How Is a Digital Signature Created in signNow
Award-winning eSignature solution
What a digital signature is and how it works
A digital signature is a cryptographic way to sign an electronic document and prove who signed it and whether the file changed after signing. In practice, the signer’s document is hashed, then that hash is signed with a private key and verified with a public key. The result links the signer’s identity to the record and creates tamper evidence. In the U.S., this supports business contracts, approvals, and records that need reliable attribution, integrity, and an audit trail.
Why digital signatures matter legally
Digital signatures reduce paper handling, speed approvals, and create evidence of intent, identity, and document integrity. Under ESIGN and UETA, they can be legally enforceable when the signer consents and the record is retained properly.
Common digital signature pitfalls
Signer identity can be weak if the workflow relies only on email access or a shared inbox. Document changes after signing can break trust if tamper-evident controls and hash verification are missing. Poor consent capture can create disputes about whether the signer agreed to electronic delivery and signing. Missing audit details can make it harder to prove who signed, when they signed, and from which device.
Who uses digital signatures
Real estate
Real estate teams use digital signatures for leases, disclosures, and closing documents that move between agents, brokers, and clients.

People who benefit most
A director of NetSuite operations at Xerox uses signNow to route the right documents to the right people in the right format. That kind of workflow matters when approvals depend on system data, role-based routing, and a clean audit trail across finance or operations teams. A founder at Martin Properties uses signNow to execute documents online with built-in security and mobile access. That profile fits property teams that need fast lease and transaction turnaround without in-person meetings, while still keeping records organized for compliance and later review.
Core features and benefits
signNow supports digital signature workflows with controls that help teams sign, track, store, and verify documents more consistently.
Identity proof
Create a signing flow that records intent, identity, and document integrity in one process, making the final record easier to trust and review.
Audit trail
Capture signer actions in a detailed history so teams can confirm who viewed, signed, declined, or completed each document.
Templates
Use templates to standardize repeat documents, reduce setup time, and keep approval language consistent across teams and departments.
Mobile access
Support mobile signing so people can review and sign documents from phones or tablets without printing or scanning.
Signing order
Route documents in order when multiple people must sign, which helps preserve approval sequence and reduce confusion.
Tamper evidence
Store signed files with tamper-evident protection so later edits are easier to detect and document integrity stays clear.
How the signing process works
A digital signature workflow follows a short sequence from document delivery to final record sealing and verification.
Open document: The signer opens the document and reviews the request. Verify signer: The system verifies identity with the chosen method. Apply signature: The signature is applied and the file is hashed. Seal record: The completed record is sealed with an audit trail.

Real-world signing examples
These examples show how signNow fits operational and compliance needs across business teams that rely on signed records.
Operations workflow
A NetSuite operations leader needed document routing that matched internal systems and approval rules.
- Xerox used signNow with NetSuite integration.
- Right documents reached the right people.
The workflow reduced manual handoffs and kept approvals tied to the company’s existing business systems, which made document execution easier to track and manage.
Real estate execution
A property founder needed online execution for leases and related forms without losing control of the record.
- Martin Properties signed documents online.
- Mobile and offline signing supported field work.
The process supported faster turnaround for property documents while keeping the signing record organized, secure, and easier to review later.
Best practices for reliable signing
A careful setup improves attribution, record integrity, and long-term defensibility without adding unnecessary friction for signers.

FAQ and troubleshooting
These answers focus on plan features, compliance requirements, and setup issues that affect digital signature workflows in the U.S.
signNow Business includes audit trails, templates, mobile apps, and legally binding eSignatures. If you need HIPAA support, confirm a BAA and use the compliance settings that match your workflow.
signNow supports ESIGN and UETA-aligned workflows, but legal enforceability still depends on consent, attribution, and record retention. Keep the audit trail and signed file together for evidence.
For HIPAA workflows, signNow can be used with a BAA. The signed record should be retained for 6 years under 45 CFR 164.530(j)(2) when PHI is involved.
If a signer cannot access the document, check the invitation email, link expiration, and field permissions. signNow’s templates and signer routing help reduce setup errors before sending.
If you need bulk sending, that feature is included in Business Premium. Enterprise adds advanced signer authentication and formula fields, which can help with more controlled workflows.
For regulated records, use the audit trail and time-stamped history to support 21 CFR Part 11 or HIPAA documentation needs. The record should show who acted, when, and from where.
