If you remember the “glory days” pre ubiquitous constant internet connections, you had to enter a big long code when installing any software. I think the principle is that the license key is some sort of decryption key that unlocks a core part of the software which would otherwise prevent it running.

I do! I see okay, so it’s like the private key is stored within the ROM somewhere, and that activation code is like a public key that just decrypts based on the locally stored private key, making anti-piracy software work whether online or offline. Quite clever, really! Thanks 😊
