Does aioftp support FTPES (FTP server over explicit TLS/SSL)

[saulcruz]

from ftplib import FTP_TLS

Using ftplib I was able to connect to my FTP server over explicit TLS/SSL in Python, I have not found a way to asynchronously download files using the aioftp library and FTPS. Does it only support plain FTP? If it supports FTPES would you please provide an example?

Update
I noticed that this feature was added #81

Does the same example in the README work? or are there any additional steps to connect to the FTP over explicit TLS/SSL ?

I'm getting the following error:
line 689, in do_handshake
ssl.SSLError: [SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:847)

import asyncio
import aioftp


async def get_mp3(host, port, login, password):
    async with aioftp.ClientSession(host, port, login, password, ssl=True) as client:
        for path, info in (await client.list(recursive=True)):
            if info["type"] == "file" and path.suffix == ".mp3":
                await client.download(path)


loop = asyncio.get_event_loop()
tasks = (
    get_mp3("server1.com", 21, "login", "password")),
    get_mp3("server2.com", 21, "login", "password")),
    get_mp3("server3.com", 21, "login", "password")),
)
loop.run_until_complete(asyncio.wait(tasks))
loop.close()

Thanks for this library :)

ssl=True just passed to open_connection. No magic (even no code at all 😄 ) here from aioftp library with ssl. So, yes, it works.

Interesting, not working for me :( not sure what is wrong or different in my server. It works when using fptlib and the FTP_TLS

from ftplib import FTP_TLS
ftps = FTP_TLS('ftp.python.org')
ftps.login() # login anonymously before securing control channel
ftps.prot_p() # switch to secure
ftps.retrlines('LIST')

explicit mode is not implemented, see #37

[pohmelie]

Oh, my bad. I misread "explicit". Only implicit mode supported right now. @rsichny, thanks!

[saulcruz]

Thanks @pohmelie and @rsichny will find a workaround then
