The original ftp protocol is flawed since data is not encrypted, meaning that user verification information can be intercepted. This secure FTP client provides full support for Shell Access, FTPS (File Transfer Protocol using SSL), SFTP (Secure File Transfer Protocol) and other protocols, without requiring additional installation or a connection to external libraries. Thus, all data traffic is encrypted so that login information cannot be intercepted. FTP program includes all current security standards, such as SSL, TLS, SSH, PGP, and password encryption. It supports multithreading data transfer, folder and file synchronization, scripting, and 128-256 bit encryption. In addition to its many security features, the highly functional file transfer client also has a number of usability enhancements that are rarely available in similar packages. Functions include the ability to recover interrupted downloads, connect to a server using special commands to prevent disconnect, compare and synchronize directories in different time zones, track buffer exchange, and transfer files larger than 1 GB. The client also provides support for proxy, firewalls, SOCKS 4, 4.5 and 5. A convenient download speed indicator and a built-in task scheduler enhance the user’s experience and maximize file-transfer flexibility.
