Overview

This page describes the SSL configuration used by PKI. The SSL configuration is stored in /var/lib/pki/pki-tomcat/conf/server.xml as part of Tomcat JSS configuration.

Please note that in the current implementation the SSL settings are global, meaning it will affect PKI as a server and as a client (to other PKI servers or LDAP servers).

Default SSL Configuration

By default PKI will use the following SSL configuration.

General configuration

  • Strict ciphers: true
  • Client certificate authentication: want
  • server cert nickname file: /var/lib/pki/pki-tomcat/conf/serverCertNick.conf
  • password file: /var/lib/pki/pki-tomcat/conf/password.conf
  • password class: org.apache.tomcat.util.net.jss.PlainPasswordFile
  • NSS database: /var/lib/pki/pki-tomcat/alias

OCSP

  • OCSP: enabled
  • OCSP responder URL: http://$HOSTNAME:9080/ca/ocsp
  • OCSP responder certificate: ocspSigningCert cert-pki-ca
  • Cache size: 1000
  • Minimum cache entry duration: 60 seconds
  • Maximum cache entry duration: 120 seconds
  • Timeout: 10 seconds

SSL options

  • SSL2: disabled
  • SSL3: disabled
  • TLS: enabled

Note: If the SSL range ciphers parameters are defined, the SSL options parameters will be ignored.

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.
