Python FTP-SSL / FTP-TLS: Verifying Public Certificate?

Question

I'm using Python 2.7.5 (not 3.X) and I need to verify a FTPS (FTP-TLS) public certificate. That is, I want to verify it against the standard certificate authority, not a custom key. (Similar to HTTPS.)

I see some options but I cannot get them to work: The FTP_TLS() class doesn't seem to offer the ability to verify certificates, unless I'm mistaken: class ftplib.FTP_TLS([host[, user[, passwd[, acct[, keyfile[, certfile[, timeout]]]]]]])

I've read into the certifi and also M2Crypto, but while I can connect and transfer using FTP/TLS, I can't seem to find a way to verify the certificate.

Also, I don't think I will be able to use the CURL libraries in this case :( Just a note.

Answer 2

The resource referenced by mcepl is no longer available over http, but only using https. https://heikkitoivonen.net/blog/2008/10/14/ssl-in-python-26

So much for 301 redirects.
