--bootstrap-ca-cert=
cacert.pem
When cacert.pem exists, this option has the same effect
as -C
or --ca-cert
. If it does not exist,
then the executable will attempt to obtain the CA certificate from the
SSL peer on its first SSL connection and save it to the named PEM
file. If it is successful, it will immediately drop the connection
and reconnect, and from then on all SSL connections must be
authenticated by a certificate signed by the CA certificate thus
obtained.
This option exposes the SSL connection to a man-in-the-middle attack obtaining the initial CA certificate, but it may be useful for bootstrapping.
This option is only useful if the SSL peer sends its CA certificate as part of the SSL certificate chain. The SSL protocol does not require the server to send the CA certificate.
This option is mutually exclusive with -C
and
--ca-cert
.
