Can Original Documents Be Uploaded After Changes On E-sign Program

The Adobe Acrobat Sign Digital Signature workflow is bachelor to all levels of service

Feature description

Digital Signatures are a type of Electronic Signature that uses a certificate-based Digital ID, obtained either from a deject-based trust service provider or from the signer's local system.

A digital signature, like a conventional handwritten signature, identifies the person signing a certificate. Unlike a handwritten signature, a document-based signature is difficult to forge because it contains encrypted information that is unique to the signer. It can be hands verified and informs recipients whether the certificate was modified after the signer initially signed the document.

Adobe Acrobat Sign supports digital signatures by simply placing the Digital Signature field on a course (either via Text Tags, elevate and drop in the Acrobat Sign Authoring surroundings or authoring in Adobe Acrobat with Acroforms).

Time Stamps

Fourth dimension stamps are a critical component of both the US and EU signature compliance standards when applying digital signatures.

The fourth dimension stamp acts as a locking machinery for both the signer's identity and the document itself.  Identity can be established in a number of ways (certificate, logon, id carte …) but the time postage has to exist provided by a trusted and authorized time stamping authority (TSA).

The time stamp guarantees the Long-Term Validity (LTV) of the signed agreement by locking the signature too every bit the document.  Essentially providing a lock for the lock.  This is disquisitional for digital signature compliance because personal signing certificates can expire, while the time stamp LTV can exist renewed over time without changing the validity of the signature.  The LTV time stamp assures the document was valid when applied and extends the validity of the signed agreement beyond the time scope of the signer'southward actual certificate.

Qualified Timestamp for due east-IDAS compliance in the Eu

All accounts on the Acrobat Sign EU1 instance in Europe accept eastward-IDAS compliant Qualified Timestamps existence applied past default. (Know what instance you are on)

How it'southward used

For Senders

From the Senders perspective, all that is required is for a Digital Signature field to exist placed on the document that is existence sent.

Each recipient can have, at most, one digital signature field assigned to them within an agreement. Any additional signature fields that are needed can be of the standard east-signature field type.

Note that just considering ane signer is using a digital signature does not mean that any other signers are required to. It'south perfectly allowable to have simply your internal signers apply digital signatures while external signers use the due east-signature field type (or vice versa).

Using Elevate and Drop Authoring

Template creators will find the Digital Signaturefield in theSignature Fieldssection of the Authoring environment.

Below you can see the e-signature field on the left, and the digital signature field on the right.

Text Tag Syntax

The syntax for a digital signature field uses the statement :digitalsignature

For example: {{digsig1_es_:signer1:digitalsignature}}

Equally previously stated, there can only be one digital signature field per signer in each certificate.

If you add more than one Digital Signature for a signer (due east.g.,{{digsig1_:signer1: digitalsignature}} and {{digsig2_:signer1: digitalsignature}}), merely the kickoff is preserved and the others are automatically removed when the document is sent for signature.

Building forms in Acrobat

Like all other field types, y'all can replicate the functionality of a Text Tag when edifice your documents in Acrobat by renaming the field to contain the full text tag with all arguments (just not the caryatid pairs on either terminate).

The Signer'south feel

Because digital signatures are document-based, signers demand to obtain a Digital ID before they tin apply their signature. This Digital ID can be obtained from i of several deject signature providers, or past applying the signature using Adobe Acrobat or Acrobat Reader, using a local Digital ID.

The Acrobat Sign solution walks the signer through the process:

• Open up the agreement, and fill in any required fields
• Choose from existing Digital IDs, or create a new one
  
• Apply the signature

Once the signature is applied, the signature wheel continues equally normal.

Open the understanding and fill in the fields...

Signers are notified via email, and instructed to open the agreement past clicking the Review and sign button

In one case the certificate is open, the signer tin can read the document and make full in whatsoever fields that are needed. All required fields need to be completed earlier the signer can advance the signature process.

Mousing over the digital signature field prompts a text balloon with additional instructions.

Clicking the field opens an overlay asking the signer to select one of two paths:

• Cloud Signature (the instructions below follow this path)
• Download and Sign With Acrobat (Click here to jump to the download instructions)

Select the appropriate option and click Adjacent

A new overlay is presented, asking the signer to select an identity provider from a drib-downwardly.

• Merely providers listed in the drop-down tin can be used
• Signers that practice not accept a permissible Digital ID can click the Click to go a new Digital ID link, and be routed to obtain a new Digital ID from ane of several cloud signature providers.
• One time they take established a new Digital ID, they can return to the signature process.

The identity provider challenges the signer to authenticate to their service

Once successfully authenticated, the signer is presented with a list of valid Digital IDs to choose from.

• Select the Digital ID
• Click Next

A preview of the signature is presented.

