Set your verification preferences in advance. This helps ensure that Digital Signatures are valid when you open a PDF and verification details appear with the signature. Meet Ready signature verification preferences for details.

When Digital Signatures are validated, an icon appears in the document message bar to indicate the signature status. Boosted status details appear in the Signatures panel and in the Signature Backdrop dialog box.

Setting up digital signature validation

When you receive a signed document, you may want to validate its signature(due south) to verify the signer and the signed content. Depending on how you accept configured your application, validation may occur automatically. Signature validity is determined by checking the authenticity of the signature'southward digital ID certificate status and document integrity:

  • Authenticity verification confirms that the signer's document or its parent certificates exist in the validator's list of trusted identities. Information technology also confirms whether the signing certificate is valid based on the user'south Acrobat or Reader configuration.

  • Document integrity verification confirms whether the signed content changed later on it was signed. If content changes, document integrity verification confirms whether the content changed in a manner permitted by the signer.

Set up signature verification preferences

  1. Open up the Preferences dialog box.

  2. Under Categories, select Signatures.

  3. For Verification, click More.

  4. To automatically validate all signatures in a PDF when y'all open the document, select Verify Signatures When The Document Is Opened. This pick is selected by default.

  5. Select verification options as needed and click OK.

    Verification Behavior

    When Verifying

    These options specify methods that make up one's mind which plug-in to choose when verifying a signature. The appropriate plug-in is often selected automatically. Contact your system administrator nigh specific plug-in requirements for validating signatures.

    Require Certificate Revocation Checking To Succeed Whenever Possible ...

    Checks certificates confronting a list of excluded certificates during validation. This option is selected by default. If you deselect this option, the revocation condition for approval signatures is ignored. The revocation condition is always checked for certifying signatures.

    Use Expired Timestamps

    Uses the secure time provided by the timestamp or embedded in the signature, even if the signature's document has expired. This option is selected by default. Deselecting this option allows discarding of expired timestamps.

    Verification Time

    Verify Signatures Using

    Select an selection to specify how to check the digital signature for validity. By default, you lot can check the time based on when the signature was created. Alternatively, check based on the current time or the time fix past a timestamp server when the document was signed.

    Verification Data

    Specifies whether to add together verification information to the signed PDF. Default is to warning user when verification data is also big.

    Windows Integration

    Trust All root certificates in the Windows Certificate Store for

    Specify whether to trust all root certificates in the Windows Certificates Store for:

    • Validating signatures: Certificates are trusted for approval signature validation.
    • Validating certified documents: Certificates are trusted for certification signature validation.

    Selecting these options tin can compromise security.

    It is not recommended to trust all root certificates in the Windows Certificate Store. Many certificates that are distributed with Windows are designed for purposes other than establishing trusted identities.

Prepare the trust level of a document

In Acrobat or Reader, the signature of a certified or signed document is valid if y'all and the signer have a trust human relationship. The trust level of the certificate indicates the actions for which you trust the signer.

You can alter the trust settings of certificates to allow specific actions. For example, y'all can change the settings to enable the dynamic content and embedded JavaScript within the certified document.

  1. Open the Preferences dialog box.

  2. Under Categories, select Signatures.

  3. For Identities & Trusted Certificates, click More.

  4. Select Trusted Certificates on the left.

  5. Select a certificate from the listing, and click Edit Trust.

  6. In the Trust tab, select whatever of the following items to trust this certificate:

    Apply This Certificate As A Trusted Root

    A root certificate is the originating potency in a chain of certificate government that issued the certificate. By trusting the root certificate, you trust all certificates issued by that certificate authority.

    Signed Documents Or Information

    Acknowledges the identity of the signer.

    Certified Documents

    Trusts documents in which the author has certified the certificate with a signature. Yous trust the signer for certifying documents, and you accept actions that the certified document takes.

    When this option is selected, the following options are available:

    Dynamic content

    Allows movies, sound, and other dynamic elements to play in a certified document.

    Embedded High Privilege JavaScript

    Allows privileged JavaScript embedded in PDF files to run. JavaScript files can exist used in malicious ways. It is prudent to select this option but when necessary on certificates you trust.

    Privileged System Operations

    Allows Net connections, cantankerous domain scripting, silent press, external-object references, and import/export methodology operations on certified documents.

    Only allow Embedded High Privilege JavaScript and Privileged System Operations for sources you trust and work with closely. For case, use these options for your employer or service provider.

  7. Click OK, close the Digital ID and Trusted Certificate Settings dialog box, and then click OK in the Preferences dialog box.

