crypto ssh-key generate
Regenerate public keys used in SSH authentication.
Syntax
crypto ssh-key generate {rsa bits | ecdsa bits | ed25519}
Parameters
● rsa bits — Regenerates the RSA key with the specified bit size (2048, 3072, or 4096; default
2048).
● ecdsa bits — Regenerates the ECDSA key with the specified bit size (256, 384, or 521; default
256).
● ed25519 — Regenerates the Ed25519 key with the default bit size.
Default The SSH server uses default public key lengths for client authentication:
● RSA key: 2048 bits
● ECDSA key : 256 bits
● Ed25519 key: 256 bits
Command Mode EXEC
Usage
Information
If necessary, you can regenerate the public keys used by the SSH server with a customized bit size. You
cannot change the default size of the Ed25519 key. The crypto ssh-key generate command is
available only to the sysadmin and secadmin roles.
Example
OS10# crypto ssh-key generate rsa 4096
Host key already exists. Overwrite [confirm yes/no]:yes
Generated 4096-bit RSA key
