SSH Encryption

Secure Shell (SSH) is a cryptographic network protocol meant to secure communications over an insecure connection between network devices. One of the ways SSH does this is by using public-key cryptography. SSH is most commonly used as a means for secure remote login and command execution, often in the context of a client-server interaction. SSH by default utilizes the standard TCP port 22, was originally designed to replace protocols like Telnet which sent data in plain-text form and file transfer protocols like SCP and SFTP are based on it.

This article will discuss and explore, among other things, the possible ways of creating SSH-keys, the underlying methods of encryption and some general best practices.
