Secure Shell
delete public-key
This command deletes the specified user’s public key.
Syntax
delete public-key username [dsa | rsa]
username – Name of an SSH user. (Range: 1-8 characters)
dsa – DSA public key type.
rsa – RSA public key type.
Default Setting
Deletes both the DSA and RSA key.
Command Mode
Privileged Exec
Example
Console#delete public-key admin dsa
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
Generates both the DSA and RSA key pairs.
Command Mode
Privileged Exec
Command Usage
• The switch uses only RSA Version 1 for SSHv1.5 clients and DSA Version 2 for SSHv2 clients.
• 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
Console#ip ssh crypto host-key generate dsa
Console#
