Quickstart

Sign a PDF with a .pfx (or .p12 / .pem) and a visible green-tick appearance.

const atick = require("atick");
const fs = require("fs");

const pdf = fs.readFileSync("doc.pdf");
const pfx = fs.readFileSync("my.pfx");

const signed = atick.signPfx(pdf, pfx, JSON.stringify({
  password: "••••", cn: "Aniket Chaturvedi", reason: "Approved",
  green_tick: true, page: 1, rect: [300, 55, 575, 175],
  pades: true, timestamp: true, ltv: true,           // PAdES-B-LT
}));

fs.writeFileSync("signed.pdf", signed);

Open signed.pdf in Adobe Reader — for a trusted certificate it shows a valid green tick and “Signed and all signatures are valid.”

TypeScript

import * as atick from "atick";
import { readFileSync, writeFileSync } from "fs";

const signed = atick.signPfx(readFileSync("doc.pdf"), readFileSync("my.pfx"),
  JSON.stringify({ password: "••••", cn: "Aniket", pades: true, page: 1, rect: [300, 55, 575, 175] }));
writeFileSync("signed.pdf", signed);

A minimal, invisible signature

const signed = atick.signPfx(pdf, pfx, JSON.stringify({ password: "••••", placements: [], pades: true }));

Catching errors

try {
  atick.signPfx(pdf, pfx, JSON.stringify({ password: "wrong" }));
} catch (e) {
  console.error("signing failed:", e.message);
}

Next: see Signing for all the options, or the API reference.
