jsignpdf v1.1.1

Node Wrapper for JSignPdf

Programatically add Digital Signatures (PKCS #12 certificates, .p12 or .pdfx) to PDFs.

Based on JSignPDF by @kwart

JSignPdf is a Java application which adds digital signatures to PDF documents. The application uses the OpenPDF library for PDF manipulations.

Project home-page: jsignpdf.sourceforge.net

This node wrapper uses child_process.exec and temp files to asynchronously run java app JSignPDF in non-interactive mode.

Requires Java.

Quick Usage

import signPDF from 'jsignpdf'

const signed : Buffer = await signPDF(
  pdf : Buffer,         // your existing PDF
  p12 : Buffer,         // your signing p12 certificate 
  pass ?: string,       // passhrase to your certificate (optional)
  options ?: { ... }    // see options
)
// => Signed PDF as a Buffer
