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).
However, for additional security the private key itself can be locked with a passphrase. The private key can also be looked for in standard places, and its full path can be specified as a command line setting (the option -i for ssh). The ssh-keygen utility produces the public and private keys, always in pairs.
The SSH client and key agent are enabled and available by default, and the SSH server is an optional Feature-on-Demand. [21] In October 2019 protection for private keys at rest in RAM against speculation and memory side-channel attacks were added in OpenSSH 8.1. [22]

Bitvise is a proprietary secure remote access software developed for Windows and available as a client and server. [3] The software is based on the Secure Shell (SSH) protocol, which provides a secure channel over an insecure network in a client-server architecture. [4]
An SSH client is a software program which uses the secure shell protocol to connect to a remote computer. This article compares a selection of notable clients. This article compares a selection of notable clients.
