update-ca-certificates [options]

       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/local/share/ca-certificates   are   also  included  as  implicitly

       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 -.

       A summary of options is included below.
