**Hetty** is an HTTP toolkit for security research. It aims to become an open
|
||
source alternative to commercial software like Burp Suite Pro, with powerful
|
||
features tailored to the needs of the infosec and bug bounty community.

|
||
## Documentation
|
||
|
||
📖 [Read the docs.](https://hetty.xyz/)
|
||
|
||
## Installation
|
||
|
||
Hetty compiles to a self-contained binary, with an embedded SQLite database
|
||
and web based admin interface.
|
||
|
||
### Install pre-built release (recommended)
|
||
|
||
👉 Downloads for Linux, macOS and Windows are available on the [releases page](https://github.com/dstotijn/hetty/releases).
|
||
|
||
### Build from source
|
||
|
||
#### Prerequisites
|
||
|
||
- [Go 1.16](https://golang.org/)
|
||
- [Yarn](https://yarnpkg.com/)
|
||
|
||
Hetty depends on SQLite (via [mattn/go-sqlite3](https://github.com/mattn/go-sqlite3))
|
||
and needs `cgo` to compile. Additionally, the static resources for the admin interface
|
||
(Next.js) need to be generated via [Yarn](https://yarnpkg.com/). The generated
|
||
files will be embedded (using the [embed](https://golang.org/pkg/embed/) package)
|
||
when you use the `build` Makefile target.
|
||
|
||
Clone the repository and use the `build` make target to create a binary:
|
||
|
||
```
|
||
$ git clone git@github.com:dstotijn/hetty.git
|
||
$ cd hetty
|
||
$ make build
|
||
```
|
||
|
||
### Docker
|
||
|
||
A Docker image is available on Docker Hub: [`dstotijn/hetty`](https://hub.docker.com/r/dstotijn/hetty).
|
||
For persistent storage of CA certificates and project databases, mount a volume:
|
||
|
||
```
|
||
$ mkdir -p $HOME/.hetty
|
||
$ docker run -v $HOME/.hetty:/root/.hetty -p 8080:8080 dstotijn/hetty
|
||
```
|
||
|
||
## Usage
|
||
|
||
When Hetty is run, by default it listens on `:8080` and is accessible via
|
||
http://localhost:8080. Depending on incoming HTTP requests, it either acts as a
|
||
MITM proxy, or it serves the API and web interface.
|
||
|
||
By default, project database files and CA certificates are stored in a `.hetty`
|
||
directory under the user's home directory (`$HOME` on Linux/macOS, `%USERPROFILE%`
|
||
on Windows).
|
||
|
||
To start, ensure `hetty` (downloaded from a release, or manually built) is in your
|
||
`$PATH` and run:
|
||
|
||
```
|
||
$ hetty
|
||
```
|
||
|
||
An overview of configuration flags:
|
||
|
||
```
|
||
$ hetty -h
|
||
Usage of ./hetty:
|
||
-addr string
|
||
TCP address to listen on, in the form "host:port" (default ":8080")
|
||
-adminPath string
|
||
File path to admin build
|
||
-cert string
|
||
CA certificate filepath. Creates a new CA certificate if file doesn't exist (default "~/.hetty/hetty_cert.pem")
|
||
-key string
|
||
CA private key filepath. Creates a new CA private key if file doesn't exist (default "~/.hetty/hetty_key.pem")
|
||
-projects string
|
||
Projects directory path (default "~/.hetty/projects")
|
||
```
|
||
|
||
You should see:
|
||
|
||
```
|
||
2020/11/01 14:47:10 [INFO] Running server on :8080 ...
|
||
```
|
||
|
||
Then, visit [http://localhost:8080](http://localhost:8080) to get started.
|
||
|
||
ℹ️ Detailed documentation is under development and will be available soon.
|
||
|
||
## Certificate Setup and Installation
|
||
|
||
In order for Hetty to proxy requests going to HTTPS endpoints, a root CA certificate for
|
||
Hetty will need to be set up. Furthermore, the CA certificate may need to be
|
||
installed to the host for them to be trusted by your browser. The following steps
|
||
will cover how you can generate your certificate, provide them to hetty, and how
|
||
you can install them in your local CA store.
