Sterling B2B Integrator is compatible with most SFTP clients and SCP clients. The following clients have been tested and approved for interoperability with the SFTP Server adapter: Sterling Connect:Enterprise ® Secure Client (version 1.3.00) Sterling Connect:Enterprise ® Command Line Client (SFTP protocol version 3) OpenSSH (version sftp). SFTP – should only be used for SFTP, the SSH file transfer protocol. Unfortunately, people often shorten Secure FTP into SFTP - this is incorrect, because the S in SFTP stands for SSH, not for Secure. SFTP2 – this confusing name is used by some vendors to highlight the obvious fact that their SFTP protocol runs over SSH2. For all practical. SFTP stands for SSH File Transfer Protocol or Secure File Transfer Protocol. It is a protocol used to transfer files between remote machines over a secure shell. In almost all cases, SFTP is preferable over FTP because of security features. FTP is not a secure protocol & it should only be used on a trusted network. Choosing Library for C#.
SFTP has pretty much replaced old FTP and FTPS on internal networks and in any security-critical applications. Some anonymous FTP usage remains for public access, and some legacy equipment still uses FTP. FTPS has remained a curiosity, supported. Client did not verify SSH host keys or FTPS certificates: Interarchy: Mac: SSH (SFTP) worked, FTPS did not work: Syncplify.me FTP! 1.0.11.31: Windows: SSH (SFTP) worked, FTPS did not work because it did not support TLS for data connections: Sysax FTP Automation: 1.0.11.31: Windows: SSH (SFTP) worked, FTPS did not work because it did not support.
FTPS (also known as FTP Secure and FTP-SSL) is an extension to the commonly used File Transfer Protocol (FTP) that adds support for the Transport Layer Security (TLS) and the Secure Sockets Layer (SSL) cryptographic protocols.1
- Methods of Invoking
Two separate methods were developed to invoke client security for use with FTP clients: Explicit or Implicit. The former method is a legacy compatible implementation where FTPS aware clients can invoke security with an FTPS aware server without breaking overall FTP functionality with non-FTPS aware clients. The latter method is an incompatible method that requires clients to be FTPS aware. WinSCP supports both methods.
In explicit mode, a FTPS client must 'explicitly request' security from a FTPS server and then step-up to a mutually agreed encryption method. If a client does not request security, the FTPS server can either allow the client to continue insecure or refuse/limit the connection.
In Explicit Mode, the client has full control over what areas of the connection are to be encrypted. Enabling and disabling of encryption for the FTPS control channel and FTPS data channel can occur at any time. WinSCP though requests encryption for both control and data channel unconditionally during whole session.
Negotiation is not allowed with implicit FTPS configurations. A client is immediately expected to challenge the FTPS server with a connection encrypted using TLS/SSL. If it does not, the server should drop the connection.
In order to maintain compatibility with existing non-TLS/SSL aware FTP clients, implicit FTPS was expected to listen on the IANA Well Known Port 990/TCP for the FTPS control channel and 989/TCP for the FTPS data channel. This allowed administrators to retain legacy compatible services on the original 21/TCP FTP control channel.
In Implicit Mode, the entire FTPS session (both control and data channels) is unconditionally encrypted.

Migrating to SFTP isn't as hard as you think, and it's well worth the increased security.
There are plenty of businesses that are still using FTP and FTPS.
But in today's world, where hacks are a dime a dozen, it makes sense to increase security wherever you can.
Making the switch from FTP or FTPS to SFTP is a relatively easy way to increase the security of your file transfers, and this post will show you how.
Why should you move from FTP or FTPS to SFTP?
We get it – you're very comfortable with your current FTP file transfer setup.
You're probably using an easy desktop client like FileZilla, WinSCP, or CyberDuck. All you have to do is click a few buttons and voila – your files get where they need to be.
While FTP is very easy to use, its biggest drawback is poor security.
Usernames, passwords, and files are all sent in plain text, so your data is very susceptible to being intercepted and recognized.
Additionally, FTP requires a range of ports to remain open and publicly accessible for its data channel to be created, thus potentially leading to more security issues.
FTPS layers on a bit more security by adding support for Transport Layer Security (TLS) and its predecessor, Secure Sockets Layer (SSL). But it still suffers from having to open a range of ports.
SFTP is a much better option.
Usernames, passwords, and files are encrypted using Secure Socket Shell (SSH) so hackers won't be able to see all of your information.
You can also use key-based authentication for increased security (which we totally recommend). Or you can even combine key-based authentication with usernames and passwords for even more security.

