Lacuna Demo Site

Sign a batch

Sign several PDFs with one authorization at your PSC: CloudHub, on the server, reaches your PSC, which signs each PDF's hash in one signature session, and PKI SDK, on the server, builds each signature.

Copies a prompt for your AI coding agent: “Sign a batch (Cloud certificate, with CloudHub)”, with its docs, samples in every language, call sequence and patterns to copy.

Files to sign

The five sample invoices are fictitious Brazilian invoices, so they are in Portuguese, and each is marked AMOSTRA (sample).

Find your PSC

Your private key stays at your PSC: only each PDF's hash goes there, through CloudHub. The PDFs, the signed PDFs and your public certificate stay in the Demo Site's server memory for this demo session only. The Demo Site stores nothing.
