encrypted.
All of the options for Acrobat 5.0 and later are also available.
Acrobat 7.0 and later: Encryption uses the 128-bit AES algorithm. When selected, the option of

only encrypting the file attachments is available as well as all of the previous options.
Acrobat 9.0 and later: Encryption uses the 256-bit AES algorithm. When selected, the option of

only encrypting the file attachments is available as well as all of the previous options.
6. Configure the Select Document Components to Encrypt panel:
All contents: Encrypts the document and its metadata (Acrobat 3 and later).

All contents except metadata: Allows for document storage/retrieval systems and search engines

to have access to the document metadata. A document open or a permissions password will
required to access other document content.
Encrypting everything except the metadata allows continued access to Acrobat's Catalog feature.
By leaving the metadata unencrypted, users can catalog and index the metadata of encrypted
documents, thereby making that data searchable (compatible with Acrobat 6 and later).
Only file attachments: Allows full access to the document and encrypts only the file attachments.

Permissions cannot be set on attachments. Using password security, a document open password is
required for attachments (compatible Acrobat 7 and later).
