JSON Web Tokens for Lua

**This plugin now lives here: ** https://github.com/jitsi/jitsi-meet/blob/master/resources/prosody-plugins/luajwtjitsi.lib.lua

## Usage

Basic usage:

```lua
local jwt = require "luajwtjitsi"

local key = "example_key"

local payload = {
	iss = "12345678",
	nbf = os.time(),
	exp = os.time() + 3600,
}

-- encode
local alg = "HS256" -- (default)
local token, err = jwt.encode(payload, key, alg)

-- token: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiIx(cutted)...

-- decode and validate
local decoded, err = jwt.verify(token, alg, key)

-- decoded: { ["iss"] = 12345678, ["nbf"] = 1405108000, ["exp"] = 1405181916 }
```

An openresty/nginx lua jwt auth example:

```
# nginx.conf
location /auth {
	content_by_lua '
		local jwt = require "luajwt"

		local args = ngx.req.get_uri_args(1)

		if not args.jwt then

			return ngx.say("Where is token?")
		end

		local key = "SECRET"

		local ok, err = jwt.decode(args.jwt, key)

		if not ok then

			return ngx.say("Error: ", err)
		end

		ngx.say("Welcome!")
	';
}
```

Generate token and try:

```bash
$ curl your.server/auth?jwt=TOKEN
```

## Algorithms

**HMAC**

* HS256	- HMAC using SHA-256 hash algorithm (default)
* HS384	- HMAC using SHA-384 hash algorithm
* HS512 - HMAC using SHA-512 hash algorithm

**RSA**

* RS256 - RSA using SHA-256 hash algorithm
* RS384 - RSA using SHA-384 hash algorithm
* RS512 - RSA using SHA-512 hash algorithm
