Console#

ip ssh crypto host-key generate

This command generates the host key pair (i.e., public and private).

Syntax

ip ssh crypto host-key generate [dsa rsa]

dsa – DSA (Version 2) key type.

rsa – RSA (Version 1) key type.

Default Setting

Command Mode

Privileged Exec

Command Usage

This command stores the host key pair in memory (i.e., RAM). Use the ip ssh save host-keycommand to save the host key pair to flash memory.

Some SSH client programs automatically add the public key to the known hosts file as part of the configuration process. Otherwise, you must manually create a known hosts file and place the host public key in it.

The SSH server uses this host key to negotiate a session key and encryption method with the client trying to connect to it.

Example

Console#ip ssh crypto host-key generate dsa

Console#
