Creating Public-Private Key Pairs
To use a self-signed certificate or Certificate Signing Request (CSR) certificate for switch authentication,
you must generate a public-private key pair.
To create a public-private key pair, use the following command:
crypto generate key {admin | domain | eap | ssh | web} {128 | 512 | 1024 | 2048}
Choose the key length based on your need for security or to conform with your organization’s practices.
For example, the following command generates an administrative key pair of 1024 bits:
DWS-1008#
crypto generate key admin 1024
admin key pair generated
Some key lengths apply only to specific key types. For example,
128 applies only to domain keys.
SSH requires an SSH authentication key, but you can allow MSS to generate it automatically. The first
time an SSH client attempts to access the SSH server on a switch, the switch automatically generates
a 1024-byte SSH key. If you want to use a 2048-byte key instead, use the
crypto generate key ssh
2048 command to generate one.
Note: After you generate or install a certificate (described in the following sections), do not create the
key pair again. If you do, the certificate might not work with the new key, in which case you will need to
regenerate or reinstall the certificate.
Generating Self-Signed Certificates
After creating a public-private key pair, you can generate a self-signed certificate.
To generate a self-signed certificate, use the following command:
crypto generate self-signed {admin | eap | web}
When you type the command, the CLI prompts you to enter information to identify the certificate. For
example:
DWS-1008#
crypto generate self-signed admin
Country Name: US
State Name: CA
Locality Name: San Jose campus
Organizational Name: dlink
Organizational Unit: eng
Common Name: SW1
Email Address: admin@example.com
Unstructured Name: wiring closet 120
success: self-signed cert for admin generated
You
must
include a common name (string) when you generate a self-signed certificate. The other
information is optional. Use a fully qualified name if such names are supported on your network. The
certificate appears after you enter this information.
