A few people have been setting up testnet masternodes using dashmate and the manual install documentation and come up with the question of how to generate BLS public/private key pairs. The `dashmate setup` command will do this for you, and the `bls generate` command also allows you to do it in Dash Core. Both of these products integrate BLS libraries, but since Dashmate is written in JavaScript, we can also just run the relevant few lines of code in a web browser and import the `bls-signatures` libraries provided by Chia Network to get the same functionality. Just click Run to get your keys:
