Overview

The pki-server cert commands provides an interface to manage system certificates.

The commands take a certificate ID (sometimes also called certificate tag) instead of certificate nickname. Valid certificate IDs are:

  • ca_signing

  • ca_ocsp_signing

  • ca_audit_signing

  • kra_storage

  • kra_transport

  • kra_audit_signing

  • ocsp_signing

  • ocsp_audit_signing

  • tks_audit_signing

  • tps_audit_signing

  • sslserver

  • subsystem

The certificate IDs are always the same on any instance, for example a CA will always have a ca_signing, ca_ocsp_signing, ca_audit_signing, sslserver, and subsystem certificates regardless if the actual certificate nicknames.

Listing System Certificates

To list all certificates:

$ pki-server cert-find
  Cert ID: ca_signing
  Nickname: caSigningCert cert-pki-tomcat CA
  Token: Internal Key Storage Token
  Serial Number: 0x1
  Subject DN: CN=CA Signing Certificate,OU=pki-tomcat,O=EXAMPLE
  Issuer DN: CN=CA Signing Certificate,OU=pki-tomcat,O=EXAMPLE
  Not Valid Before: Tue Apr 03 23:15:43 2018
  Not Valid After: Sat Apr 03 23:15:43 2038

  Cert ID: ca_ocsp_signing
  Nickname: ocspSigningCert cert-pki-tomcat CA
  Token: Internal Key Storage Token
  Serial Number: 0x2

  Not Valid After: Mon Mar 23 23:15:44 2020

  Cert ID: ca_audit_signing
  Nickname: auditSigningCert cert-pki-tomcat CA
  Token: Internal Key Storage Token
  Serial Number: 0x5
  Subject DN: CN=CA Audit Signing Certificate,OU=pki-tomcat,O=EXAMPLE
  Issuer DN: CN=CA Signing Certificate,OU=pki-tomcat,O=EXAMPLE

Displaying System Certificate Info

To display basic certificate info:

$ pki-server cert-show ca_signing
  Cert ID: ca_signing
  Nickname: caSigningCert cert-pki-tomcat CA
  Token: Internal Key Storage Token
  Serial Number: 0x1
  Subject DN: CN=CA Signing Certificate,OU=pki-tomcat,O=EXAMPLE
  Issuer DN: CN=CA Signing Certificate,OU=pki-tomcat,O=EXAMPLE
  Not Valid Before: Tue Apr 03 23:15:43 2018
  Not Valid After: Sat Apr 03 23:15:43 2038

To pretty print the certificate:

$ pki-server cert-show ca_signing --pretty-print
  Cert ID: ca_signing
  Nickname: caSigningCert cert-pki-tomcat CA
  Token: Internal Key Storage Token
  Serial Number: 0x1
  Subject DN: CN=CA Signing Certificate,OU=pki-tomcat,O=EXAMPLE
  Issuer DN: CN=CA Signing Certificate,OU=pki-tomcat,O=EXAMPLE
  Not Valid Before: Tue Apr 03 23:15:43 2018
  Not Valid After: Sat Apr 03 23:15:43 2038

Certificate:
    Data:
        Version: 3 (0x2)
        Serial Number: 1 (0x1)
        Signature Algorithm: PKCS #1 SHA-256 With RSA Encryption
        Issuer: "CN=CA Signing Certificate,OU=pki-tomcat,O=EXAMPLE"
        Validity:
            Not Before: Tue Apr 03 23:15:43 2018
            Not After : Sat Apr 03 23:15:43 2038
        Subject: "CN=CA Signing Certificate,OU=pki-tomcat,O=EXAMPLE"
...

Generating System Certificate Request

To generate a new key pair in internal NSS token and an enrollment request:

$ pki-server cert-request \
    --subject "CN=CA Signing Certificate" \
    --ext /usr/share/pki/server/certs/ca_signing.conf \
    ca_signing

To store the key pair in HSM, specify --token <name> option.

The enrollment request will be stored in /etc/pki/<instance>/certs/<cert ID>.csr.

Availability: Since PKI 11.5.

Creating System Certificate

Creating Permanent Certificate

The pki-server cert-create can be used to create a system certificate using PKI server’s NSS database directly with RSNv3 serial numbers so it can be used before the CA subsystem is created or while the server is down.

Note: Do not use this command with legacy serial number generators (i.e. sequential or RSNv1).

To create a self-signed CA signing certificate:

$ pki-server cert-create \
    --ext /usr/share/pki/server/certs/ca_signing.conf \
    ca_signing

To issue a certificate signed by the CA signing certificate:

$ pki-server cert-create \
    --issuer ca_signing \
    --ext /usr/share/pki/server/certs/ca_signing.conf \
    sslserver

To sign with a key in HSM, specify --token <name> option.

Availability: Since PKI 11.5

Creating Temporary Certificate

The pki-server cert-create can be used to create a temporary SSL server certificate to restore the CA subsystem in case the existing certificate has already expired.

Note: The temporary certificate needs to be replaced with the permanent one once the CA subsystem is restored.

To create temporary certificate with the same serial number:

$ pki-server cert-create sslserver --temp

To create temporary certificate with specific serial number:

$ pki-server cert-create sslserver --temp --serial <serial>

Renewing Certificate

To renew permanent certificate:

$ pki-server cert-create <cert ID> --renew

By default the new certificate will be stored in /etc/pki/<instance>/certs/<cert ID>.crt. An optional --output <file> parameter can be added to specify a different output file.

Importing System Certificate

The following command can be used to import new certificate into the NSS database and update the copy of the certificate in the CS.cfg in all subsystems in the instance:

$ pki-server cert-import <cert ID>

By default it will import the certificate from /etc/pki/<instance>/certs/<cert ID>.crt. An optional --input <file> parameter can be used to specify a different input file.

Exporting System Certificate

To export a system certificate and key into a PKCS #12 file, execute the following command:

$ pki-server cert-export ca_signing --pkcs12-file ca_signing.p12 --pkcs12-password Secret.123

By default it will overwrite the output file. To append the certificate and key into an existing file specify the --append parameter.

To export a certificate into a PEM file, execute the following command:

$ pki-server cert-export ca_signing --cert-file ca_signing.crt
$ cat ca_signing.crt
