ssh-keygen is a standard component of the Secure Shell (SSH) protocol suite found on Unix, Unix-like and Microsoft Windows computer systems used to establish secure shell sessions between remote computers over insecure networks, through the use of various cryptographic techniques. The ssh-keygen utility is used to generate, manage, and convert ...
Secure Shell (SSH) is a protocol allowing secure remote login to a computer on a network using public-key cryptography.SSH client programs (such as ssh from OpenSSH) typically run for the duration of a remote login session and are configured to look for the user's private key in a file in the user's home directory (e.g., .ssh/id_rsa).
SSH is typically used to log into a remote computer's shell or command-line interface (CLI) and to execute commands on a remote server. It also supports mechanisms for tunneling , forwarding of TCP ports and X11 connections and it can be used to transfer files using the associated SSH File Transfer Protocol (SFTP) or Secure Copy Protocol (SCP).
On Microsoft Windows, Remote Desktop Protocol can be used to provide GUI remote access, since Windows Vista, PowerShell Remote, since Windows 10 build 1809 SSH [4] can also be used for text-based remote access via WMI, RPC, and WS-Management. [5] Most operating system shells fall into one of two categories – command-line and graphical.
The OpenSSH suite includes the following command-line utilities and daemons: scp, a replacement for rcp. sftp, a replacement for ftp to copy files between computers. ssh, a replacement for rlogin, rsh and telnet to allow shell access to a remote machine.
The category Windows commands deals with articles related to internal and external commands ... Prompt (command) PROMPT (command) ... (command) Ssh-agent; Ssh-keygen;
the Telnet, rlogin, and SSH client itself, which can also connect to a serial port PSCP an SCP client, i.e. command-line secure file copy. Can also use SFTP to perform transfers PSFTP an SFTP client, i.e. general file transfer sessions much like FTP PuTTYtel a Telnet-only client Plink a command-line interface to the PuTTY back ends.
Perhaps the most widely used SCP program is the OpenSSH command line scp program, which is provided in most SSH implementations. The scp program is the secure analog of the rcp command. The scp program must be part of all SSH servers that want to provide SCP service, as scp functions as SCP server too.
