WS_FTP Professional 2006 is one of the most secure ways to transfer files. This mature FTP client includes advanced security (SSL, SSH and PGP) and file management -- everything you would expect from an FTP client. In addition, security and transfer options now provide up to 256-bit encryption and support for HTTP and HTTPS transfers; there’s also OpenPGP public key/private key encryption, extensive protocol support, email notifications and a new compression utility that allows you to zip and unzip files on the fly.
