Command Usage
• 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.
Example
ip ssh crypto zeroize
Use this command to clear the host key from memory (i.e. RAM).
Syntax
ip ssh crypto zeroize [dsa | rsa]
• dsa – DSA key type.
• rsa – RSA key type.
Default Setting
Clears both the DSA and RSA key.
