csr-gen

Generates an OpenSSL key and CSR

Install

  1. Make sure you have openSSL (try $ openssl if you aren't sure)
  2. npm package install
npm install csr-gen

OR download from github and place in ./node_modules

Usage

var csrgen = require('csr-gen');
var fs = require('fs');

var exportLocation = __dirname;
var domain = 'exampledomain.com';

csrgen(domain, exportLocation, {
    company: 'Example, Inc.',
    email: 'joe@foobar.com'
}, function(err){
    console.log('CSR created!')
    var csr = fs.readFileSync(__dirname + '/' + domain + '.csr');
    console.log('csr: '+csr);
});

CSR will perform the following shell command:

$ openssl req -nodes -newkey rsa:2048 -keyout ./exampledomain.com.key -out ./exampledomain.com.csr
