implicit ftp - SSL problem

[SharpCoderMP]

hi,

i've found out here:
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=131195&SiteID=1
that FtpWebRequest does not support implicit connections. I have a
serious problem with that, because i need to talk to an Ftp server that
supports only the explicit connections. changing the server is out of
question. and i need ssl to keep login and password secure. to make
things worse i can only log in using ssl. then i need to use Clear Data
channel.

does anyone have any ideas what to do? i didn't dig too deep into this
but is it possible to implement the explicit ssl without rewriting the
whole FtpWebRequest class?

sorry guys, of course i meant *implicit* here

to make things clear: i need implicit ssl implementation.

If you really want to do this, your best bet is to write it as an FTP
proxy - but then, why not just buy an implicit SSL FTP proxy, which is far
cheaper than writing it, and use that?

While I'm here, I might as well note that implicit SSL FTP has been
deprecated for well over a year, and was deprecated well before the FTP over
SSL / TLS specification became an official RFC document. Supporting
implicit SSL FTP is a bad idea. It was a dead end before it got started.

if so, i can as well buy a third party secure ftp component for .net and
use it instead of FtpWebRequest introduced in 2.0 framework.

you are probably right but unfortunately i can not change the ftp server
