This document describes the process to install PKI CA with a CA certificate generated by OpenSSL.
Generate a new key with the following command:
$ openssl genrsa -out ca.key 2048 Generating RSA private key, 2048 bit long modulus .......+++ ....................................................+++ e is 65537 (0x10001)
Generate a CA certificate request with the key with the following command:
$ openssl req -key ca.key -nodes -new -out ca.csr -subj "/CN=CA Certificate/O=Example" -days 365
Verify the CA certificate request:
$ openssl req -text -noout -in ca.csr

Generate the CA certificate using the existing key with the following command:
$ openssl req -x509 -new -key ca.key -nodes -out ca.crt -subj "/CN=CA Certificate/O=Example" -days 365 -set_serial 1
Note: If you use a different serial number, specify the same value in hex in pki_serial_number_range_start deployment parameter (see Serial Number Ranges).
Verify the CA certificate:
$ openssl x509 -text -noout -in ca.crt

Import the CA certificate and key into a PKCS #12 file with the following command:
$ echo Secret.123 > password.txt $ openssl pkcs12 -export -in ca.crt -inkey ca.key -out ca.p12 -name "CA Certificate" -passout file:password.txt
Initialize an NSS database for the pki utility:
$ pki -c Secret.123 client-init
Set the trust flags for the CA certificate:
$ pki pkcs12-cert-mod --pkcs12-file ca.p12 "CA Certificate" --pkcs12-password-file password.txt --trust-flags "CTu,Cu,Cu"
Note: make sure there are no spaces in the trust flags.
Verify with the following commands:
$ pki pkcs12-cert-find --pkcs12-file ca.p12 --pkcs12-password-file password.txt --------------- 1 entries found --------------- Certificate ID: 9311084d08b37d12e856b904b7e52eb3b1cece4a Serial Number: 0xe3f2b350edcd875c Nickname: CA Certificate Subject DN: O=Example,CN=CA Certificate Issuer DN: O=Example,CN=CA Certificate Trust Flags: CTu,Cu,Cu Has Key: true $ pki pkcs12-key-find --pkcs12-file ca.p12 --pkcs12-password-file password.txt --------------- 1 entries found --------------- Key ID: 9311084d08b37d12e856b904b7e52eb3b1cece4a Subject DN: CA Certificate Algorithm: RSA
Prepare a deployment configuration file:
[CA] pki_admin_email=caadmin@example.com pki_admin_name=caadmin pki_admin_nickname=caadmin pki_admin_password=Secret.123 pki_admin_uid=caadmin pki_client_database_password=Secret.123 pki_client_database_purge=False pki_client_pkcs12_password=Secret.123 pki_ds_base_dn=dc=ca,dc=pki,dc=example,dc=com pki_ds_database=ca pki_ds_password=Secret.123 pki_security_domain_name=EXAMPLE pki_token_password=Secret.123 pki_existing=True pki_ca_signing_nickname=CA Certificate pki_ca_signing_csr_path=/tmp/ca.csr pki_pkcs12_path=/tmp/ca.p12 pki_pkcs12_password=Secret.123
Start the installation with the following command:
$ pkispawn -v -f ca.cfg -s CA
