openssh-client - 1:7.9p1-10+deb10u2 main

This is the portable version of OpenSSH, a free implementation of
the Secure Shell protocol as specified by the IETF secsh working
group.
.
Ssh (Secure Shell) is a program for logging into a remote machine
and for executing commands on a remote machine.
It provides secure encrypted communications between two untrusted
hosts over an insecure network. X11 connections and arbitrary TCP/IP
ports can also be forwarded over the secure channel.
It can be used to provide applications with a secure communication
channel.
.
This package provides the ssh, scp and sftp clients, the ssh-agent
and ssh-add programs to make public key authentication more convenient,
and the ssh-keygen, ssh-keyscan, ssh-copy-id and ssh-argv0 utilities.
.
In some countries it may be illegal to use any encryption at all
without a special permit.
.
ssh replaces the insecure rsh, rcp and rlogin programs, which are
obsolete for most purposes.
