UPDATE-CA-CERTIFICATES(8)   System Manager's Manual  UPDATE-CA-CERTIFICATES(8)

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

SYNOPSIS
       update-ca-certificates [options]

DESCRIPTION
       This manual page documents briefly the update-ca-certificates command.

       update-ca-certificates   is   a  program  that  updates  the  directory
       /etc/ssl/certs to  hold  SSL  certificates  and  generates  ca-certifi-
       cates.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. Certificates must have a .crt extension
       in order to be included by update-ca-certificates.

       Furthermore all certificates with a .crt extension found below /usr/lo-
       cal/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  cer-
       tificates:  those  added  are prefixed with a +, those removed are pre-
       fixed with a -.
