## Getting started

In order to access the provided cryptographic functions, an instance of ElGamal

should be generated or initialized with custom parameters.

``` js

import ElGamal from 'elgamal';

const eg = await ElGamal.generateAsync(); // Recommended way of initialization

const egCustom = new ElGamal(prime, generator, publicKey, privateKey);

```

### Encryption and decryption

```js

const secret = 'The quick brown fox jumps over the lazy dog';

const encrypted = await eg.encryptAsync(secret);

const decrypted = await eg.decryptAsync(encrypted);

console.log(decrypted.toString() === secret); // true

```