|
||
|
||
⚠️ _This process was done on a Linux machine but should_
|
||
_provide guidance on Windows and macOS as well._
|
||
|
||
### Generating CA certificates
|
||
|
||
You can generate a CA keypair two different ways. The first is bundled directly
|
||
with Hetty, and simplifies the process immensely. The alternative is using OpenSSL
|
||
to generate them, which provides more control over expiration time and cryptography
|
||
used, but requires you install the OpenSSL tooling. The first is suggested for any
|
||
beginners trying to get started.
|
||
|
||
#### Generating CA certificates with hetty
|
||
|
||
Hetty will generate the default key and certificate on its own if none are supplied
|
||
or found in `~/.hetty/` when first running the CLI. To generate a default key and
|
||
certificate with hetty, simply run the command with no arguments
|
||
|
||
```sh
|
||
hetty
|
||
```
|
||
|
||
You should now have a key and certificate located at `~/.hetty/hetty_key.pem` and
|
||
`~/.hetty/hetty_cert.pem` respectively.
|
||
|
||
#### Generating CA certificates with OpenSSL
|
||
|
||
You can start off by generating a new key and CA certificate which will both expire
|
||
after a month.
|
||
|
||
```sh
|
||
mkdir ~/.hetty
|
||
openssl req -newkey rsa:2048 -new -nodes -x509 -days 31 -keyout ~/.hetty/hetty_key.pem -out ~/.hetty/hetty_cert.pem
|
||
```
|
||
|
||
The default location which `hetty` will check for the key and CA certificate is under
|
||
`~/.hetty/`, at `hetty_key.pem` and `hetty_cert.pem` respectively. You can move them
|
||
here and `hetty` will detect them automatically. Otherwise, you can specify the
|
||
location of these as arguments to `hetty`.
|
||
|
||
```
|
||
hetty -key key.pem -cert cert.pem
|
||
```
|
||
|
||
### Trusting the CA certificate
|
||
|
||
In order for your browser to allow traffic to the local Hetty proxy, you may need
|
||
to install these certificates to your local CA store.
|
||
|
||
On Ubuntu, you can update your local CA store with the certificate by running the
|
||
following commands:
|
||
|
||
```sh
|
||
sudo cp ~/.hetty/hetty_cert.pem /usr/local/share/ca-certificates/hetty.crt
|
||
sudo update-ca-certificates
|
||
```
|
||
|
||
On Windows, you would add your certificate by using the Certificate Manager. You
|
||
can launch that by running the command:
|
||
|
||
```batch
|
||
certmgr.msc
|
||
```
|
||
|
||
On macOS, you can add your certificate by using the Keychain Access program. This
|
||
can be found under `Application/Utilities/Keychain Access.app`. After opening this,
|
||
drag the certificate into the app. Next, open the certificate in the app, enter the
|
||
_Trust_ section, and under _When using this certificate_ select _Always Trust_.
|
||
|
||
_Note: Various Linux distributions may require other steps or commands for updating_
|
||
_their certificate authority. See the documentation relevant to your distribution for_
|
||
_more information on how to update the system to trust your self-signed certificate._
|
||
|
||
## Vision and roadmap
|
||
|
||
- Fast core/engine, built with Go, with a minimal memory footprint.
|
||
- Easy to use admin interface, built with Next.js and Material UI.
|
||
- Headless management, via GraphQL API.
|
||
- Extensibility is top of mind. All modules are written as Go packages, to
|
||
be used by Hetty, but also as libraries by other software.
|
||
- Pluggable architecture for MITM proxy, projects, scope. It should be possible.
|
||
to build a plugin system in the (near) future.
|
||
- Based on feedback and real-world usage of pentesters and bug bounty hunters.
|
||
- Aim for a relatively small core feature set that the majority of security researchers need.