• ClickEdit Signatureto:
  • Manually sign via mouse or touch pad
  • Upload a signature prototype
• Click OK when ready to continue

The signer is returned to the agreement and prompted to Click to Sign

The identity provider and so may crave an boosted, second-cistron hallmark.

eg: The below provider requires a static PIN, established when setting upward the Digital ID, and a i-time password.

• Enter any required values, and click OK

When the second-cistron authentication is successfully entered, the certificate is signed, and a success bulletin is displayed.

Digital signatures practical via the "Download and Sign with Acrobat" option must utilize Adobe Acrobat or Adobe Acrobat Reader XI v11.0.7 or later on

After selectingDownload and Sign With Acrobat, an overlay is prompted describing the process

• Click OK

The blue Continue to Sign button pops upward from the bottom of the window when all required fields accept been filled.

• Click Go on to Sign

Download and open up the PDF in Acrobat or Adobe Reader

Clicking the Continue to Sign button launches the download page

If you practise not have Acrobat or Adobe Reader, you need to download and install it. At the bottom of the folio is a link (>Become it Here) to Adobe Reader, a free to utilise PDF viewer.

Click the Download Certificatebutton, and Acrobat (or Reader, depending on what application you take installed) opens the PDF.

At the acme of the Reader window is a blueish imprint indicating that a digital signature is needed.

A yellow tab indicates where to click and place the signature

Create a new Digital ID

Clicking the signature area opens a dialogue box showing any certificates available.

If valid Digital IDs are already present:

• Select one to utilise for your signature
• Click Continue
• Skip down to Apply the signature

If no certificate can be found, simply the buttons to Configure New Digital ID are available

After clicking the push to create a new Digital ID, you are presented with the configuration panel. Here you find three options:

• Employ a Signature Creation Device - Used when you have a physical device that yous connect to your local system.
• Utilize a Digital ID from a file - Used information technology import an existing Digital ID from a networked file
• Create a new Digital ID -Used when you practise not have an existing Digital ID that you tin can access

Select Create a new Digital ID and then click Continue

The console changes to ask where you want to store the Digital ID:

• Save to File - This option stores the Digital ID on your local organisation, and makes the Digital ID available for Adobe-based signatures
• Relieve to Windows Certified Store - Saving the Digital ID to the Windows Certified Store saves the Digital ID in a way that makes it available to applications other than Adobe Reader / Acrobat

Select Save to File, and click Continue

The console refreshes to bear witness the details of the Digital ID.

Brand sure that all fields are correctly filled in, and click Go along.

The next console asks you to provide a password for the Digital ID.

Y'all need to enter this countersign every time y'all attempt to apply your digital signature.

One time yous have entered your countersign, click Save to complete the creation of your Digital ID.

You are then returned to the beginning panel showing all of your Digital IDs.

Select the Digital ID to use, and click the Proceed button

Apply the signature

After clicking Continue, the panel refreshes to show the visual representation of your signature object.

You can use it as-is, or you lot can further customize the look of the object.

To customize it, click the Edit push at the peak right of the console, which loads the Customize panel.

At the summit of the Customize panel, notice that the same signature options exist as in the App.  You lot can opt to replace the default font with either a drawn signature, or an image.

Make any edits you like, and and so click Save to save the new format.

This returns yous to the previous screen, request for your Digital ID password.

Blazon the password for the chosen Digital ID into the field that says Enter the Digital ID PIN or Password and click Sign.

The Digital ID console disappears, and the PDF updates to show a new blue banner at the top, indicating that the signature is valid.  Additionally, a small-scale popular-upward window appears, confirming the successful digital signature.

Click OK and shut the PDF, the signature process for this recipient is complete!

Below is an example of a normal e-signature field on the left, and a digital signature on the right

History and Audit Report

The History tab, and the related Audit Report, are slightly different than a standard e-signature report in that they have an additional upshot: Document digitally signed

In the example below, yous can see that the first signer has one "eastward-signed" upshot, and that is all.

The second signer has both an e-signed consequence too as a digitally signed event.

The reason for this is the digital signature process takes place in 2 parts.  The function you lot do in the spider web browser (filling in the fields), and the part that y'all exercise on your local desktop (applying the digital signature certificate).

When the signer completes the field portion and clicks theSubmit and Keep to Signbutton, the input content is uploaded, and pressed into the PDF. This is what the eastward-signed consequence indicates.

When the digital signature is applied, the digitally signed event is posted.

Keeping in alignment with the History information, you can run into that the inspect report too reflects the two stages of the signature process.

How to configure

The Digital Signature workflow can exist enabled at the Account level by the Acrobat Sign Business relationship Admin.

• Group level settings are permitted and will override the Business relationship level values.

