Wallet sign in for games

[Nighty13]

The problem that you wish to solve

Hello ,
currently im trying to push cardano integration for games as much as possible & see how far i can go .
so the idea is the player download Daedalus , launch the game & he will be able to see & connect to his Wallets ( locally game will connect to cardano-wallet & use same Daedalus DB)... all cool to this point , you can sign transactions & do a lot of stuff..
but the moment i tried to implement a sign in , i got stuck ..

NOTE : this is Desktop C++ App ... icant use web based wallets etc ...( as many suggested to me ) .

Description

is there a way to use cardano-wallet to do "message signing" & "verification" (just like today browser wallets do)? so i can verify that the player is truely the owner of x wallet without firing a transaction ..

Implementation suggestions

Hi @Nighty13 - thanks for this!

I agree, this would a message signing feature is something we should support in cardano-wallet. Do you also require a means of verifying a signed message in the wallet? 😄

Indeed both sign and verify , currently i looked into libraries built on top of cardano-wallet ( like cardano-wallet-js and others ) they do handle the message signing themselves everytime .. . having such a feature built into cardano-wallet will be a life saver.
