Web content sanitizer proxy as a service

Morty rewrites web pages to exclude malicious HTML tags and attributes. It also replaces external resource references to prevent third party information leaks.

The main goal of morty is to provide a result proxy for [searx](https://asciimoo.github.com/searx/), but it can be used as a standalone sanitizer service too.

Features:

 - HTML sanitization
 - Rewrites HTML/CSS external references to locals
 - JavaScript blocking
 - No Cookies forwarded
 - No Referrers
 - No Caching/Etag
 - Supports GET/POST forms and IFrames
 - Optional HMAC URL verifier key to prevent service abuse


## Installation and setup
Requirement: Go version 1.10 or higher.

```
$ go get github.com/asciimoo/morty
$ "$GOPATH/bin/morty" --help
```

### Environment variables

Morty can be configured using the following environment variables:
- `MORTY_ADDRESS`: Listen address (default to `127.0.0.1:3000`)
- `MORTY_KEY`: HMAC url validation key (base64 encoded) to prevent direct URL opening. Leave blank to disable validation. Use `openssl rand -base64 33` to generate.
- `DEBUG`: Enable/disable proxy and redirection logs (default to `true`). Set to `false` to disable.
