use license key instead of file

[furesoft]

is it possible to use a licence key in this format instead of a file?
xxxx-xxx-xxxx-xxxx-xxx

I know this is kind of old...but for anyone else who might wonder...

What I did for this was simply to encrypt the license with AES. Created an application-specific Salt string that is used when encrypting the license. It's too long to expect a customer to type it in, but it can be sent in an email, then copy-n-pasted.

This sounds interesting.
Do you have a sample of this?
