USING ACROBAT X STANDARD
Digital signatures
Last updated 10/11/2011
Trust a signer’s certificate
Trusting a certificate involves adding it to the user’s trusted identity list in the Trusted Identity Manager and manually
setting its trust level. End users often exchange certificates as needed when using certificate security. Alternatively, they
add certificates directly from signatures in signed documents and then set trust levels. However, enterprises often
require employees to validate the signatures of others without performing any manual task. Acrobat trusts all
certificates for signing and certifying that chain up to a trust anchor. Therefore, administrators should preconfigure
client installations or let their end users add a trust anchor or anchors. For more information on trusting certificates,
see
“About digital signatures” on page 222.
PDF Portfolios and digital signatures
You can sign component PDFs within a PDF Portfolio, or sign the PDF Portfolio as a whole. Signing a component PDF
locks the PDF for editing and secures its content. After signing all the component PDFs, you can sign the entire PDF
Portfolio to finalize it. Alternatively, you can sign the PDF Portfolio as a whole to lock the content of all component
PDFs simultaneously.
• To sign a component PDF, see “Signing PDFs” on page 229. The signed PDF is automatically saved to the PDF
Portfolio.
• To sign a PDF Portfolio as a whole, sign the cover sheet (View > Portfolio > Cover Sheet). Once you sign the PDF
Portfolio as a whole, you cannot add signatures to the component documents. However, you can add more
signatures to the cover sheet.
Digital signatures on attachments to component PDFs
You can add signatures to attachments before signing the cover sheet. To apply signatures to attached PDFs, open the
PDF in a separate window. Right-click the attachment, and choose Open File from the context menu. To view
signatures on the PDF Portfolio, navigate to the cover sheet to view the document message bar and signatures pane.
Signed and certified PDF Portfolios
A properly signed or certified PDF Portfolio has one or more signatures that approve or certify the PDF Portfolio. In
Acrobat X, the details of those signatures appear only in the cover sheet (View > Portfolio > Cover Sheet). In Acrobat
10.1 and later, the most significant signature appears in a Signature Badge in the toolbar. Details of all signatures
appear in the cover sheet.
The Signature Badge provides a quick way to verify the PDF Portfolio's approval or certification.
• To view the name of the organization or person that signed the PDF Portfolio, hover the pointer over the Signature
Badge.
• To view details about the signature that appears in the Signature Badge, click the Signature Badge. The cover sheet
and the Signatures pane on the left open with details.
If the PDF Portfolio approval or certification is invalid or has a problem, the Signature Badge shows a warning icon.
To view an explanation of the problem, hover the pointer over a Signature Badge with a warning icon. Different
warning icons appear for different situations.
For a list and explanation of each warning, see the DigSig Admin Guide at www.adobe.com/go/learn_acr_security_en.
