Built for reliability
Verify licenses with a secure public key and ensure validity without an internet connection.
A signed JWT with license data is generated and the client stores it locally. Even offline, the license token can be cryptographically verified using a public key.
To ensure the client has the latest license information, the token needs to be refreshed periodically. When the device is online, it can refresh its token by requesting a new one from the Keyforge API.
You can customize for how long a token is valid. For very long offline periods, you can skip expiration checks if needed, but this is not optimal.
The offline licensing system is universal and can be implemented in any programming language that supports JWTs.
