Encrypted Digital Signature for signNow Compliance Guide

Award-winning eSignature solution

What a digital signature is

A digital signature is encrypted information that proves who signed a document and whether it changed after signing. It uses cryptography to bind the signer’s identity to the file, often through a public and private key pair. When the signer applies the signature, the system creates a hash of the document, encrypts that hash, and records the result. Anyone with the public key can verify the signature and detect tampering, which supports secure, traceable electronic transactions in the U.S.

Why encrypted signatures matter

A digital signature is encrypted information helps reduce paper handling, speed approvals, and preserve evidence of intent. Under ESIGN and UETA, it can be legally effective when attribution, consent, and record integrity are established, which makes it useful for routine and regulated U.S. workflows.

Why teams look for DocuSign alternatives

Common implementation issues

Signer identity can be hard to prove when authentication is weak or shared inboxes are used.
Documents may lose evidentiary value if timestamps, hashes, or audit logs are incomplete.
Teams can confuse a drawn e-signature with a cryptographic digital signature.
Regulated records may fail review if retention, access control, or BAA requirements are missed.

Business use cases

Legal teams, lenders, and operations groups use it for contracts, approvals, and records that need traceable consent.

Regulated documents

Healthcare, real estate, finance, and education use it for forms, disclosures, and permissions with compliance needs.

Real-world users and roles

Manages lease packets, renewals, and tenant approvals in high-volume property workflows. signNow customer stories from real estate teams show faster turnaround when documents move from office desks to mobile signing without losing auditability or consent records.
Coordinates patient forms, intake packets, and internal approvals while keeping HIPAA requirements in view. Healthcare teams benefit when signatures, access controls, and retention rules stay tied to the same electronic record, especially in mobile and remote workflows.

Document integrity

Creates a tamper-evident record that links the signer to the exact document version, helping preserve integrity after approval.

Cryptographic proof

Uses cryptographic verification so recipients can confirm the signature and detect changes without relying on paper copies.

Audit evidence

Supports traceable approvals with timestamps, signer details, and event history that help explain who acted and when.

Legal support

Fits U.S. electronic transaction rules when consent, attribution, and record retention are handled correctly.

Workflow speed

Reduces manual routing by moving signatures into a repeatable digital workflow across teams and locations.

Mobile access

Works across desktop and mobile signing flows, which helps people sign where they already work.

Connected workflows and systems

Connected systems move signed documents into the tools teams already use, reducing duplicate entry and keeping records aligned.

How encrypted signatures work

The signing flow follows a simple cryptographic sequence that ties identity, document integrity, and verification together.

Open document: The signer opens the document and reviews the content.
Verify identity: The system verifies identity with the chosen authentication method.
Create signature: A cryptographic hash is created and signed.
Confirm integrity: Recipients verify the signature and detect later changes.

Setting	Recommendation
Authentication method	SMS OTP
Signature type	Advanced electronic signature
Audit trail	Timestamped event log
Document retention	6 years for HIPAA records
Encryption	TLS 1.2/1.3 and AES-256

Platform and device requirements

Use a modern browser or mobile device with a secure connection to review, sign, and store documents.

Desktop browsers Chrome, Firefox, Safari, and Edge support web signing.
Operating systems Windows, macOS, iOS, and Android are supported.
Security connection TLS 1.2 or later is required.

For enterprise deployments, managed devices, SSO, and API-based provisioning help keep access controlled across teams. Regulated workflows may also require retention controls, certificate validation, and exportable records for review.

Real estate workflow

A real estate team needs faster lease execution without losing document control.

Tim Martin at Martin Properties used online execution for mobile and offline signing.

The result was 100% compliance, built-in security, and faster return of signed forms to the right parties.

Operations integration

A technology operations team needs better routing across systems and document formats.

Kodi-Marie Evans at Xerox relied on NetSuite integration for the right signatures in the right formats.

The workflow stayed aligned with internal systems, which improved document handling and reduced manual coordination across teams.

Best practices for secure signing

Good signing practices keep records easier to verify, store, and defend if a transaction is reviewed later.

Match authentication to risk

Use stronger authentication for higher-risk documents, and reserve simple email links for low-risk approvals where attribution is still clear.

Preserve the full record

Keep the signed PDF, audit trail, and related emails together so the record stays complete during review or dispute.

Align retention with law

Set retention rules to match the governing law, such as HIPAA’s 6-year retention period for covered records.

Control user access

Limit signer access to the minimum needed, and review provisioning when staff change roles or leave the organization.

FAQ and troubleshooting

These answers focus on plan limits, compliance needs, and recordkeeping details that affect signing in U.S. workflows.

signNow Business includes legally binding eSignatures, audit trails, templates, mobile apps, and unlimited users. For HIPAA workflows, use a BAA and keep retention controls in place.

signNow supports HIPAA when a BAA is in place. The platform also lists SOC 2 Type II, ISO 27001, GDPR, and ESIGN/UETA support for regulated U.S. workflows.

The 7-day free trial is available without a credit card. Paid plans start with Business at $8/user/month billed annually, and all paid plans include unlimited users.

For higher-assurance signing, use stronger authentication such as SMS OTP or ID verification. Weak methods like KBA are less suitable for sensitive transactions.

DocuSign has a 100 envelopes per user per year cap on some tiers. signNow Business has no such cap, which matters for high-volume teams.

For FDA-regulated records, use controls that support 21 CFR Part 11, including secure audit trails, unique user IDs, and time-stamped records.
