How to use

Prerequisites

• MongoDB server

Start f-license server

1. Create and configure config.json file like sample_config.json
2. Run go build
3. Run ./f-license

Embed client code to your app

If your app's language is Go , you need to add just one line code to your application after importing client .

import "github.com/furkansenharputlu/f-license/client"

Remote verification

verified, err := client.VerifyRemotely("https://localhost:4242", "trusted-server-cert", "license-key")

Local verification

verified, err := client.VerifyLocally("secret-or-public-key", "license-key")

If you are not using Go , you can easily implement their equivalent in your app's languge for now. In future, we will implement for different languages.

CLI usage

1. Run go build -o f-cli ./cli
2. Generate license.json like sample_license.json
