Digital Signature and Digital Certificate for signNow
Award-winning eSignature solution
What digital signature and digital certificate means
A digital signature and digital certificate is a secure way to sign electronic documents and prove who signed them. The certificate binds a signer’s identity to a public key, while the digital signature uses cryptography to lock the document to that identity. When a document is signed, the system creates a hash, signs it with a private key, and lets others verify it with the certificate’s public key. This helps confirm identity, detect changes, and preserve integrity for U.S. business records.
Why digital signatures and certificates matter
They reduce paper handling, speed approvals, and create evidence that supports enforceability under ESIGN and UETA when signer intent, consent, and attribution are documented.
Common digital signature pitfalls
Signer identity can be disputed when authentication is weak or audit records do not clearly tie the action to one person. Certificate revocation checks may fail if the workflow does not verify OCSP or CRL status before relying on the signature. Documents can become hard to defend in court when timestamps, IP data, and action history are incomplete. Teams may confuse a drawn electronic signature with a certificate-based digital signature, which creates inconsistent compliance expectations.
Who uses digital signatures and certificates
Documents and workflows
Lease agreements, patient forms, loan packets, and internal approvals move faster when identity and intent are captured electronically.
Industries and audiences
Real estate, healthcare, finance, legal services, education, and government teams use it for signed records and audit evidence.
Typical users of digital signatures
A NetSuite operations lead at Xerox uses signNow to route the right signatures to the right documents in the right format. The value is not just speed; it is control over approval paths, document versions, and system-connected records that support finance and operations teams across departments. A founder at Martin Properties uses signNow to execute lease and property documents online with mobile access and built-in security. The workflow fits real estate teams that need fast turnaround, clear signer attribution, and records that can be reviewed later without relying on paper files.

Core features and benefits
Digital signature and digital certificate workflows combine identity proof, document integrity, and recordkeeping in one controlled signing process.
Identity binding
The certificate links a signer to a public key, while the signature locks the document to that identity and reveals tampering.
Integrity check
Hash-based verification lets recipients confirm that the signed file has not changed after approval or transmission.
Audit trail
Audit records capture who signed, when they signed, and how the document moved through the workflow.
Signer verification
Authentication options can support stronger identity proofing for higher-risk transactions and regulated records.
Mobile access
Mobile signing keeps approvals moving on phones and tablets without changing the legal effect of the record.
Certificate status
Certificate validation can rely on revocation data, which helps confirm that the signing credential was still valid.
How the signing process works
The process follows a clear sequence from identity verification to cryptographic validation and record preservation.
Send request: The signer receives a document and a certificate-backed signing request. Verify signer: The system verifies identity and records the signing event. Create signature: A hash is created and signed with the private key. Verify record: Recipients validate the certificate and confirm document integrity.
Quick setup steps

FAQ and troubleshooting
These answers focus on signNow features, plan levels, and U.S. compliance standards that affect certificate-backed signing workflows.
signNow supports audit trails, signer authentication, and tamper-evident records on paid plans. For HIPAA workflows, use a plan that supports a BAA and keep retention aligned with 45 CFR §164.530(j)(2).
If a signer cannot complete the request, check the authentication method first. SMS OTP, ID verification, and other controls can be adjusted in the workflow, and stronger methods help when attribution matters more.
A missing audit trail usually means the workflow was not configured to capture the full event history. signNow records signing activity, timestamps, and document actions, which helps support ESIGN and UETA enforceability.
For regulated records under 21 CFR Part 11, use controls that support unique user identification, secure timestamps, and retained document history. signNow’s compliance features are designed to support those requirements in validated workflows.
If a document must be retained for healthcare use, keep it for 6 years from the later of creation or last effective date under HIPAA. signNow retention settings should match that policy.
If you need a lower-cost starting point, signNow Business begins at $8/user/month billed annually. More advanced needs, such as bulk send or advanced authentication, are available on higher plans.
