Automate ssh-keygen command for generating RSA keypairs
npm install ssh-keygen2ssh-keygen2
===========
Automate ssh-keygen command for generating RSA keypairs
This module is useful if you want:
- encrypted PEM format (keypair
and rsa-json do not support this)
- ssh-format, single-line pubkey (again not supported by the above modules)
- fingerprint (supported by ssh-keygen
but requires a second function call)
- error handling (errors are not handled by ssh-keygen)
- option to keep the resulting key files, or clean them up
(ssh-keygen's destroy option does nothing)
- randomart.
This is just a wrapper around ssh-keygen, so it requires that
command to be installed and in the path.
``js
var keygen = require('ssh-keygen2')
, assert = require('assert')
// generate a temporary keypair and return details
keygen(function (err, keypair) {
assert.ifError(err);
console.log(keypair.private);
console.log(keypair.public);
console.log(keypair.fingerprint + '\n');
console.log(keypair.randomart + '\n');
});
`
This outputs:
