update-ca-certificates - update /etc/ssl/certs and certificates.crt
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 certificates: those added are prefixed with a +, those removed are prefixed with a -.
A summary of options is included below.
-h, --help Show summary of options. -v, --verbose Be verbose. Output c_rehash. -f, --fresh Fresh updates. Remove symlinks in /etc/ssl/certs directory.
/etc/ca-certificates.conf A configuration file. /etc/ssl/certs/ca-certificates.crt A single-file version of CA certificates. This hold all CA certificates that you activated in /etc/ca-certificates.conf. /usr/share/ca-certificates Directory of CA certificates. /usr/local/share/ca-certificates Directory of local CA certificates (with .crt extension).
