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. .PP Furthermore all certificates with a .crt extension found below /usr/local/share/ca-certificates are also included as implicitly trusted. .PP Before terminating, \fBupdate-ca-certificates\fP invokes \fBrun-parts\fP on /etc/ca-certificates/update.d. .SH FILES .TP .I /etc/ca-certificates.conf A configuration file. .TP .I /etc/ssl/certs/ca-certificates.crt A single-file version of CA certificates. This holds all CA certificates that you activated in /etc/ca-certificates.conf. .TP .I /usr/share/ca-certificates Directory of CA certificates. .TP .I /usr/local/share/ca-certificates Directory of local CA certificates (with .crt extension). .SH AUTHOR This manual page was written by Fumitoshi UKAI , for the Debian project (but may be used by others).
