OPEN SSH

What is ? OpenSSH  is a free open source set of computer tools used to provide secure and encrypted communication over a computer network by using the  ssh  protocol. Many people, new to computers and protocols, create a misconception about  OpenSSH , they think it is a protocol, but it is not, it is a set of computer programs that use the  ssh protocol .
