 Different from the old version, the Key in this version is mandatory. When hbbs runs for the first time, it will automatically generate a pair of encrypted private key and public key (respectively located in the `id_ed25519` and `id_ed25519.pub` files in the running directory), its main purpose is for communication encryption, if you did not fill in the Key in the previous step (the content in the public key file `id_ed25519.pub`),

 同上个版本不同，本版本中的Key是强制的，hbbs在第一次运行时，会自动产生一对加密私钥和公钥（分别位于运行目录下的`id_ed25519`和`id_ed25519.pub`文件中），其主要用途是为了通讯加密，如果您在上一步骤中没有填写Key(公钥文件`id_ed25519.pub`中的内容)，
