 ### Key
 
-Different from the old version, the key in this version is mandatory, but you don't need to set it yourself. When `hbbs` runs for the first time, it will automatically generate a pair of encrypted private and public keys (respectively located in the `id_ed25519` and `id_ed25519.pub` files in the running directory), whose main purpose is for communication encryption.

-If you want to prohibit users without the key from establishing non-encrypted connections, please add the `-k _` parameter when running `hbbs` and `hbbr`, for example:
-
-```sh

 If you want to change the key, remove the `id_ed25519` and `id_ed25519.pub` files and restart `hbbs`/`hbbr`, `hbbs` will generate a new key pair.
