PWHISTORY_HELPER(8) Linux-PAM Manual PWHISTORY_HELPER(8)
pwhistory_helper - Helper binary that transfers password hashes
from passwd or shadow to opasswd
pwhistory_helper [...]
pwhistory_helper is a helper program for the pam_pwhistory module
that transfers password hashes from passwd or shadow file to the
opasswd file and checks a password supplied by user against the
existing hashes in the opasswd file.
The purpose of the helper is to enable tighter confinement of
login and password changing services. The helper is thus called
only when SELinux is enabled on the system.
The interface of the helper - command line options, and
input/output data format are internal to the pam_pwhistory module
and it should not be called directly from applications.
pam_pwhistory(8)
Written by Tomas Mraz based on the code originally in
pam_pwhistory and pam_unix modules.
