NodeJS: Validate certificate in DER format

Question

I'm using crypto module to validate a certificate, but both, my certificate and my public key are in DER format. It seems that crypto module does not accept this format.

Is there a way (or module) to convert DER to PEM format using NodeJS? I couldn't find any and cannot use command line to call openssl via shell.

UPDATE: It's not about HTTPS certificates. It's about general X.509 certificates. And if you mark the question as negative, please leave a comment to justify it. Don't be a stupid if you are not able to help.

Answer 1

Dominykas' answer was good, but in my case, I have a certificate that uses ECC and node-forge does not support it. So I've found a module called node-openssl-wrapper, which worked perfectly well because it encapsulates the openssl commands in a simple function call, like this:

co(function*() {
  var ossl = require('openssl-wrapper');
  var derCert = new Buffer('...'); // binary DER certificate
  var pemCert = yield ossl.qExec('x509', derCert, { inform: 'der', outform: 'pem' });
});
