A friendly Python SFTP interface.

class (host, username=None, private_key=None, password=None, port=22, private_key_pass=None, ciphers=None, log=False)¶

Connects and logs into the specified hostname. Arguments that are not given are guessed from the environment.

Parameters:	host (str) &#; The Hostname or IP of the remote machine. username (str|None) &#; Default: None - Your username at the remote machine. private_key (str|obj|None) &#; Default: None - path to private key file(str) or www.cronistalascolonias.com.arey password (str|None) &#; Default: None - Your password at the remote machine. port (int) &#; Default: 22 - The SSH port of the remote machine. private_key_pass (str|None) &#; Default: None - password to use, if private_key is encrypted. ciphers (list|None) &#; Default: None - List of ciphers to use in order. log (bool|str) &#; Default: False - log connection/handshake details?
