.SH "DESCRIPTION"
This function adds the trusted CAs in order to verify client or
server certificates. In case of a client this is not required to
be called if the certificates are not verified using
\fBgnutls_certificate_verify_peers2()\fP.  This function may be called
multiple times.

In case of a server the names of the CAs set here will be sent to
the client if a certificate request is sent. This can be disabled
using \fBgnutls_certificate_send_x509_rdn_sequence()\fP.

This function can also accept URLs. In that case it
will import all certificates that are marked as trusted. Note
that the supported URLs are the ones indicated by \fBgnutls_url_is_supported()\fP.
