PWHISTORY_HELPER(8)            Linux-PAM Manual            PWHISTORY_HELPER(8)

NAME
       pwhistory_helper - Helper binary that transfers password hashes from
       passwd or shadow to opasswd
SYNOPSIS
       pwhistory_helper [...]
DESCRIPTION
       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.
