In FIPS mode, certain HSMs may require enabling certain SSL ciphers in order to work with PKI CLI and Firefox 34 or older (newer Firefox will not work).
 
 
 
For Thales HSM, enable the following SSL range ciphers for '''RSA ciphers''':
 
* TLS_DHE_RSA_WITH_AES_128_CBC_SHA
 
* TLS_DHE_RSA_WITH_AES_256_CBC_SHA

* TLS_RSA_WITH_AES_128_CBC_SHA256
 
* TLS_RSA_WITH_AES_256_CBC_SHA256
 
* TLS_RSA_WITH_AES_128_CBC_SHA (may need to remain enabled in order to talk to the LDAP server during pkispawn installation/configuration)
 
* TLS_RSA_WITH_AES_256_CBC_SHA (may need to remain enabled in order to talk to the LDAP server during pkispawn installation/configuration)
 
 
 
Disable everything else in SSL range ciphers.

== Procedure to create an RSA Server in FIPS mode ==
 
 
 
In systems prior to Fedora 27 (pki-core-10.5.5-1), in order to configure an RSA server, it was necessary to run pkispawn in two separate steps (installation and configuration).
 
 
 
With the completion of https://pagure.io/dogtagpki/issue/2855 which altered FIPS ciphers to be the default cipher suite,
 
pkispawn installation/configuration can be run in a single pass, and the same default RSA cipher suite is utilized, regardless of whether or not FIPS has been enabled or disabled.
 
 
 
For systems running Fedora 27 (pki-core-10.5.5-1) or later, the following sample procedure may be used to create a Dogtag CA RSA Server in FIPS mode using a software token:
 
 
 
    Enabling FIPS status:
 
   
 
        (1) dnf install dracut-fips
 
        (2) reboot
 
        (3) press 'e' on the grub config menu to 'edit' the selected kernel
 
        (4) add "fips=1" to the end of the boot line, or when multiple
 
            disks/partitions are involved (e. g. - "fips=1 boot=/dev/sda1")
 
        (5) Ctrl-x to boot with fips mode enabled
 
   
 
    # sysctl crypto.fips_enabled
 
    crypto.fips_enabled = 1
 
   
 
    # script -c "pkispawn -s CA -f /root/pki/ca.cfg -vvv" typescript.ca-rsa-fips
 
   
 
        where 'ca.cfg' contains:
 
   
 
            [DEFAULT]
 
            pki_admin_password=<password>
 
            pki_client_pkcs12_password=<password>

FIPS SSL Configuration

See FIPS SSL Configuration.

Customizing SSL Configuration

During Installation

During installation the installer will use the default SSL configuration. Under certain circumstances (e.g. in FIPS mode) the default SSL configuration may not work. To customize the SSL configuration during installation use the Two-Step Installation:

  • Prepare a normal deployment configuration.
  • Add pki_skip_configuration=True to the configuration and run pkispawn.
  • Customize the SSL parameters as needed in /var/lib/pki/pki-tomcat/conf/server.xml
  • Replace pki_skip_configuration=True with pki_skip_installation=True and run pkispawn again.

After Installation

After installation the SSL settings can be customized directly in /var/lib/pki/pki-tomcat/conf/server.xml.
