* Encryption example using Cipher

```js
const crypto = require('crypto');  
const cipher = crypto.createCipher('aes192', 'a password');  

const encrypted = cipher.update('Hello Node.js', 'utf8', 'hex');  
encrypted += cipher.final('hex');

with legacy programs that expect `'binary'` to be the default encoding.

New applications should expect the default to be `'buffer'`. This property may
become deprecated in a future Node.js release.

### crypto.createCipher(algorithm, password)

Creates and returns a `Cipher` object that uses the given `algorithm` and
`password`.
