Sep 12, 2015 node-rsa-keygen. Generates a RSA keypair using native OpenSSL library. This code is loosely based on ursa RSA generation code. As from node 0.11 the crypto library has publicEncrypt and privateDecrypt functions, we don't need to rely on any external libraries for public-key cryptography. Install the library.

As from node 0.11 the crypto library has publicEncrypt and privateDecrypt functions, we don't need to rely on any external libraries for public-key cryptography. Very straight forward process. Not complicated at all, I would say that the most difficult part would be to actually tweak the options, however the code below actually works and provides you the time it took to generate the key pair as well, just for informational purposes.

Performance

Performance greatly depends on the bit size of the generated private key. With 1024 bits you get a key in 0.5s-2s, with 2048 bits it takes 8s-20s, on the same machine. As this will block the event loop while generating the key,make sure that's ok or to spawn a child process or run it inside a webworker.

Pro Tip: authorized_keys

@maxogden found out how to use this module to create entries for the authorized_keys file:

API

Nodejs Generate Rsa Key Pair

keypair([opts])

Get an RSA PEM key pair.

opts can be

bits: the size for the private key in bits. Default: 2048.
e: the public exponent to use. Default: 65537.

Installation
