What is the difference between an e-signature and a digital signature in Acrobat Sign?

Feature E-signature Digital signature. Proof Level Limited proof of intent Strong proof, non-repudiation Technology Simple electronic mark PKI-backed security Legal Use Basic agreements High-stakes legal documents

How does Acrobat Sign ensure my signature is legally valid?

Acrobat Sign follows laws like the US ESIGN Act and EU eIDAS. This makes your e-signatures legally binding. It offers different signature levels, including Qualified Electronic Signatures (QES) for the highest legal standard. A detailed audit trail is created. This record proves the signature's authenticity in court. You can attach this audit trail to the signed PDF. This gives you court-ready evidence.

What information is included in an e-signature audit trail from Acrobat Sign?

IP address of the signer's device. Type of device used for signing. Timestamps for key actions during the signing process. Cryptographic hashes that ensure document integrity. A certificate of completion that summarizes the signing event.

Compliance needs countersignatures from finance, legal, and data security and will audit the trail next week. I’ve routed the packet but I don’t know which department still has it. I’ve done this before and fear a small missing signature will force a re‑execution. Diagnose the most likely hold‑up, tell me the exact proof I should request from each department now, and how to present the final audit bundle so it passes review without follow‑ups.

when the reply comes backPush once: ask it to sharpen the weakest part, and to say what it assumed.

How to do it

the tool · the steps · what to avoid

1
Sign up for an Adobe Developer account and create a new project in the Adobe Developer Console.
Best practiceUse a dedicated service account for automation to simplify credential management.
2
Add the Acrobat Services API to your project and generate OAuth credentials (Client ID and Secret).
3
Install the official Adobe PDF Services SDK for your programming language (e.g., npm install @adobe/pdfservices-node-sdk for Node.js).
4
Write code to authenticate using your Client ID and Secret to obtain an access token.
5
Use the PDF Services API’s Redaction API endpoint to programmatically redact sensitive information from PDFs.
NoteRedaction patterns can be defined using regular expressions or text strings.
6
Use the PDF Services API’s PDF/A Conversion endpoint to convert documents to PDF/A format for archival compliance.
CautionVerify that the output PDF/A meets your specific regulatory requirements.
7
Automate batch processing by looping over your PDF files and applying the redaction and PDF/A conversion endpoints as needed.
Best practiceFor large-scale jobs, implement retry logic and monitor API rate limits to avoid interruptions.
8
Store or route the processed, compliant PDFs to your document management system or cloud storage.

You can attach this audit trail to the signed PDF. This gives you court-ready evidence.

An audit trail is very important because it creates a clear record of the signing process. It includes details like the signer's IP address, device, timestamps, and cryptographic hashes. This information acts as court-ready evidence, proving who signed the document and that it has not been changed since signing. Without it, proving the signature's validity in a legal dispute would be difficult.

If you are in the EU and need a signature that is legally the same as a handwritten ('wet') signature, you should use a Qualified Electronic Signature (QES). The eIDAS regulation defines QES as having this highest legal equivalence. Acrobat Sign supports QES for such needs.