For more than information, see the Digital Signature Guide at www.adobe.com/become/acrodigsig.

Signatures panel for digital signatures

The Signatures panel displays information almost each digital signature in the current certificate and the modify history of the document since the showtime digital signature. Each digital signature has an icon identifying its verification status. Verification details are listed beneath each signature and can exist viewed by expanding the signature. The Signatures panel also provides information about the time the document was signed, and trust and signer details.

Signatures panel in Acrobat

Verify signatures in the Signatures panel

  1. Choose View > Evidence/Hide > Navigation Panes > Signatures, or click the Signature Panel button in the certificate message bar.

You tin can correct-click a signature field in the Signatures panel to do almost signature-related tasks, including adding, clearing, and validating signatures. In some cases, nevertheless, the signature field becomes locked afterward yous sign it.

Sign in Preview Document style

When document integrity is critical for your signature workflow, use the Preview Document feature to sign documents. This feature analyzes the certificate for content that may modify the appearance of the document. It then suppresses that content, allowing you to view and sign the document in a static and secure state.

The Preview Document feature lets you find out if the certificate contains any dynamic content or external dependencies. It as well lets you find out if the certificate contains any constructs such as form fields, multimedia, or JavaScript that could affect its appearance. Afterward reviewing the report, y'all can contact the author of the document near the problems listed in the report.

  1. Open the Preferences dialog box.

  2. Nether Categories, select Signatures.

  3. For Creation & Appearance, click More than.

  4. For When Signing, select View Documents In Preview Mode, and click OK.

  5. In the PDF, click the signature field and choose Sign Document.

    The certificate message bar appears with the compliance status and options.

  6. (Optional) Click View Report in the document message bar (if bachelor) and select each item in the list to show details. When you're done, close the PDF Signature Written report dialog box.

  7. If you're satisfied with the compliance status of the document, click Sign Document in the document message bar, and add your digital signature.

  8. Save the PDF using a unlike name than the original, and shut the document without making whatsoever further changes.

Certify a PDF

When yous certify a PDF, you lot indicate that you approve of its contents. You also specify the types of changes that are permitted for the document to remain certified. For example, suppose that a government agency creates a form with signature fields. When the course is complete, the agency certifies the document, allowing users to change only form fields and sign the document. Users can fill the form and sign the document. All the same, if they remove pages or add comments, the certificate doesn't retain its certified status.

You can apply a certifying signature only if the PDF doesn't already contain any other signatures. Certifying signatures tin be visible or invisible. A blue ribbon icon in the Signatures console indicates a valid certifying signature. A digital ID is required to add the certifying digital signature.

  1. Remove content that may compromise certificate security, such every bit JavaScripts, actions, or embedded media.

  2. Choose Tools > Certificates to open up the panel.

  3. Click one of the post-obit options:

    Certify (Visible Signature)

    Places a certified signature in either an exiting digital signature field (if available) or in the location you designate.

    Certify (Invisible Signature)

    Certifies the document, but your signature appears merely in the Signatures panel.

  4. Follow the onscreen instructions to place the signature (if applicative), specify a digital ID, and set up an option for Permitted Actions After Certifying.

    If you enabled the When Signing: View Documents In Preview Mode in the Signature preferences, click Sign Document in the certificate message bar.

  5. Save the PDF using a unlike filename than the original file, and then close the document without making additional changes. It is a good idea to save it equally a dissimilar file so that you tin can retain the original unsigned document.

Timestamp a certificate

Acrobat provides users with the adequacy to add a document timestamp to a PDF without too requiring an identity-based signature. A timestamp server is required to timestamp a PDF. (See Configure a timestamp server.) A timestamp assures the authenticity and existence of a document at a particular time. These timestamps are compliant with the timestamp and revocation features described in Part 4 of ETSI 102 778 PDF Advanced Electronic Signatures (PAdES) standard. Users of Reader X (and afterwards) tin can also timestamp a certificate if the document includes advisable Reader Enabling features.

For more data on PAdES, come across blogs.adobe.com/security/2009/09/eliminating_the_penone_step_at.html.

  1. Open the document to which you want to add a timestamp.

  2. Choose Tools > Certificates > Time Postage .

  3. In the Choose Default Timestamp Server dialog box, select a default timestamp server from the listing, or add a new default timestamp server.

  4. Click Next, and then save the document with the timestamp.

Validate a digital signature

If the signature status is unknown or unverified, validate the signature manually to make up one's mind the problem and possible solution. If the signature condition is invalid, contact the signer about the problem.

