PKI 10.5 pkispawn ECC Profile Workaround
Note: This workaround is no longer needed starting 10.6 due to the fix from Ticket 3077 - Address ECC profile overrides
Currently, the man page for pkispawn
has a section entitled Installing a root CA using ECC, and the documented values will produce incorrect ECC certificates for the Admin, Server, and and Subsystem certificates because the RSA profiles are used to produce them.
Additionally, in the /etc/pki/default.cfg
file, the following section exists under the [CA]
section:
# Paths # These are used in the processing of pkispawn and are not supposed # to be overwritten by user configuration files. # pki_source_emails=/usr/share/pki/ca/emails pki_source_flatfile_txt=%(pki_source_conf_path)s/flatfile.txt pki_source_profiles=/usr/share/pki/ca/profiles pki_source_proxy_conf=%(pki_source_conf_path)s/proxy.conf pki_source_registry_cfg=%(pki_source_conf_path)s/registry.cfg pki_source_admincert_profile=%(pki_source_conf_path)s/adminCert.profile pki_source_caauditsigningcert_profile=%(pki_source_conf_path)s/caAuditSigningCert.profile pki_source_cacert_profile=%(pki_source_conf_path)s/caCert.profile pki_source_caocspcert_profile=%(pki_source_conf_path)s/caOCSPCert.profile pki_source_servercert_profile=%(pki_source_conf_path)s/serverCert.profile pki_source_subsystemcert_profile=%(pki_source_conf_path)s/subsystemCert.profile pki_subsystem_emails_path=%(pki_subsystem_path)s/emails pki_subsystem_profiles_path=%(pki_subsystem_path)s/profiles
which states that the following three name=value pairs should not be overwritten by a user configuration file:
pki_source_admincert_profile=%(pki_source_conf_path)s/adminCert.profile pki_source_servercert_profile=%(pki_source_conf_path)s/serverCert.profile pki_source_subsystemcert_profile=%(pki_source_conf_path)s/subsystemCert.profile
It turns out that the statement in the /etc/pki/default.cfg
is not entirely correct, as a work-around exists for this problem by explicitly overriding these three name=value pairs in the user configuration file.
For example, when something like the following is used as a user configuration override file:
[DEFAULT] pki_admin_password=<password> pki_client_pkcs12_password=<password> pki_ds_password=<password> # Override default RSA Admin parameters with ECC parameters pki_admin_key_algorithm=SHA256withEC pki_admin_key_size=nistp256 pki_admin_key_type=ecc # Override default RSA SSL Server parameters with ECC parameters pki_sslserver_key_algorithm=SHA256withEC pki_sslserver_key_size=nistp256 pki_sslserver_key_type=ecc # Override default RSA Subsystem parameters with ECC parameters pki_subsystem_key_algorithm=SHA256withEC pki_subsystem_key_size=nistp256 pki_subsystem_key_type=ecc [CA] # Override default RSA CA Signing parameters with ECC parameters pki_ca_signing_key_algorithm=SHA256withEC pki_ca_signing_key_size=nistp256 pki_ca_signing_key_type=ecc pki_ca_signing_signing_algorithm=SHA256withEC # Override default RSA CA OCSP Signing parameters with ECC parameters pki_ocsp_signing_key_algorithm=SHA256withEC pki_ocsp_signing_key_size=nistp256 pki_ocsp_signing_key_type=ecc pki_ocsp_signing_signing_algorithm=SHA256withEC # Attempt to override RSA profiles with ECC profiles pki_source_admincert_profile=/usr/share/pki/ca/conf/ECadminCert.profile pki_source_servercert_profile=/usr/share/pki/ca/conf/ECserverCert.profile pki_source_subsystemcert_profile=/usr/share/pki/ca/conf/ECsubsystemCert.profile
which will result in correct ECC certificates for Admin, Server, and Subsystem with the following anomolous behavior:
The PKI ECC system profiles will be re-named to their RSA equivalent names in the PKI instance location:
-
/usr/share/pki/ca/conf/ECadminCert.profile
⇒/var/lib/pki/<instance>/conf/ca/adminCert.profile
-
/usr/share/pki/ca/conf/ECserverCert.profile
⇒/var/lib/pki/<instance>/conf/ca/serverCert.profile
-
/usr/share/pki/ca/conf/ECsubsystemCert.profile
⇒/var/lib/pki/<instance>/conf/ca/subsystemCert.profile
Both the overriding names as well as the instance destination names will appear in the log files leading to potential confusion on whether or not the proper ECC profiles were utilized rather than their RSA profile counterparts.
The following ticket has been created to eliminate the need for the workaround:
