Digital Signature and Encryption for SignNow
Award-winning eSignature solution
What digital signature and encryption means
Digital signature and encryption is a secure way to sign documents electronically while protecting the file from unauthorized changes. In practice, the signer’s identity is verified, the document content is hashed, and the signed file is sealed so later edits are detectable. For U.S. business use, this supports ESIGN and UETA evidence requirements, helps preserve audit trails, and gives organizations a defensible record for contracts, forms, and regulated workflows without relying on paper signatures.

How the process works
The signing flow moves from preparation to delivery, then captures identity, time, and integrity data before archiving the completed record.
Prepare: Create the document, add fields, and set the signer order before sending. Deliver: The signer receives a link and completes identity checks if required. Sign: The system captures the signature, timestamps, and document hash. Seal: The completed file is stored with its audit trail for later review.
Quick signing workflow
A short workflow helps teams send documents, collect signatures, and store the finished record without unnecessary steps.
Select a template:
Choose a template that matches the document type and route it to the right signer group. Set signer roles:
Add signer names, roles, and signing order before sending the document. Turn on reminders:
Enable reminders so pending signers get follow-up notices without manual tracking. Save the final record:
Review the completed file and export the signed PDF for storage.
Inside the audit trail
The audit trail records verification, timestamps, and document integrity steps that help show what happened from first view to final signature.

Key workflow features
These features support secure signing, cleaner recordkeeping, and flexible workflows for U.S. businesses that need electronic signatures and encryption.
Reusable templates
Create reusable templates for contracts, NDAs, and forms, then send them with consistent fields and signer order. That reduces setup time and keeps recurring workflows aligned across teams.
Audit evidence
Audit trails record signer actions, timestamps, and delivery history, giving teams a clear record for dispute review and compliance checks. The completed file can be stored with its evidence package.
Mobile access
Mobile signing supports review and completion on iOS and Android, which helps field teams and remote signers finish documents without returning to a desk.
Controlled routing
Plan controls support bulk send, delegated workflows, and advanced authentication options on higher tiers, which helps teams manage larger document volumes with clearer permissions.
Encrypted storage
Encryption in transit and at rest helps protect document content while it moves and after it is stored, supporting regulated workflows and private business records.
Connected systems
Integration options connect signing workflows with systems like Salesforce, NetSuite, Microsoft Dynamics 365, Google Workspace, and Box so records stay closer to the systems teams already use.
Who uses digital signature and encryption
Legal and client work
Contracts, NDAs, and consent forms help legal teams and client-facing groups finalize agreements with clear audit trails and signed records.
Business operations
HR forms, invoices, and onboarding packets help operations teams collect approvals quickly while keeping records organized for review.
Users, roles, and permissions
Operations managers in finance and banking use shared templates and delegated sending to route contracts, tax forms, and invoice approvals through controlled review steps. SignNow’s admin tools help standardize permissions and reduce manual handoffs across departments working under ESIGN and UETA requirements. HR and compliance coordinators use role-based access to send onboarding packets, policy acknowledgments, and consent forms. Shared templates keep documents consistent, while audit trails and plan-level controls support records that may need HIPAA, FERPA, or retention review.
Business types that benefit most
Different organizations use digital signature and encryption for different reasons, from mobile closings to regulated internal approvals.
A solo real estate practitioner can use SignNow to send leases, disclosures, and addenda from one dashboard, then track each signer without paper handoffs. The workflow is useful when deals move quickly and clients sign from mobile devices or from different locations. A regional healthcare group can use SignNow for intake packets, consent forms, and internal policy acknowledgments while keeping BAA-backed compliance in view. The ability to collect signatures across clinics and mobile devices helps staff avoid delays at check-in and discharge. An enterprise operations team can use SignNow for contracts, invoices, and approvals that need delegated sending, role-based access, and standardized templates. Centralized controls matter when many departments need consistent document routing and audit documentation for review.
These tasks are executed by both individual contributors and centralized administrators depending on organizational policy and required controls.

Ways to send and sign
- Use the web app when you need full document control, template management, and desktop review before sending contracts, HR forms, or approvals to multiple signers.
- Use the mobile app when signers need to review and sign on iOS or Android while traveling, visiting clients, or working away from a desk.
- Use kiosk mode for in-person signups, reception desks, and controlled check-in points where one device collects signatures from many people during routine intake.
- Use shareable signing links when recipients should open a document from email, chat, or a portal without complex onboarding or account setup.
FAQs about digital signature and encryption
These answers cover validation, compliance, and plan limits so teams can troubleshoot digital signature and encryption workflows with confidence.
If a signer sees a 21 CFR Part 11 workflow error, check whether the account has two-factor authentication, unique user IDs, and timestamped audit trails enabled. SignNow documents these controls in Enterprise and Site License setups for regulated workflows.
If a HIPAA review flags the workflow, confirm that a BAA is in place and the document is stored with encryption at rest. SignNow supports HIPAA compliance when the covered entity signs the required BAA.
If a document needs a qualified electronic signature for EU transactions, the standard Business plan is not enough. SignNow lists QES support on the Site License, while all plans support SES under eIDAS.
If a signer cannot complete an SMS OTP check, verify the phone number format and delivery network. SignNow supports stronger signer authentication workflows, including SMS OTP and ID verification, for higher-assurance transactions.
If a PDF audit trail looks incomplete, export the completed file and review the document history for timestamps, signer activity, and delivery records. SignNow preserves audit evidence for ESIGN and UETA disputes.
If role-based sending is not available, confirm the plan level and account permissions. SignNow’s Business Premium, Enterprise, and Site License plans add bulk send, advanced controls, and, on higher tiers, SSO and API access.
