console.log(base32Encode(buffer, 'Crockford'))
//=> EHJQ6X0

console.log(base32Encode(buffer, 'RFC4648'))
//=> ORSXG5A=

console.log(base32Encode(buffer, 'RFC4648', { padding: false }))
//=> ORSXG5A

console.log(base32Encode(buffer, 'RFC4648-HEX'))
//=> EHIN6T0=
```

## API

### base32Encode(buffer, variant, options)

- `buffer` <ArrayBuffer>
- `variant` <String>
- `options` <Object>
  - `padding` <Boolean>

Encode the data in `buffer`. `variant` should be one of the supported variants
listed below.

- `'RFC3548'` - Alias for `'RFC4648'`
- `'RFC4648'` - [Base32 from RFC4648](https://tools.ietf.org/html/rfc4648)
- `'RFC4648-HEX'` - [base32hex from RFC4648](https://tools.ietf.org/html/rfc4648)
- `'Crockford'` - [Crockford's Base32](http://www.crockford.com/wrmg/base32.html)

Options may have a `padding` property which provides a way to forcefully enable or disable padding. The default behavior is to follow the default of the selected variant.
