Compliance with business vision and solid technical foundation

An institutional layer to build management confidence and a technical layer to run in production.

Institutional

For decision-makers accountable for operations

  • Standardizes diploma signing across departments and campuses.
  • Strengthens controls for audits and regulatory requirements.
  • Reduces dependence on manual and improvised flows.
  • Enables scale planning for peak-volume periods.

Technical

For those who integrate, monitor and maintain

  • Dedicated diploma endpoint: `POST /api/v1/signatures/xml/diploma`.
  • Control parameters by step: `target_tag`, `signature_policy`, `signature_method`.
  • RFC3161 timestamp support via `request_options[timestamp]`.
  • Asynchronous flow with webhooks for operational monitoring.
  • Integration with Connector JS + Agent for local A3 certificate signing.

Digital diploma signing architecture

A single workflow with Connector JS, unifying operational vision and technical implementation.

1. Secretaria / ERP

Starts session in Connector

Sends XML and sets profile `xml-xades-diploma`.

2. IE (e-CNPJ)

Signs `DadosDiploma`

`agent_local` with A3 token/card via Agent Desktop.

3. Resp. legal (e-CPF)

Signs `Diploma` (RA)

`remote_provider` in the cloud with RA policy.

4. Result for HEI

Signed and auditable XML

Returns metadata, status and traceability for governance.
