# CCryptoLib

An integrated collection of cryptographic primitives written in Lua using the ComputerCraft system API.

## Initializing the Random Number Generator

All functions that take secret input may query the library's random generator,

`ccryptolib.random`. CC doesn't have high-quality entropy sources, so instead of

hoping for the best like other libraries do, CCryptoLib shifts that burden into

*you!*

If you trust the tmpim Krist node, you can fetch a socket token and use it for

initialization:

```lua

local random = require "ccryptolib.random"

-- Fetch a WebSocket token.

local postHandle = assert(http.post("https://krist.dev/ws/start", ""))

local data = textutils.unserializeJSON(postHandle.readAll())

postHandle.close()

-- Initialize the generator using the given URL.

random.init(data.url)

-- Be polite and actually open the socket too.

http.websocket(data.url).close()

```

Otherwise, you will need to find another high-quality random entropy source to

initialize the generator. **DO NOT INITIALIZE USING MATH.RANDOM.**
