PDF Cryptographic signature API

This is a simple docker project that will run a API that cryptograpically signs the PDF.

Assumptions

The project assumes JDK17 as the run time environment.

Installation

To pull the latest image use the following command:

docker pull anandsdocs/sdocs-pdfsignapi

To run once you have pulled the image:

docker run -e PORT=8080 -p 8080:8080 anandsdocs/sdocs-pdfsignapi:latest

Using the API

The API exposes two endpoints:

1. /sign/ping

This supports a HTTP GET and is there to make sure the API is up and working. It returns a simple Hello the time is 7/31/23, 2:47 PM

2. /ssign/

This is the API that signs the PDF and returns the signed PDF. This supports HTTP POST

Input

The API expects three parameters:

1. publicCert : This is the public certificate that is used to sign your PDF.
2. privateKey : This is the private key used to sign the PDF
3. pdfFileBase64: This is a base64 encoded string of your PDF file.

Sample request:

{
    "privateKey":"-----BEGIN PRIVATE KEY-----....",
    "publicCert":"-----BEGIN CERTIFICATE----- ...",
    "pdfFileBase64":"..."
}

Output

The output is a binary PDF file that can then be saved or rendered accordingly.
