SSH bằng cách kiểm tra tên người dùng / mật khẩu hoặc khóa công khai rằng khách hàng đã xuất trình để chứng thực. Quá trình này được mã hóa hoàn toàn. Nếu máy chủ SSH xác thực khách hàng và khách hàng được ủy quyền, phiên SSH bắt đầu giữa hai thực thể.

Fields such as VerboseMode QuietMode Compression GoBackground and EscapeChar allow customized generic settings to be enabled from the profile file itself instead of typed into the command line. Some of the selected fields in the General section are provided in Table as well as a brief description of each. Network The Network section of the configuration file lists networking settings required for the connection.

Table gives a brief description of some of the selected fields in the Network section.
