# Alaska - Go client for Certstream

Alaska is a small wrapper around the Go client for Certstream. It allows you to
get the certificates in real time and save them in a SQLite database. There is
an small front end in React (imported remotely) and an API with Gin Gonic.

## Install

```
git clone github.com/christalib/alaska
go build cmd/alaskad.go
go build server.go
```

You need a version of Go that has go modules.

## Run

You can run only the server as:

```
./server
```

If you don't have already a database, it will create a `certs.db` database for
you and run the appropriate migrations.

And there is a command line tool to allow you to get the certstream stream:

```
./alaskad
```

After, visit [http://localhost:3000](http://localhost:3000) to see the main
page. There is a small extract of data but the interesting part is the API.

### API

Alaska doesn't return you the entire model from Certstream for the moment. It
creates a simpler model that focuses on threat hunting (and can and/or will be improved):

```go
type Certificate struct {
	gorm.Model
	Aggregated  string `json:"aggregated"`
	C           string `json:"C"`
	ST          string `json:"ST"`
	L           string `json:"L"`
	O           string `json:"O"`
	OU          string `json:"OU"`
	CN          string `json:"CN"`
	Fingerprint string `json:"fingerprint"`
}
```

#### /api/certs

Returns 100 random certs from your database.

#### /api/certs/:name

This will run a search on the CN field or the fingerprint field and return you a
possible result.
