FTP_TLS
- FTP_TLS(host='', user='', passwd='', acct='', *, context=None, timeout=None, source_address=None, encoding='utf-8')
A FTP subclass which adds TLS support to FTP as described
in RFC-4217.
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

Changed in 3.3, 3.4, 3.9, 3.12
- 3.3: Added the source_address parameter.
- 3.4: The class now supports hostname check with ssl.SSLContext.check_hostname and Server Name Indication (see ssl.HAS_SNI).
- 3.9: If the timeout parameter is set to be zero, it will raise a ValueError to prevent the creation of a non-blocking socket. The encoding parameter was added, and the default was changed from Latin-1 to UTF-8 to follow RFC 2640.
- 3.12: The deprecated keyfile and certfile parameters have been removed.
