For enterprises that need signed data to stay inside their own environment

E-Sign+: Cryptographic E-Signatures For Form Data You Control

Form.io E-Sign+ lets teams capture and verify digital signatures directly against submission data, inside their own self-hosted environment, without handing sensitive workflows to a third-party e-signature platform or forcing every signature into a PDF process.

Most E-Signature Workflows Still Treat Digital Work Like Paper

When the signature depends on a document export, a vendor account, or a separate PDF workflow, your proof of agreement starts drifting away from the system where the real data lives.

Without E-Sign+

  • Sensitive form data may leave your security boundary just to complete a signature step.
  • The signed proof is tied to a document artifact instead of the live submission record your application already uses.
  • You have to trust a third-party system with the signature evidence, audit trail, and cryptographic proof.

With Form.io E-Sign+

  • The signature happens inside your own Form.io environment, against the submission data itself.
  • Signed values are cryptographically verified, and changes invalidate the signature automatically.
  • You keep control of the data, the signature record, the APIs, and the cryptographic key strategy.

What E-Sign+ Actually Proves

Not merely that someone drew or typed a signature. It proves that the signed data and its context have not changed since the moment of signing.

E-Sign+ creates a cryptographic signature for the selected submission data, form context, and configured submission properties. If the protected values change later, the signature no longer validates.

That distinction matters. In regulated workflows, the question is not only, “Was there a signature?” The harder question is, “Can we prove this is still the same data that was signed?”

Form.io answers that question at the data layer, where the submission already lives.

Why Enterprises Use E-Sign+

Because high-stakes signatures need more than a visual mark on a PDF. They need data integrity, ownership, auditability, and deployment control.

Zero-trust digital signature deployment

Zero-Trust By Design

The signature process runs inside your application environment, so sensitive submission data and signature evidence do not need to move to an external provider.

API-driven digital signatures

API-Driven Access

Signed data remains accessible through the native Form.io submission ID and APIs, keeping signatures connected to the application workflow.

Digital signatures decoupled from PDFs

Decoupled From PDFs

Create immutable data snapshots inside your application without requiring a PDF-first process, while still exporting to PDF when the workflow requires it.

Private key control for e-signatures

Bring Your Own Keys

Use your own private keys, store them outside the deployment when needed, or integrate cryptographic operations through AWS KMS.

Built For Signed Workflows Where Data Cannot Be In Question

Especially when the signature is part of a larger form-driven process, not a standalone document transaction.

Heaelthcare Industry

Healthcare Consent And Intake

Capture consent against the exact patient data, disclosures, and form context inside the healthcare workflow your application already manages.

Finance & Banking Industry

Financial Approvals And Disclosures

Protect approvals, loan terms, underwriting decisions, disclosures, and internal sign-offs with tamper-evident validation.

Government

Government And Insurance Workflows

Keep applications, attestations, approvals, and regulated submissions inside the environment where governance and auditability are already enforced.

Are You Going To Build Signature Infrastructure Yourself?

The hard part is not putting a signature field on a form. It is proving, later, that the signed data, form definition, and relevant submission context are still intact.

That requires cryptographic signing, revision-aware submission handling, invalidation behavior, API access, key management, signature metadata, and a user-facing stamp that makes validity understandable.

E-Sign+ gives self-hosted Form.io customers a governed digital signature module without forcing the organization into disconnected document infrastructure.

What E-Sign+ Helps You Avoid

  • Exporting sensitive workflows into third-party e-signature platforms.
  • Building and maintaining a custom cryptographic signature layer around your form workflows.
  • Relying on signatures that look complete visually but do not prove the underlying submission data is unchanged.

How E-Sign+ Works

Configure what a signature protects, capture the signature inside the form, then let Form.io validate whether the protected data still matches.

1

Define

Select the component that acts as the signature and choose whether it protects specific fields, all form data, or selected submission properties.

2

Sign

Use a compatible field type, including text fields, checkboxes, dates, email fields, or a traditional signature component, to capture the signing action.

3

Verify

Display a configurable signature stamp and validate whether the signed values, form revision, and selected context remain unchanged.

Keep Digital Signature Trust Inside Your Own Environment

Use E-Sign+ when signed data, cryptographic proof, and auditability need to stay connected to the Form.io submissions, APIs, and deployment controls your organization already depends on.
