PWHISTORY_HELPER(8) Linux-PAM Manual PWHISTORY_HELPER(8)NAMEpwhistory_helper - Helper binary that transfers password hashes from
passwd or shadow to opasswd
SYNOPSISpwhistory_helper [...]
DESCRIPTIONpwhistory_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.
