Create digitally signed pdf nodejs

Question

I recently tried to create pdf by nodejs.

And I finally found PDFKit .

This library works well, but I need to implement part of the digital signature.

But most of the implementation is for JAVA or C #, such as iText or VersyPDF.

Plz give me some suggestion ... thanks

Answer 1

I am currently working on the npm node-signpdf package (at the time of this writing, version 0.0.3). In the test code, you can see the readable fragment of the PDF-generation and signature .

I know that this answer comes years after the initial question, but it’s very difficult for me to understand all this, so I hope this answer helps someone.

Answer 2

[disclosure: I work for CoSign]

You can use the low or high level APIs to add digital signatures to PDF documents.

For quick and complete integration, check out CoSign's Signature Web Agent .

Update

If you want to control the user interface of the signing process, you can use the CoSign SAPI WebServices API.

Signing using a device against a local certificate: the problem is that storing a digital signature certificate on a PC or server is not recommended because such machines are not Signature Protection Devices (SSCD). Instead, either a centralized, hardened server (such as CoSign), smart cards, or a SAAS solution is considered preferred. And for regulated industries, SSCD is often required.

In addition to security issues, working with local certificates or smart cards / readers / drivers is an expensive administrative burden. A centralized signature server lowers TCO .
