certpem.js

Read basic info from a cert.pem / x509 certificate.

Used for Greenlock.js

Install

# bin 
npm install --global certpem
 
# node.js library 
npm install --save certpem

Usage

CLI

For basic info (subject, altnames, issuedAt, expiresAt):

certpem /path/to/cert.pem

Output all info by passing --debug or use --json to see the basic info pretty-printed.

node.js

'use strict';
 
var certpem = require('certpem').certpem
var cert = fs.readFile('cert.pem', 'ascii', function (err, certstr) {
 
  // basic info
  console.info(certpem.info(certstr));
 
  // way too much info
  // (requires npm install --save node.extend@1)
  console.info(certpem.debug(certstr));
 
});

Example output:

{
  "subject": "localhost.example.com",
  "altnames": [
    "localhost.example.com"
  ],
  "issuedAt": 1465516800000,
  "expiresAt": 1499731199000
}

With a few small changes this could also work in the browser (that's how its dependencies are designed).
