OS10# show crypto crl | Manually installed CRLs | Network_Solutions_Certificate_Authority.0.crl.pem | Downloaded CRLs | Request and install host certificates OS10 also supports the switch obtaining its own X.509v3 host certificate. In this procedure, you generate a certificate signing request (CSR) and a private key. Store the private key locally in a secure location. Copy the CSR file to a certificate authority. The CA generates a host certificate for an OS10 switch by digitally signing the switch certificate contained in the CSR. The administrator then copies the CA-signed host certificate to the home directory on the switch. Because a local private key is created when the CSR is generated, it is not necessary to install a private key using an uploaded file. The switch presents its own host certificate to clients that require authentication, such as Syslog and RADIUS servers over TLS and HTTPS connections. The certificate is digitally signed with the private key of the OS10 switch. OS10 supports multiple host certificates so that you can use different certificates with different applications. For more information, see Security profiles. To obtain a host certificate from a CA: 1. Create a private key and generate a certificate signing request for the switch. 2. Copy the CSR file to a CA server. 3. Copy the CA-signed certificate to the home directory on the switch. Install the trusted certificate. Generate a certificate signing request and private key ● Create a private key and a CSR in EXEC mode. Store the CSR file in the home directory or flash: so that you can later copy it to a CA server. Specify a keypath to store the device.key file in a secure persistent location, such as the home directory, or use the private option to store the key file in a private hidden location in the internal file system that is not visible to users. crypto cert generate request [cert-file cert-path key-file {private | keypath}] [country 2-letter code] [state state] [locality city] [organization organization-name] [orgunit unit-name] [cname common-name] [email email-address] [validity days] [length length] [altname alt-name] If you enter the cert-file option, you must enter all the required parameters, such as the local paths where the certificate and private key are stored, country code, state, locality, and other values. If you do not specify the cert-file option, you are prompted to fill in the other parameter values for the certificate interactively; for example: You are about to be asked to enter information that will be incorporated into your certificate request. What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank. For some fields there will be a default value; if you enter '.', the field will be left blank. Country Name (2 letter code) [US]: State or Province Name (full name) [Some-State]:California Locality Name (eg, city) []:San Francisco Organization Name (eg, company) []:Starfleet Command Organizational Unit Name (eg, section) []:NCC-1701A Common Name (eg, YOUR name) [hostname]:S4148-001 Email Address []:[email protected] The switch uses SHA-256 as the digest algorithm. The public key algorithm is RSA with a 2048-bit modulus. The KeyUsage bits of the certificate assert keyEncipherment (bit 2) and keyAgreement (bit 4). The keyCertSign bit (bit 5) is NOT set. The ExtendedKeyUsage fields indicate serverAuth and clientAuth. The attribute CA:FALSE is set in the Extensions section of the certificate. The certificate is NOT used to validate other certificates. 1170 Security
