say FileZilla have FTPS (FTP over SSL) and secure-FTP (FTP over SSH)

So why cant we borrow it, just like we did for FTP
Sure, we can. It just means to integrate OpenSSL into WinSCP. Which means bloat of binary size :-(

Why not consider a plugin style architecture for WinSCP, with a strip down stand alone exe file. And the install version should come with other protocol like FTP, FTPS, WebDAV.

I have thought about it too. But I like the fact WinSCP is just a single file that works as is.

Hi,
I just upgraded from 3.8 to 4.0.7 as I found out that it supports FTP, too, now. This is great because the FTP client I used before always nagged me with a "License reminder" and expired from time to time forcing me to an upgrade. ;) Sadly WinSCP doesn't support FTP/SSL yet which keeps me from recommending it to my clients as FTP client. I already do recommend it as SFTP client though.

You say OpenSSL would bloat the binary. By how much? My 3.8 binary is 1.2 MB, the 4.0.7 binary is 4.8 MB. PHP's OpenSSL DLLs are 1.4 MB. I don't think that would hurt too much considering the current size increase already.

EXE size of 3.8 was 4.0 MB. You refer to compressed standalone binary, which is 1.25 MB in 4.1.

Ah, okay, I just looked at what I found on my disk. Right, I had a single binary before and now used the multi-language installer.

Does WinSCP Support Implicity SSL connection or not?

2008-06-03 20:15

Hi,

I am trying send a file through SFTP to a destination. But they say that I will be able to send out file only if my software has Implicity SSL/SSO Connection enabled.

I am using WinSCP and please help me how can I send out the file. Your prompt response would be greatly appreciated.

Thanks in advance.

WinSCP does not support SSL at all.

Hello Martin,
thanks for your great work!

I would really like to see this feature in WinSCP!

I have to use FileZilla for some of my projects, but I don't like it half as much as your program.

PS: I would also appreciate a Linux version. ;-)

what do you suggest best ftps client since winscp doesn't even support ftps becuase size will inceased?
Better a client with more protocol supports that some MO more size.

I really like your tool, but this is required in my environment so it would be great to have.

THANK YOU!

2009-03-02 23:58

First I want to say thanks for
implementing this in v.4.2.1! :D

It works fine here!

Question: Does FTP over explicit SSL
in WinSCP only encrypt the login and
password data or is also the file
transfer secured? Thanks :)

(I ask this because in SmartFTP it is
possible to secure the file transfer
and the login process separately).

Scripting on protocol SSL/TLS

2009-03-24 11:45

Hello,

I've just a simple question, because I didn't reach to find this information on the WinSCP website.
Is there a way to use scripts with this new functionnality on the protocol FTP with SSL/TLS ?
If yes what's the correct parameter to use / specify ?

Thanks for you job,

Best regards
Vincenzo

Not yet. This request is being tracked already.

Yet this FAQ will show you workaround.

I am trying to use FTP with TLS Explicit encryption to a proftpd server.
I am getting the following error from WinSCP

Retrieving directory listing...
TYPE A
200 Type set to A
PORT 192,168,1,7,16,69
200 PORT command successful
LIST
150 Opening ASCII mode data connection for file list
SSL connection established
425 Unable to build data connection: Operation not permitted
Could not retrieve directory listing

Here is the error log from the proftpd server

May 01 18:45:20 mod_tls/2.3[2419]: starting TLS negotiation on data connection
May 01 18:45:21 mod_tls/2.3[2419]: did NOT reuse SSL session for data connection
May 01 18:45:21 mod_tls/2.3[2419]: Client did not reuse SSL session, rejecting data connection (see TLSOption NoSessionReuseRequired)
May 01 18:45:22 mod_tls/2.3[2419]: unable to open data connection: TLS negotiation failed

Is there a setting that forces WinSCP to reuse the same SSL session?
Any ideas how I can fix this?
I really don't want to use FileZilla

WinSCP cannot reuse the SSL session. You may remove the requirement on the server-side as workaround.

