Firma digital embebida

The iframe flow from the official Lakaut guide, end to end: a session token brokered server-side, a sample PDF handed over in lakaut.init, and the signed result verified against its published SHA-256 before it downloads.

Review the signer data below, then start a session.

Signer data

userData

Sent in lakaut.init. Prefilled for quick testing — edit anything before starting. * DNI or CUIL identifies the signer; everything else is optional, and the iframe asks for what it still needs.

Document

lakaut.load.file

A sample PDF rides along in the init. After the handshake you can swap in your own — 10 MB max, PDF only.

    The embed loads here once a session starts.

    Your backend brokers the token; the browser only ever sees a 30-minute session.
