Generates SSH key-pairs
npm install ssh-keygen-lite


Generates a SSH key-pair using.
1. Make sure you have ssh-keygen installed in your machine. Try $ ssh-keygen if you aren't sure
2. Run npm install ssh-keygen-lite if you're using NPM
> TIP: If you set a non-empty string to the environment variable VERBOSE, you'll enable the verbose mode.
> Logs from the lib are prefixed by ssh-keygen-lie: while logs from the binary ssh-keygen are emitted with the prefix ssh-keygen:
``js
// With CommonJS
const path = require('path');
const keygen = require('ssh-keygen-lite');
keygen(
{
// sshKeygenPath: 'ssh-keygen',
location: path.join(__dirname, 'foo_rsa'),
type: 'rsa',
read: true,
force: true,
destroy: false,
comment: 'joe@foobar.com',
password: 'keypassword',
size: '2048',
format: 'PEM',
},
// If you omit this callback function, a Promise will be returned instead!
function onDoneCallback(err, out) {
// The error could be related to ssh-keygen binary or file system errors.
if (err) return console.error('Something went wrong:', err);
console.log('Keys created!');
console.log('private key:', out.key);
console.log('public key:', out.pubKey);
},
);

#### Parameters
- location: desired location for the key. The public key will be at the location + .pub. Defaults to a file called id_rsa inside a temporary directorytype
- : type of the SSH key that is generated. Defaults to rsa.read
- : should the callback have the key files read into it. Defaults to trueforce
- : destroy pre-existing files with the location name and the public key name. Defaults to truedestroy
- : destroy the key files once they have been read. Defaults to falsecomment
- : the comment that should be embedded into the key. Defaults to an empty stringpassword
- : the password for the key. Falsy values will turn this into an empty string. Defaults to an empty stringsize
- : Specifies the number of bits (as string) in the key to create. Defaults to '2048'format
- : Specify a key format for key generation. Defaults to 'RFC4716'
#### Promise-based API
> NOTE: You'll need NodeJS version 8 or later because it's rely on util.promisify utility.
If you don't supply the second parameter to keygen (ie., the callback), then it will return a Promise that resolves to an plain object with key and pubkey properties.
The following shell command will get executed:
`bash`
$ ssh-keygen -t rsa -b 2048 -C "joe@foobar.com" -N "keypassword" -m PEM -f ./foo_rsa
Generating public/private rsa key pair.
Your identification has been saved in ./foo_rsa.
Your public key has been saved in ./foo_rsa.pub.
The key fingerprint is:
02:f7:40:b6:c7:b3:a3:68:16:53:dd:86:63:df:b5:33 joe@foobar.com
The key's randomart image is:
+--[ RSA 2048]----+
| o |
| o + o |
| . = O o . |
| + = * . . . |
| o . S . . E |
| + o . o |
| + . |

+-----------------+
It is advisable to generate your keys on a machine with a significant random source like one with a mouse/trackpad.
