Digital Signature Certificates for signNow
Award-winning eSignature solution
What digital signature certificates do
A digital signature certificate (DSC) is a trusted digital ID that links a signer to a cryptographic key used to sign documents electronically. It helps verify identity, protect document integrity, and show whether a file changed after signing. In a U.S. workflow, the certificate supports attribution and evidence by pairing signer authentication, a hash of the document, and a tamper-evident signature record. signNow uses these controls to help organizations manage signed records with clear audit evidence.
Why digital signature certificates matter
Digital signature certificates help organizations prove who signed, preserve document integrity, and reduce disputes over authenticity. Under ESIGN and UETA, electronic signatures can be enforceable when intent, consent, and attribution are documented.
Common DSC implementation issues
Signer identity can be hard to prove when authentication is weak or inconsistent across documents. Expired or revoked certificates can break trust during later verification or legal review. Poor retention practices can leave signed records without enough evidence for audits or disputes. Mismatched workflows across teams can create gaps in audit trails, approvals, and signer intent.
Who uses digital signature certificates
Regulated teams
Healthcare, finance, real estate, and legal teams use DSCs for regulated signatures and records.

Core features and benefits
Digital signature certificates add identity assurance, document integrity, and verifiable signing records to electronic workflows without adding unnecessary process complexity.
Identity link
Links each signature to a verifiable identity record, helping teams support attribution and reduce disputes about who signed.
Tamper evidence
Creates a tamper-evident record so later changes are easier to detect during review, audit, or litigation.
Audit history
Captures signer activity in a structured history that supports internal controls and external compliance checks.
Authentication controls
Supports stronger authentication methods, including multi-factor verification, for higher-assurance signing workflows.
Document integrity
Works with signed PDFs and related records so teams can store, retrieve, and verify completed documents more easily.
Workflow consistency
Helps standardize signing across departments, which reduces manual handling and improves process consistency.
How DSC signing works
The signing flow follows a clear sequence, from identity verification to a verifiable record that can be reviewed later.
Authenticate: The signer receives a document and completes authentication. Capture: signNow records the signing event and document hash. Bind: The certificate binds the signer to the signed file. Verify: The completed record stays verifiable through audit evidence.
Quick setup steps
Use a short setup flow to prepare, send, and retain certificate-backed signing records in a controlled process.

Recommended workflow setup
A certificate-backed workflow works best when identity checks, retention rules, and encryption are defined before the first document is sent.
| Setting | Recommendation |
|---|---|
| Authentication method | SMS OTP with ID review |
| Signature type | Cryptographic digital signature |
| Audit trail | Full timestamped event log |
| Document retention | 6 years for HIPAA records |
| Encryption | TLS 1.2/1.3 and AES-256 |
Platform and device requirements
Digital signature certificate workflows run in modern browsers and mobile apps, with secure connections over TLS for document access and signing.
Desktop browsers Chrome, Firefox, Safari, and Edge support web signing. Operating systems Windows, macOS, iOS, and Android are supported. Mobile devices signNow mobile apps support signing on phones and tablets.
For regulated deployments, managed devices, access controls, and retention policies matter as much as browser support. signNow works across desktop and mobile environments, while enterprise teams can pair it with SSO, API access, and document controls to fit internal policy and compliance needs.

Real-world examples
Customer stories show how certificate-backed signing fits real operational work, especially where identity, speed, and record quality matter.
NetSuite operations
A NetSuite operations leader needed flexible signing across document formats and approval paths.
- Kodi-Marie Evans, Director of NetSuite Operations at Xerox, described the need for the right signatures on the right documents.
signNow helped Xerox align signing with NetSuite-based workflows, improving format control and document routing while keeping the process easier to manage across teams.
Real estate
A real estate founder needed online execution for property documents with clear compliance and mobile access.
- Tim Martin, Founder at Martin Properties, highlighted 100% compliance and built-in security.
signNow supported online execution for property paperwork, including mobile and offline use, while preserving the compliance and security controls needed for real estate transactions.

FAQ and troubleshooting
These answers focus on plan limits, compliance needs, and evidence handling for certificate-backed signing in signNow.
signNow Business includes legally binding eSignatures, audit trails, templates, and mobile apps. If a document needs HIPAA support, a BAA is required, and the workflow should keep audit evidence and retention controls intact.
signNow supports ESIGN and UETA enforceability when intent, consent, and attribution are documented. For higher-assurance workflows, use stronger authentication and keep the completed record with its audit trail.
HIPAA use requires a signed BAA and controls for access, integrity, and audit logging. signNow’s compliance posture supports those needs, but the covered entity must configure retention and access policies correctly.
The Business Premium plan adds bulk send, while Enterprise adds advanced signer authentication and integrations. If you need higher-volume routing, choose the plan that matches your document volume and approval structure.
For regulated records, keep the signed file, audit trail, and related consent evidence together. That helps support admissibility under ESIGN, UETA, and, where relevant, HIPAA or 21 CFR Part 11 workflows.
signNow’s paid plans include unlimited users, but some advanced controls are tied to higher tiers or the Site License. If your team needs SSO or full API access, review the plan details first.
