Blog post review about bitcoin-spring-boot-starter HOT 1 CLOSED

Hi!

Thanks again for your help.

Team effort 💪

I finished the blog post; Do you thing you could take a look at it before I publish it? I don't want people to get the wrong idea about your project. https://github.com/royllo/explorer/blob/development/docs/design/lnurl-auth/README.md

Looks good! So nice!

Maybe a hint that the module is actually still in "incubator" mode.
I want to make it a first class citizen once the "default login page" can be customized (currently, it is basically uncustomizable).

I have one last question:

K1 exchange I read in the documentation that the wallet will call the server URL login with this: sig=<hex(sign(utf8ToBytes(k1), linkingPrivKey))>&key=<hex(linkingKey)>

From what I see, the server will receive the signed k& and the public linking key. How do you, on the server side, make the link between the k1 your provided and the signed k1 you received ?

In your quote you forgot <LNURL_existing_query_parameters> which includes the plain k1 value as well.
Of course, to verify the signature one needs the k1, sig and pubkey!
Maybe that is also worth adapting in the blog post!

So the called url actually includes tag, k1, sig, key and optionally action.
