SSH Encryption

SFTP stands for "SSH File Transfer Protocol." Like its name suggests, it is a file transfer protocol (similar to FTP) that operates inside an SSH (secure shell) session. The SSH protocol, and by extension Robo-FTP's implementation of SSH/SFTP, offers a number of encryption and encryption-related features to ensure the security of your data. When an initial connection is established to the server, both client and server must agree to use the same ciphers and algorithms.
