-* host - scp remote host
-* port - scp remote port, default is `22`
-* username - scp username
-* password - scp password
-* passphrase - the passphrase is usually to encrypt the private key
-* protocol - The IP protocol to use. Valid values are `tcp`. `tcp4` or `tcp6`. Default to `tcp`.
-* fingerprint - fingerprint SHA256 of the host public key, default is to skip verification
-* timeout - timeout for ssh to remote host, default is `30s`
-* command_timeout - timeout for scp command, default is `10m`
-* key - content of ssh private key. ex raw content of ~/.ssh/id_rsa
-* key_path - path of ssh private key
-* target - target path on the server, must be a directory (**required**)
-* source - scp file list (**required**)
-* rm - remove target folder before upload data, default is `false`
-* strip_components - remove the specified number of leading path elements.
-* overwrite - use `--overwrite` flag with tar, overwrite existing files when extracting
-* tar_tmp_path - temporary path for tar file on the dest host
-* tar_exec - path to tar executable on the dest host. default is `tar`
-* tar_dereference - use `--dereference` flag with tar, follow symlinks; archive and dump the files they point to
-* use_insecure_cipher - include more ciphers with use_insecure_cipher (see [#15](https://github.com/appleboy/scp-action/issues/15))
