ADOBE ACROBAT 3D VERSION 8 285 User Guide Verify signatures in the Signatures panel. Display the Signatures panel ❖ Choose View > Navigation Panels > Signatures, or click the Signatures button in the navigation pane. You can right-click/Control-click a signature field in the Signatures panel to do most signature-related tasks, including adding, clearing, and validating signatures. In some cases, however, the signature field may become locked after you sign it. Expand or collapse a signature ❖ In the Signatures panel, click the plus sign (Windows) or triangle (Mac OS) next to the signature to expand it. Click the minus sign (Windows) or the rotated triangle (Mac OS) to collapse it. When collapsed, the signature shows only the name, date, and status. Validate a timestamp certificate If a signature displays the date and time, that time is the local time on the signer's computer. However, a second date and time may appear in the Signature Properties dialog box, indicating that the signer uses a timestamp server. To validate a signature that contains a timestamp, you must obtain the certificate for the timestamp server and add it to your list of trusted identities. Otherwise, the timestamp appears in the Signatures panel as unverified, and you must validate the timestamp manually. 1 Click the Signatures button in the navigation pane, select the signature, and choose Validate Signature from the Options menu. 2 Click the Signature Properties button in the Signature Validation Status dialog box. 3 In the Signature Properties dialog box, click the Date/Time tab to view the timestamp authority, and then click the Show Certificate button. (This button appears in the Date/Time tab only if the signer used a timestamp server.) 4 In the Certificate Viewer, click the Trust tab to determine if the timestamp certificate is trusted. If it isn't trusted, click Add To Trusted Identities. If a certificate for the timestamp server isn't listed, request one from the signer. See also "Sharing and managing certificates" on page 258

ADOBE ACROBAT 3D VERSION 8

User Guide

Verify signatures in the Signatures panel.

Display the Signatures panel

❖

Choose View > Navigation Panels > Signatures, or click the Signatures button

in the navigation pane.

You can right-click/Control-click a signature field in the Signatures panel to do most signature-related tasks,

including adding, clearing, and validating signatures. In some cases, however, the signature field may become locked

after you sign it.

Expand or collapse a signature

❖

In the Signatures panel, click the plus sign (Windows) or triangle (Mac OS) next to the signature to expand it.

Click the minus sign (Windows) or the rotated triangle (Mac OS) to collapse it.

When collapsed, the signature shows only the name, date, and status.

Validate a timestamp certificate

If a signature displays the date and time, that time is the local time on the signer’s computer. However, a second date

and time may appear in the Signature Properties dialog box, indicating that the signer uses a timestamp server. To

validate a signature that contains a timestamp, you must obtain the certificate for the timestamp server and add it to

your list of trusted identities. Otherwise, the timestamp appears in the Signatures panel as unverified, and you must

validate the timestamp manually.

Click the Signatures button

in the navigation pane, select the signature, and choose Validate Signature from

the Options menu.

Click the Signature Properties button in the Signature Validation Status dialog box.

In the Signature Properties dialog box, click the Date/Time tab to view the timestamp authority, and then click

the Show Certificate button. (This button appears in the Date/Time tab only if the signer used a timestamp server.)

In the Certificate Viewer, click the Trust tab to determine if the timestamp certificate is trusted. If it isn’t trusted,

click Add To Trusted Identities. If a certificate for the timestamp server isn’t listed, request one from the signer.
