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  certifi-
       cates: those added are prefixed with a +, those removed are prefixed with a -.