For more than information nearly signature warnings and valid and invalid signatures, see the Digital Signature Guide at www.adobe.com/go/acrodigsig.

Y'all assess the validity of a Digital Signature and Timestamp by checking the Signature Backdrop.

  1. Open the PDF containing the signature, so click the signature. The Signature Validation Condition dialog box describes the validity of the signature.

  2. For more than information about the Signature and Timestamp, click Signature Properties.

  3. Review the Validity Summary in the Signature Properties dialog box. The summary might display one of the following messages:

    Signature date/time are from the clock on the signer'south computer

    The time is based on the local fourth dimension on the signer'southward computer.

    Signature is timestamped

    The signer used a Timestamp Server and your settings bespeak that you have a trust relationship with that timestamp server.

    Signature is timestamped only the timestamp could not exist verified

    Timestamp verification requires obtaining the timestamp server's certificate to your list of trusted identities. Check with your organisation administrator.

    Signature is timestamped just the timestamp has expired

    Acrobat and Reader validate a timestamp based on the electric current time. This bulletin is displayed if the timestamp signer'due south certificate expires before the current time. To let Acrobat or Reader accept an expired timestamp, select Apply Expired Timestamps in the Signature Verification Preferences dialog box (Preferences > Signatures > Verification: More). Acrobat and Reader display an warning message when validating signatures with expired timestamp.

  4. For details about the signer's certificate, such as trust settings or legal restrictions of the signature, click Evidence Signer'southward Document in the Signature Properties dialog box.

    If the certificate was modified afterwards information technology was signed, check the signed version of the document and compare it to the current version.

Remove a digital signature

You cannot remove a digital signature unless you are the one who placed information technology and you take the digital ID for signing it installed.

  1. Practice one of the following:

    • To remove a digital signature, right-click the signature field and choose Clear Signature.
    • To remove all digital signatures in a PDF, choose Clear All Signature Fields from the options menu in the Signatures panel. (To open the Signatures panel, choose View > Show/Hide > Navigation Panes > Signatures.)

View previous versions of a digitally signed certificate

Each fourth dimension a document is signed using a document, a signed version of the PDF at that fourth dimension is saved with the PDF. Each version is saved as suspend-only and the original cannot exist modified. All digital signatures and their corresponding versions can be accessed from the Signatures panel.

  1. In the Signatures panel, select and expand the signature, and choose View Signed Version from the Option menu .

    The previous version opens in a new PDF, with the version information and the name of the signer in the championship bar.

  2. To return to the original document, choose the document name from the Window carte.

Compare versions of a signed document

After a document is signed, you can display a list of the changes fabricated to the certificate after the last version.

  1. In the Signatures console, select the signature.

  2. Choose Compare Signed Version To Electric current Version from the Selection card .

  3. When you're done, close the temporary document.

Trust a signer'south 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 oft exchange certificates as needed when using certificate security. Alternatively, they add together certificates directly from signatures in signed documents and and then gear up trust levels. Nevertheless, enterprises oft require employees to validate the signatures of others without performing any manual chore. Acrobat trusts all certificates for signing and certifying that concatenation up to a trust anchor. Therefore, administrators should preconfigure client installations or let their stop users add together a trust anchor or anchors. For more information on trusting certificates, see Most certificate-based signatures.

Digital signatures that were added using a self-signed certificate cannot exist automatically validated by Adobe as the certificate is not in the list of Trusted Identities that Adobe uses to validate signatures. A self-signed certificate is a certificate that you have generated yourself using a third-party application. You lot won't exist able to manually validate the signature until the document is trusted past Adobe. If you open such a PDF, yous will run into a warning At least one signature has problems .

Signature validity warning message

For security reasons, Adobe does not recommend calculation a cocky-signed certificate, or any random certificate to the Adobe's list of Trusted Identities.

To add the certificate that was used to apply the digital signature into Adobe's list of Trusted Identities, do the post-obit:

  1. Click the Signatures button in the left-pane.

  2. Right-click the signature, and so click Evidence Signature Backdrop.

    Signature properties

  3. In the Signature Properties dialog box, click Show Signer's Document.

    Show Signer's certificate

  4. In the Certificate Viewer dialog box, click the Trust tab, and so click Add To Trusted Certificates.

    Add to trusted certificates

  5. Click OK in the trust settings popular-up dialog, and then click OK.

PDF Portfolios and digital signatures

You lot can sign component PDFs within a PDF Portfolio, or sign the PDF Portfolio equally a whole. Signing a component PDF locks the PDF for editing and secures its content. Subsequently signing all the component PDFs, you can sign the entire PDF Portfolio to finalize information technology. Alternatively, you can sign the PDF Portfolio as a whole to lock the content of all component PDFs simultaneously.

