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: '[email protected]'
}, 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
