NAME

       update-ca-certificates - update /etc/ssl/certs and certificates.crt

SYNOPSIS

       update-ca-certificates [options]

DESCRIPTION

       This manual page documents briefly the update-ca-certificates commands.
       This manual page was written for the Debian distribution.

       update-ca-certificates  is  a  program  that  updates   the   directory
       /etc/ssl/certs to hold SSL certificates and generates certificates.crt,
       a concatenated single-file list of certificates.

       It reads the file /etc/ca-certificates.conf. Each line gives a pathname
       of  a  CA  certificate  under /usr/share/ca-certificates that should be
       trusted.  Lines that begin with "#" are comment lines and thus ignored.
       Lines  that  begin with "!" are deselected, causing the deactivation of
       the CA certificate in question.

       Furthermore   all   certificates   found   below   /usr/local/share/ca-
       certificates are also included as implicitly trusted.

       Before   terminating,   update-ca-certificates   invokes  run-parts  on
       /etc/ca-certificates/update.d and  calls  each  hook  with  a  list  of
       certificates:  those  added  are  prefixed  with a +, those removed are
       prefixed with a -.
