nss_pcache - Helper program used to store token password pins
nss_pcache <semid> <fips on/off> <directory> [prefix]
A helper program used by the Apache httpd
mod_nss plug-in to store the
NSS PKCS #11 token password pins between restarts of Apache.
Whenever an Apache httpd
process configured to use the mod_nss plug-in is
started, this program will be automatically invoked via reference to the
mod_nss configuration file stored under /etc/httpd/conf.d/nss.conf
which contains the following default entry:
- # Pass Phrase Helper:
# This helper program stores the token password pins between
# restarts of Apache.
# NOTE: Located at '/usr/sbin/nss_pcache' prior
# to 'mod_nss-1.0.8-22'.
- The semaphore which corresponds to the mod_nss plug-in
registered with the Apache httpd process during startup.
- <fips on/off>
- Specifies whether FIPS mode should be enabled, on,
or disabled, off. By default, FIPS mode is disabled, and no
variable is specified in /etc/httpd/conf.d/nss.conf. To enable FIPS
mode, establish password access for the specified NSS security databases,
and specify the following variable in
- Specifies the destination directory of the NSS databases
that will be associated with this executable specified by the following
entry in /etc/httpd/conf.d/nss.conf:
||# Server Certificate Database:
||# The NSS security database directory that holds the
||# certificates and keys. The database consists
||# of 3 files: cert8.db, key3.db and secmod.db.
||# Provide the directory that these files exist.
- Optional prefix to attach prior to the names of the NSS
certificate and key databases contained in the directory referenced by the
previous argument and specified by the following entry in
/etc/httpd/conf.d/nss.conf (must be uncommented in order to be
||# Database Prefix:
||# In order to be able to store multiple NSS databases
||# in one directory they need unique names. This option
||# sets the database prefix used for cert8.db and key3.db.
