Why Rebex FTP/SSL
Connect, log in, download a file, disconnect. Upload all text files in a folder at once.
It's easy to start developing
with our library.
Simple code for common use cases.
Login with... anything
Login using a username and password? Check.
Login with username/password/account? Check.
Login using X509 client certificate? Check.
File and directory operations made easy
Upload a file from the filesystem or memory. Rename and move files.
Check existing files. Or perform other
single file FTP operations.
transfer many files at once.
Upload and download whole directory structures.
Use wildcards or file sets to specify which files to transfer.
Monitor transfer progress with events.
work with directories?
List their content, create or rename them. You can even delete
non-empty folders recursively (and handle symlinks properly) using a single line of code.
Secure file transfers
Rebex FTP/SSL supports both plain FTP and FTP secured with
TLS/SSL. This protocol ensures that the file transfers are secure and reliable.
Rebex FTP/SSL supports both
implicit or explicit TLS/SSL
and provides a rich set of security features. You'll find APIs for TLS/SSL security,
X509 certificates, and more.
Powerful directory listing parser
The original FTP standard defined no standard directory listing format.
As a result, listings used by different FTP server on different operating
system are very diverse.
Fortunately, you don't have to worry about this with Rebex FTP/SSL.
It's reliable listing parser has been under continuous development since 2003
and can detect and parse virtually any
common directory listing format used by Unix, Windows, Netware, DOS, VMS, IBM 4690 or Tandem Guardian FTP servers.
Even if you come across a rare format which is not yet supported out-of-the-box,
can still easily add your own
custom directory listing parser.

Hear from customers
It took me 10 minutes to plug it into our C# application and voila,
passive FTP connections, excellent communication and error codes / messages when things don’t connect properly via our VPN.
Well done on an excellent product. I’m a software developer of some 18 years and I’m quite sceptical of 3rd party components, however, this FTP library is excellent. Can’t fault it.
I can Highly Recommend it.
