To create a connection, call the class using these arguments: host, user, passwd, acct, timeout, source_address, encoding The first four arguments are all strings, and have default value ''. The parameter ´timeout´ must be numeric and defaults to None if not passed, meaning that no timeout will be set on any ftp socket(s). If a timeout is passed, then this is now the default timeout for all ftp socket operations for this instance. The last parameter is the encoding of filenames, which defaults to utf-8. Then use self.connect() with optional host and port argument. To download a file, use ftp.retrlines('RETR ' + filename), or ftp.retrbinary() with slightly different arguments. To upload a file, use ftp.storlines() or ftp.storbinary(), which have an open file as argument (see their definitions below for details). The download/upload functions first issue appropriate TYPE and PORT or PASV commands. rNTFutf-8encodingcCs>||_||_||_|r|||r||||dSdSdS)zInitialization method (called by class instantiation).

Connect as usual to port 21 implicitly securing the FTP control connection before authenticating. Securing the data connection requires user to explicitly ask for it by calling prot_p() method. Usage example: >>> from ftplib import FTP_TLS >>> ftps = FTP_TLS('ftp.python.org') >>> ftps.login() # login anonymously previously securing control channel '230 Guest login ok, access restrictions apply.' >>> ftps.prot_p() # switch to secure data connection '200 Protection level set to P' >>> ftps.retrlines('LIST') # list directory content securely total 9 drwxr-xr-x 8 root wheel 1024 Jan 3 1994 . drwxr-xr-x 8 root wheel 1024 Jan 3 1994 .. drwxr-xr-x 2 root wheel 1024 Jan 3 1994 bin drwxr-xr-x 2 root wheel 1024 Jan 3 1994 etc d-wxrwxr-x 2 ftp wheel 1024 Sep 5 13:43 incoming drwxr-xr-x 2 root wheel 1024 Nov 17 1993 lib drwxr-xr-x 6 1094 wheel 1024 Sep 13 19:07 pub drwxr-xr-x 3 root wheel 1024 Jan 3 1994 usr -rw-r--r-- 1 root root 312 Aug 1 1994 welcome.msg '226 Transfer complete.' >>> ftps.quit() '221 Goodbye.' >>> rNrrc  s|dur |dur td|dur|durtd|dus |dur+ddl} | dtd||_||_|dur>tj|j||d}||_ d|_ t j |||||| | ddS) Nz4context and keyfile arguments are mutually exclusivez5context and certfile arguments are mutually exclusiverzAkeyfile and certfile are deprecated, use a custom context insteadr)certfilekeyfileFr) r2warningswarnDeprecationWarningrrsslZ_create_stdlib_context ssl_versioncontext_prot_psuperr#) rrr r!r"rrrrrrr __class__rrr#s* zFTP_TLS.__init__Tcs*|r t|jtjs |t|||Sr$)rr'r SSLSocketauthrr)rr r!r"Zsecurerrrrsz FTP_TLS.logincCsft|jtjr td|jtjkr|d}n|d}|jj |j|j d|_|jj d|j d|_ |S)z2Set up secure control connection by using TLS/SSL.zAlready using TLSzAUTH TLSzAUTH SSLZserver_hostnamer0)moder)rr'rrr2rZ PROTOCOL_TLSrwr wrap_socketrr9rr:rjrrrrs   z FTP_TLS.authcCs0t|jtjs td|d}|j|_|S)z/Switch back to a clear-text control connection.z not using TLSZCCC)rr'rrr2rwrrjrrrcccs   z FTP_TLS.ccccCs|d|d}d|_|S)zSet up secure data connection.zPBSZ 0zPROT PTrwrrjrrrprot_ps zFTP_TLS.prot_pcCs|d}d|_|S)z"Set up clear text data connection.zPROT CFrrjrrrprot_cs zFTP_TLS.prot_ccs2t||\}}|jr|jj||jd}||fS)Nr)rrrrrr)rrtrrrrrrrs zFTP_TLS.ntransfercmdcCs8dt}|j||}|dddvrt||S)Nrlr^rm)rnr'rRrbrrprrrrqs  z FTP_TLS.abort)rrrTr$)rrrrrZPROTOCOL_TLS_CLIENTrrr#rrrrrrrq __classcell__rrrrrs   rcCs\|dddkr t|tdurddl}|d|j|jBat|}|s'dSt|dS)zParse the '150' response for a RETR request.