And SFTP only uses one server port connection to transfer data, further increasing security and compliance with firewalls.
Also, you can obtain more metadata, such as date, time, and size, about the files being transferred.
SFTP takes a little bit of work to set up and manage. But we believe the increase in security is worth it, and there are now ways to set up SFTP servers easily.
What you don't need to change when moving to SFTP
Do you enjoy using FileZilla or WinSCP to move your files? Good! You can still use your desktop FTP client even if you migrate to SFTP.
All you need to do is launch an SFTP server, connect it to your desktop file transfer software, and you're off to the races!
Options for launching an SFTP server
The process of setting up an SFTP server will be different depending on the operating system that you're using and the desired destination of your files.
There are some great tutorials that teach you how to deploy an SFTP server, so we won't recreate the wheel here.
If you want to set up a local SFTP server and you're using Linux, check out this article. If you're on Windows, refer to this article from the folks at WinSCP.
You can also spin up a cloud SFTP server. Check out this tutorial to learn how.
If you're looking to launch a cloud SFTP server to push files to cloud storage, our products – SFTP Gateway for AWS and SFTP Gateway for Azure – help you do so easily (GCP version coming soon!). Check out these products if you're interested in transferring files to Amazon S3 and Azure Blob Storage, respectively.
How to connect your desktop FTP client to your SFTP server
The next step is to connect your desktop FTP software to the SFTP server you just deployed.
We'll walk you through how to do so with two of the most popular FTP clients – FileZilla and WinSCP.
How to connect FileZilla to your SFTP server
Gobdocuments 1 6 equals. FileZilla is one of the most popular desktop FTP clients, and the product is easy to configure to transfer files via the SFTP server you just set up.
Setup for other FTP clients like Cyberduck, Transit, and others should be similar.
Here are the steps to take to connect FileZilla to your SFTP server:
- Open FileZilla and navigate to File > Site Manager
- Click on New Site
- Name your site, if you'd like
- In the Host field, enter your public IP address
- Change the Protocol field to SFTP – SSH File Transfer Protocol
- If you're using password authentication:
- Change Logon Type to Normal
- Enter the end user's username and password into the respective fields
- If you're using SSH key authentication:
- Change Logon Type to Key file
- In the User field, enter the username you created when you deployed your SFTP server
- In the Key file field, browse for the .pem file that you created when deploying your SFTP server
- Click Connect and you're good to go!

How to connect WinSCP to your SFTP server
WinSCP is one of the most popular FTP clients for Windows users. The process of connecting WinSCP to an SFTP server is similar if you're using password authentication, but is a bit different if you're using key authentication.
Here are the steps to connect to your SFTP server with WinSCP:
- Navigate to the Login screen
- Change the File Protocol field to SFTP
- In the Host name field, enter your public IP address
- If you're using password authentication:
- Enter the end user's username and password into the respective fields
- If you're using key authentication:
- Copy the contents of your SSH key (including the –BEGIN and –END headers) into a new notepad file named private.txt.
- Enter your username in the User name field.
- Leave the Password field blank.
- Click on Advanced… > SSH > Authentication.
- For the Private key file field, change the drop-down to All Files (*.*), and open the private.txt file you created earlier.
- Click Open
- You should see a pop up that says Do you want to convert this OpenSSH private key to PuTTY format?
- Click OK and then Save. This will generate a .ppk formatted key.
- Click Login and you're good to go!
Conclusion
You don't have to change much if you move from FTP to SFTP.
You'll have to launch an SFTP server, then you can connect the desktop FTP client you're already using to it.
A little bit of setup work gets you much stronger security.
