# @polkadot/util-rlp
Encoding and decoding for [Ethereum RLP structures](https://github.com/ethereum/wiki/wiki/%5BEnglish%5D-RLP). This is port of the original [EthereumJS RLP](https://github.com/ethereumjs/rlp) to cater for `Uint8Array` outputs (instead of `Buffer`) in addition to typings.
## Available Utilities
For a list of currently exposed methods, see the [library documentation](docs/README.md).

# Available interfaces
Utility methods to encode and decode [Ethereum RLP](https://github.com/ethereum/wiki/wiki/RLP). Adapted from the [EthereumJS implementation](https://github.com/ethereumjs/rlp/blob/0ce09db81fc303fcee593f7cc094ba44015f9b92/index.js)
# Available methods
## decode
Decodes the input RLP.
```js
decoder (input?: Uint8Array): Uint8Array | Array<*>
```
From an input, decod the RLP and return the result as a `Uint8Array` or `Array`.
```js
import { decode } from '@polkadot/util-rlp';
encode(new Uint8Array([0x83, 0x64, 0x6f, 0x67])) // => 'dog' as Uint8Array
```
## encode
Encodes the input value into RLP.
```js
encode (input: any): Uint8Array
```
From an input, calculate the RLP and return the result as a `Uint8Array`.
```js
import { encode } from '@polkadot/util-rlp';
encode('dog') // => [0x83, 0x64, 0x6f, 0x67]
