Software components for data protection, secure storage and transfer

Add SSH and SFTP client and server functions to your Windows or Linux application

SecureBlackbox product diagram

Implement secure file transfers with SFTP components for Delphi.

The SFTP VCL allows building SFTP client and server applications for Windows, Linux, MacOS, iOS and Android, giving your applications the ability to securely download and upload files and manage files and directories in a secure manner. With SFTP components, your application will be able to perform a range of remote file operations over an SSH secured connection, including the ability to create, delete and rename files and directories on remote SSH servers, list directory structure. SFTPBlackbox includes implementations of both SSH and SFTP protocols, allowing developers to build SSH and SFTP servers and client applications.

The SFTPBlackbox package is an integral part of SecureBlackbox. Download SecureBlackbox (VCL edition) to implement SSH and SFTP protocols in Delphi to build client and server applications for Windows, Linux, MacOS, iOS and Android.

SFTP or FTPS Components?

Both SFTP and FTPS protocols help achieving essentially the same goal of securing file transfer operations. However, the two protocols are designed and implemented differently, and are not compatible or interchangeable. FTPS (FTP-over-SSL, RFC 2228) secures file transfer operations by establishing an FTP connection over a secure SSL/TLS tunnel, while SFTP (SSH File Transfer Protocol) is an extension of Secure Shell (SSH2) family of protocols.
As the two file transfer protocols are not interchangeable, you will be using different components to implement support for either or both protocols in your applications. SFTPBlackbox (this page) implements the SFTP protocol, while the FTPS protocol is implemented with a corresponding FTPS component, FTPSBlackbox. Both secure FTP components for Delphi are included with SecureBlackbox.