  • To sign a component PDF, run across Signing PDFs. 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 Canvas). Once you sign the PDF Portfolio as a whole, y'all cannot add together signatures to the component documents. Even so, yous can add together more than signatures to the cover sheet.

Digital signatures on attachments to component PDFs

Yous tin can add signatures to attachments before signing the comprehend sheet. To utilise signatures to fastened PDFs, open the PDF in a divide window. Correct-click the attachment, and choose Open File from the context bill of fare. To view signatures on the PDF Portfolio, navigate to the embrace 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. The most significant signature appears in a Signature Badge in the toolbar. Details of all signatures appear in the comprehend sheet.

Signature Badge in Acrobat

The Signature Bluecoat provides a quick way to verify the PDF Portfolio's approving or certification.

  • To view the proper noun of the organization or person that signed the PDF Portfolio, hover the arrow over the Signature Bluecoat.

  • To view details most the signature that appears in the Signature Badge, click the Signature Bluecoat. The embrace sail 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 arrow over a Signature Badge with a warning icon. Unlike warning icons appear for dissimilar situations.

For a list and explanation of each warning, see the DigSig Admin Guide at www.adobe.com/become/acrodigsig.

XML data signatures

Acrobat and Reader support XML data signatures that are used to sign data in XML Forms Architectures (XFA) forms. The course author provides XML signing, validating, or clearing instructions for grade events, such every bit button click, file save, or submit.

XML data signatures arrange to the W3C XML-Signature standard. Like PDF digital signatures, XML digital signatures ensure integrity, hallmark, and non-repudiation in documents.

However, PDF signatures accept multiple data verification states. Some states are called when a user alters the PDF-signed content. In dissimilarity, XML signatures only have ii data verification states, valid and invalid. The invalid state is called when a user alters the XML-signed content.

Constitute long-term signature validation

Long-term signature validation allows you to cheque the validity of a signature long later the certificate was signed. To achieve long-term validation, all the required elements for signature validation must be embedded in the signed PDF. Embedding these elements can occur when the document is signed, or after signature creation.

Without certain information added to the PDF, a signature tin be validated for merely a express fourth dimension. This limitation occurs because certificates related to the signature eventually elapse or are revoked. Once a certificate expires, the issuing authority is no longer responsible for providing revocation status on that certificate. Without conforming revocation condition, the signature cannot be validated.

The required elements for establishing the validity of a signature include the signing certificate chain, certificate revocation condition, and possibly a timestamp. If the required elements are available and embedded during signing, the signature can exist validated requiring external resources for validation. Acrobat and Reader tin embed the required elements, if the elements are available. The PDF creator must enable usage rights for Reader users (File > Salve Every bit Other > Reader Extended PDF).

Embedding timestamp information requires an accordingly configured timestamp server. In addition, the signature validation time must exist gear up to Secure Fourth dimension (Preferences > Security >Avant-garde Preferences > Verification tab). CDS certificates can add verification information, such equally revocation and timestamp into the document without requiring whatsoever configuration from the signer. Nonetheless, the signer must be online to fetch the appropriate information.

Add verification data at signing

  1. Make sure that your computer can connect to the appropriate network resources.

  2. Ensure that the preference Include Signature'southward Revocation Status is yet selected (Preferences > Signatures > Cosmos & Appearances: More). This preference is selected past default.

If all the elements of the certificate chain are available, the information is added to the PDF automatically. If a timestamp server has been configured, the timestamp is also added.

Add verification information subsequently signing

In some workflows, signature validation information is unavailable at signing, but can be obtained after. For example, a company official may sign a contract using a laptop while traveling by air. The computer cannot communicate with the Internet to obtain timestamping and revocation data to add to the signature. When Internet access is bachelor afterwards, anyone who validates the signature can add together this information to the PDF. All subsequent signature validations can also use this information.

  1. Ensure that your computer tin can connect to the appropriate network resources, and then right-click the signature in the PDF.

  2. Choose Add Verification Data.

Data and methods used to include this long term validation (LTV) information in the PDF comply with Part 4 of the ETSI 102 778 PDF Advanced Electronic Signatures (PAdES) standard. For more than data, see blogs.adobe.com/security/2009/09/eliminating_the_penone_step_at.html. The command is unavailable if the signature is invalid, or is signed with a self-signed certificate. The command is also unavailable in instance the verification time equals the electric current time.
