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 -.
