# Opening a Protected Document

You can open a protected document using the following methods:

- Opening a document protected by a password
- Opening a document protected by an Electronic Signature
- Opening a document protected by a Digital Certificate

## Opening a document protected by a password

Procedure
1.
Open a document protected by a password. The procedure is the same as the procedure for opening an unprotected document.
The [Password] dialog box appears.
2.
Enter the password to open the document in [Open password]. Specify whether to temporarily store the open password, then click [OK].
Viewer opens displaying the contents of the protected document.
If you have selected [Store this password temporarily], DWSPswd starts and a corresponding icon appears in the notification area on the right side of the task bar.
Note
If the open password is not specified for the protected document or if its open password is temporarily stored, the protected document opens without requiring you to enter the password.

## Opening a document protected by an Electronic Signature

To open a document protected by Electronic Signature, you must prepare an Electronic Signature and an Electronic Signature Case as follows:

- The Electronic Signature capable of opening the protected document must be placed in the [My Signature] tab of your Electronic Signature Case.
- The Electronic Signature Case mentioned above must be open.

If the Electronic Signature Case is not open when you try to open a protected document, the Electronic Signature Case Tool automatically starts and asks you to enter the password. Enter the appropriate password to open the Electronic Signature Case.
Note
Documents protected by Electronic Signatures cannot be opened in Viewer Light unless DocuWorks is installed.

## Opening a document protected by a Digital Certificate

To open a document protected by a Digital Certificate, the certificate that was used to configure the security must be registered with [Personal] in the Windows Certificate Manager.
