Node.js https pem error: routines:PEM_read_bio:no start line

Question

I am messing with login form right now with node.js, I tried creating a pem key and csr using

openssl req -newkey rsa:2048 -new -nodes -keyout key.pem -out csr.pem

However I been getting errors for running node server.js

Here is my server.js

var http = require('http'),
    express = require('express'),
UserServer = require('./lib/user-server');

var https = require('https');
var fs = require('fs');

var options = {
  key: fs.readFileSync('./key.pem', 'utf8'),
  cert: fs.readFileSync('./csr.pem', 'utf8')
};

var app = express();

app.configure(function(){
  app.use(express.bodyParser());
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));
});

var httpserver = http.createServer(app).listen('3004', '127.0.0.1');
var https_server = https.createServer(options, app).listen('3005', '127.0.0.1');
UserServer.listen(https_server);

Here is the error

crypto.js:104
  if (options.cert) c.context.setCert(options.cert);
                          ^
Error: error:0906D06C:PEM routines:PEM_read_bio:no start line

    at Server (tls.js:1107:28)
    at new Server (https.js:35:14)
    at Object.exports.createServer (https.js:54:10)

I tried running

openssl x509 -text -inform DER -in key.pem

It gives

unable to load certificate
140735208206812:error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag:tasn_dec.c:1319:

I am not exactly sure what does the error mean as my encryption file is .pem file already, so any help would be much appreciated.

Thanks

Answer 1

You are probably using the wrong certificate file, what you need to do is generate a self signed certificate which can be done as follows

openssl req -newkey rsa:2048 -new -nodes -keyout key.pem -out csr.pem
openssl x509 -req -days 365 -in csr.pem -signkey key.pem -out server.crt

then use the server.crt

   var options = {
      key: fs.readFileSync('./key.pem', 'utf8'),
      cert: fs.readFileSync('./server.crt', 'utf8')
   };
