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

ip ssh crypto host-key generate [dsa | rsa]

• dsa – DSA (Version 2) key type. 
• rsa – RSA (Version 1) key type. 

Generates both the DSA and RSA key pairs.

Privileged Exec

• This command stores the host key pair in memory (i.e., RAM). Use the 

ip ssh save host-key command 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.
