practice 1. verifying the GPG Suite
  1. found the public key in https://keybase.io/gpgtools and it's the same as the one showing in the site foot.
curl https://keybase.io/gpgtools/pgp_keys.asc | gpg --import
Imported the key and marked full trust.
  1. verified the signature file.

but it's showing one of the expired keys, I think it still meant the file is OK.
  1. verified the hashes.

well, it needs to start with verifying the tool before verifying other things. 🤓
and in this case, the software didn't sign too? and how can I tell is it sign or not? ( when do I need to do the sha256sum --check step )