To access the Account level settings, navigate to: Account > Account Settings > Digital Signatures

There are several options that can exist configured to manage the signature experience:

Enable signers to import their digital signature from one or more sources:

• Download and Sign With Acrobat - Allows the signer to use a self-certified signature
• Cloud Signatures - Enables the choice to use a cloud-based digital signatures for your signers, which makes digital signing also possible on mobile devices
  • If digital signatures are of import to your signing process, enabling the cloud-based choice is strongly recommended.

Select the digital signature providers y'all will take.  Merely options selected will be bachelor to signers.

You tin define a preferred vendor, which sets that vendor as the default.

• If but one vendor is allowed, the selection process is bypassed during the signature procedure

Aadhaar signatures

Aadhaar signatures are available to enterprise accounts at an boosted per signature toll, which must be configured prior to utilize.

Customers that demand to obtain Aadhaar signatures can contact their Success Director or their Sales contact to talk over volume and start the configuration process.

External signers are defined equally any email address not within your Acrobat Sign business relationship.

• Internal signers existence all of the users defined within your Acrobat Sign business relationship

If yous would like to create a different signature feel for external signers vs internal, you can enable a second gear up of the in a higher place options that employ but to external signers.

For example, you may want to exist more permissive in the signature vendors for external signers, or provide different instructions for how to obtain a signature for internal signers.

Prove Signing Reason

Some compliance requirements demand that a reason for an applied digital signature be noted past the signer. eg: Title 21 CFR Part 11 and Condom-BioPharma compliance.

If digital signatures are being used to fulfill a compliance demand, consult with your legal team to make up one's mind if y'all should besides require a signature reason within the signature process.

To admission the controls, click the Bio-Pharma Settings link

If you demand advanced signature controls, refer to the BioPharma page >

Restricted Cloud Signature Providers

There are some providers that restrict the access to their service merely to pre-authorized customers. This means that the service volition not be accessible until the provider has authorized the account to use it.

BankID Sweden is a commercial service of such kind. Corporate-specific providers are besides restricted to authorized accounts.

During the activation process these providers volition crave the subscribing account to provide their "Account ID" to configure the service for them. Once authorized past the provider, your users will exist able to utilise the restricted service. Until so your users will typically run into an error message from the provider when trying to use a restricted service.

The Account ID is truly a belongings at the business relationship level. All groups from an business relationship share the same Business relationship ID, then once the restricted provider is authorized for an account, information technology becomes authorized for all groups of that account.

Digital Signature Format options

PKCS#7 is the default format governing the digital signature for most (non-EU) Acrobat Sign accounts.

Accounts on the European (EU1) shard use PAdES format (ETSI EN 319142) by default to encounter eIDAS compliance.

Whatsoever business relationship level admin can request to have this setting changed from one format to the other by sending a request to the Acrobat Sign Support squad.

This feature can be enabled and configured at the group or account level.

RSA-PSS

RSA-PSS is a signature scheme that is based on the RSA cryptosystem and provides increased security assurance relative to the older RSA-PKCS#ane v.1.v scheme.

The Acrobat Sign implementation of RSA-PSS does not require any configuration on the office of the Account Admin.

• When "Deject Signature" is called, and the signer's Digital ID supports both RSA-PSS and RSA-PKCS#1, the RSA-PSS signature scheme is used past default.
• When "Sign with Acrobat" is called, the use of RSS-PSS or RSA-PKCS#1 depends on the signer's settings in their Acrobat awarding
• Acrobat Sign fully supports CRL and OCSP responses that are signed with the RSA-PSS scheme.
• The employ of the RSA-PSS scheme is required to comply with Germany-specific requirements for Qualified Electronic Signatures.

Things to Know

The digital signature workflow forces the agreement into a unique procedure. Because of the special handling required to get the signature affixed, there are several limitations to exist enlightened of.

• Each signer can accept just i digital signature field assigned to them
• Web forms do not back up digital signatures
• Send in Bulk does not support Download and Sign With Acrobat signatures. Cloud-based digital signatures work every bit expected
• Digital Signatures disable Limited Document Visibility. All recipients volition see all pages
• Signers on Mobile devices can only apply a cloud-baseddigital signature
• Deject-based Digital ID using OAuth say-so style are not supported in Make full & Sign feature
• Fill up & Sign feature does not support signing with Aadhaar service provider.
• Users that are sharing their content, or accounts that accept advanced sharing enabled, cannot utilise digital signatures
• eVaulting cannot be used in conjunction with digital signatures
• File attachments can merely be applied by the first signer. Subsequent signers that attach new files invalidate all previous digital signatures
• Transaction Number fields volition catechumen a digital signature into an electronic signature
• The optional setting to Keep documents separated (when more than one is used to create the agreement) is not currently supported. The certificate can simply be returned as a single, complete file
