idk, my tool "vainstr" works pretty nice but isn't just a generator but a miner, lets you pick out some bech32 letter sequence that you want, beginning, end, or anywhere in the key, it can make a key like mine with "mleku" at the end in about 10 minutes on a 12 core ryzen 5. you can of course just get one instantly with just one chosen letter like 1 or something

nak from fiatjaf is a good tool for making events from the CLI, mattn's algia is a nice tool for publishing events too 

 thank you, I’ll give these a try!

 npx noskey

then nostril or nak 

 actually i just realized there is no best way, pretty much nothing works, because many tags require 3 properties (unfortunately), and i dont know a way to do that

after asking around i ended up having to write my own 

 For the nsec[...]
nak key generate | nak encode nsec

For the npub[...]
nak key public [paste nsec] | nak encode npub

The nsec and npub can be converted back to hex with

nak decode npub [key]
nak decode nsec [key] 

 this is just what I needed, thanks! 

 No prob 😊
