ssh server algorithm

Configures the SSH server host key algorithm to be used for X.509v3 certificate-based SSH authentication (server authentication).

Syntax

ssh server algorithm {hostkey {x509v3-ssh-rsa | x509v3-rsa2048-sha256}}

no ssh server algorithm hostkey

The host key algorithm is not configured.

hostkey {x509v3-ssh-rsa | x509v3-rsa2048-sha256}: Designates x509v3-SSH-RSA or x509v3-RSA2048-SHA256 as the host key algorithm.

Global configuration mode

Use the no form of the command to remove the configured algorithm.

This example configures x509v3-SSH-RSA as the host key algorithm.

device# configure terminal
device(config)# ssh server algorithm hostkey x509v3-ssh-rsa