FTP over explicit TLS/SSL

2011-02-10 01:40

Does WinScp support "FTP over explicit TLS/SSL" FTP protocol. I am using version 4.2.9(build 938)
If yes, how can I use it.
I was looking at the FTP dropdown and it has the following 4:-
1.No Encryption
2.SSL/TLS Implicit encryption
3.SSL explicit encryption
4.TLS explicit encryption

Thanks[/list]

You have to know if you need to use TLS or SSL. If you do not know, try TLS first.

Are you able to connect with any other FTP client? Do you have anyone to ask, what kind of connection you are supposed to use with that server?

2011-02-14 18:14

Yes, I can connect with Filezilla and Core FTP LE. Filezilla has the "FTP over explicit TLS/SSL" FTP Protocol.
In Core FTP LE, the setting is:
Connection Type: Auth SSL
SSL Options:- Checked SSL Listing, SSL Transfer, Open SSL
Checked PASV

I'm a different person than the OP trying to get FTPES FTP over explicit TLS/SLL working, but here are my logs.

I tried WinSCP with both Explicit TLS and Explicit SSL, no luck.. here are the logs

I really wanted to use WinSCP to automate.. but it looks like it won't work.

Hopefully this will help you add this feature..

I'm a different person than the OP trying to get FTPES FTP over explicit TLS/SLL working, but here are my logs.

I tried WinSCP with both Explicit TLS and Explicit SSL, no luck.. here are the logs

I really wanted to use WinSCP to automate.. but it looks like it won't work.

Hopefully this will help you add this feature..

Thanks for your post. This issue is being tracked already.

Thanks. I do not see anything wrong in the log files. May I have a test account on your server?

Hi Martin,

thanks for your effort. I'll found it on your tracker. I'm using your WinSCP a few years and this is the first problem i have with it. Really nice work! I'll do a donation for you soon.

Hey,

Any chance on supporting https://scarybeastsecurity.blogspot.com/2009/02/vsftpd-210-released.html now?

I know you mentioned above to turn it off server side.

I have and it works as mentioned.

But was hoping it could finally be supported now?

Thanks,

Will

And thanks for unbanning my account. Odd how it bans you if use a bad keyword in your post. Too strong of a spam filter it seems.

vsftpd-2.1.0 support

2011-07-12 11:36

Hello,

I just wanted to mention that I would need this feature as well. This is the only thing that forces me to use FileZilla (whose interface I don't like) parallely to WinSCP.

So while Chris Evans thinks not many people need FTP over SSL I need it because my webhoster offers no other secure connection methods.

reuse SSL session

WinSCP cannot reuse the SSL session. You may remove the requirement on the server-side as workaround.

Hi, pls, do you plan to add support for reusing? "Server side workaround" sounds horribly :).

In some situations is this workaround impossible and is feel as security flaw by my clients.

Hi Martin,

i´ve still got this problem.

Here are the part from my logfile where i loose the TLS-connection:

. 2015-08-03 15:32:12.547 Trying reuse main TLS session ID

. 2015-08-03 15:32:12.573 Session ID reused
. 2015-08-03 15:32:12.573 TLS layer changed state from connected to aborted
. 2015-08-03 15:32:12.573 Disconnected from server
. 2015-08-03 15:32:12.573 Data connection closed

. 2015-08-03 15:32:12.573 Got reply 1004 to the command 2
. 2015-08-03 15:32:12.573 Ignoring old TransferEnd message
. 2015-08-03 15:32:12.573 Connection was lost, asking what to do.
. 2015-08-03 15:32:12.573 Asking user:
. 2015-08-03 15:32:12.573 Lost connection. ("Disconnected from server","Could not retrieve directory listing")
* 2015-08-03 15:32:15.408 (ESshFatal) **Lost connection.**
* 2015-08-03 15:32:15.408 Disconnected from server

Hi Martin,

now we´ve solved the problem by using the option TLSOptions NoSessionReuseRequired at the server-config.

Maybe you can find a workaround for this issue if someone cannot change his configuration on the server.
