* Complies with RFC 4253, 4252, and 4254. * Implements the SSH-2 protocols. This means that data exchanges with the server use strong encryption and data integrity checks. Encryption keys are exchanged in a secure manner and are automatically changed periodically during a session. * Implements versions 3 and 6 of the SFTP protocol. Versions 4 and 5 are not supported but automatic fallback to version 3 works with most servers. * Items from the SFTP server are represented by SFtpFile and SFtpFolder objects, allowing them to be manipulated like regular files and folders. These classes integrate with Xceed’s FileSystem component. * Unlike FTP, SFTP enforces a precise date and time format (down to the second for version 3 servers and down to the nanosecond for version 6 servers). This makes it easy and consistent to determine the freshest file between client and server machines. * Supports HTTP, SOCKS4/4A and SOCKS 5 proxy servers. * Efficient flow control. * Supports encryption methods based on the counter mode of operation (aes256-ctr, etc) for increased interoperability. * Also supports arcfour encryption algorithms. * Specify which network adapter to connect from if the system is using multiple network adapters.100% managed code written in C#. * Source code available through a Blueprint subscription.
