#### Encrypt and decrypt *String* data with PGP keys
```js
var options, encrypted;
const openpgp = require('openpgp') // use as CommonJS, AMD, ES6 module or via window.openpgp
openpgp.initWorker({ path:'openpgp.worker.js' }) // set the relative web worker path
var pubkey = '-----BEGIN PGP PUBLIC KEY BLOCK ... END PGP PUBLIC KEY BLOCK-----';
var privkey = '-----BEGIN PGP PRIVATE KEY BLOCK ... END PGP PRIVATE KEY BLOCK-----'; //encrypted private key
var passphrase = 'secret passphrase'; //what the privKey is encrypted with
// put keys in backtick (``) to avoid errors caused by spaces or tabs
const pubkey = `-----BEGIN PGP PUBLIC KEY BLOCK-----
...
-----END PGP PUBLIC KEY BLOCK-----`
const privkey = `-----BEGIN PGP PRIVATE KEY BLOCK-----
...
-----END PGP PRIVATE KEY BLOCK-----` //encrypted private key

data: 'Hello, World!', // input as String (or Uint8Array)
