How to Install OpenSSH Server on Alpine Linux

OpenSSH server is an implementation of the SSH protocol, which comes with a collection of networking utilities based on the SSH protocol. The SSH protocol is a secure protocol that encrypts all traffic exchanged between a client and remote host using strong encryption methods.
