cert-downloader

(Apple) SSL Certificate downloader. Downloads and optionally converts an SSL certificate.

This is a helper module that allows you to dowload an SSL certificate, by default that of Apple Inc..

Offered functionality:

• Download certificate and store locally.
• Convert certificate to PEM format.
• Validate a file against the certificate.

NOTE OpenSSL or compatible must be installed on your system if you wish to use certificates in the PEM format. Without this tool, only the download function will work.

Install

$ npm install cert-downloader

Usage

var CertDownloader = require('cert-downloader');
var certDl = new CertDownloader();

// download and save in default (cache) location
certDl.cert(function (error, certificatePath) {
    if(error) {
        console.error('Error ' + error);
    } else {
        console.log('Certificate downloaded to ' + certificatePath);
        // /nodeproject/certificate/AppleIncRootCertificate.cer
    }
});

// download and convert to PEM (will use cached cer file and convert that to pem)
certDl.pem(function (error, certificatePath) {
    if(error) {
        console.error('Error ' + error);
    } else {
        console.log('Certificate downloaded to ' + certificatePath);
        // /nodeproject/certificate/AppleIncRootCertificate.pem
    }
});

// verifiy an existing file against the certificate
// (will download and convert if required)
var file = '/nodeproject/certicate/file-to-verify';
certDl.verify(file, function(error, output) {
    if(error){
      return callback('File verification failed: ' + error);
    }
    console.log('Verified output: ' + output);
  });
