How do I find my SSH RSA host key?

To generate an SSH key on your Linux server run the command ssh-keygen . The command can take flags if you would like to customize the type of key that is generated as well as the signing algorithms used to generate the key. This example generates a standard 2048-bit RSA key without a passphrase.

What is host key algorithm in SSH?

Host key algorithms specify which host key types are allowed to be used for the SSH connection. The first host key entered in the CLI is considered a first priority. Each option represents a type of key that can be used. Host keys are used to verify the host that you are connecting to.

What is an RSA host key?

A host key is a cryptographic key used for authenticating computers in the SSH protocol. Host keys are key pairs, typically using the RSA, DSA, or ECDSA algorithms. Public host keys are stored on and/or distributed to SSH clients, and private keys are stored on SSH servers.

What type of RSA key for SSH?

SSH keys are of three types- RSA, DSA and ECDSA. OpenStack supports RSA keys as RSA is more universal than DSA and ECDSA. Tip: Platform9 supports all RSA key lengths, that is, 1024, 2048, and 4096. The recommended RSA key length is 2048.
