ssh-keygen command options description -b bits Specifies the number of bits in the key to create. The default length is 3072 bits (RSA) or 256 bits (ECDSA). -C comment Provides custom key comment (which will be appended at the end of the public key). -K Imports a private resident key from a FIDO2 device. -p
This output would be produced by a ssh-keygen -r host.example.com. command on the target server by reading the existing default SSH host key (Ed25519). [ 5 ] With the OpenSSH suite, the ssh-keyscan utility can be used to determine the fingerprint of a host's key; using the -D will print out the SSHFP record directly.

SSH is typically used to log into a remote computer's shell or command-line interface (CLI) and to execute commands on a remote server. It also supports mechanisms for tunneling , forwarding of TCP ports and X11 connections and it can be used to transfer files using the associated SSH File Transfer Protocol (SFTP) or Secure Copy Protocol (SCP).
The algorithm uses a key pair consisting of a public key and a private key. The private key is used to generate a digital signature for a message, and such a signature can be verified by using the signer's corresponding public key.

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]
