update-ca-certificates - update /etc/ssl/certs and certificates.crt
This manual page documents briefly the
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 -.
