> Ethereum address checksum with EIP-1191 support

## Usage

```js
var checksum = require('eth-checksum')

console.log(checksum.encode('0x27b1fdb04752bbc536007a920d24acb045561c26'))
console.log(checksum.verify('0x27b1fdb04752bbc536007a920d24acb045561c26'))

// With chain id
console.log(checksum.encode('0x27b1FdB04752BBc536007A920D24ACB045561c26', 30))
console.log(checksum.verify('0x27b1FdB04752BBc536007A920D24ACB045561c26', 30))
```

## API

### `const addrStr = checksum.encode(address, [chainId = null])`

Encode `address` with optional `chainId`. Can encode a `string` or a `Buffer`

### `const bool = checksum.verify(address, [chainId = null])`

Validate `address` with optional `chainId`. Can validate a `string` or a `Buffer`

## Install

```sh
npm install eth-checksum
```

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
