A Keepass KDBX v2/v3 parser for Crystal.

## Requirements

This library requires **libsodium**. On Ubuntu 17.04 you can install it via `sudo apt install libsodium-dev`. For other distros, please check [the libsodium docs](https://download.libsodium.org/doc/).

## Install

Add the following lines to your `shard.yml`:

```yaml
dependencies:
  keepass:
    github: lipanski/keepass
```

...and run `crystal deps` or `shards install`.

## Usage

When the file is encrypted with a password:

```crystal
require "keepass"

database = Keepass.parse!("/path/to/keepass.kdbx", "password")
```

When the file is encrypted with a password and a key file:

```crystal
require "keepass"

database = Keepass.parse!("/path/to/keepass.kdbx", "password", "/path/to/keyfile")
```
