1 2 3 4 5 6 7 8 9 10 11 12 13 | .IP "\fB\-\-peer\-ca\-cert=\fIpeer-cacert.pem\fR"
Specifies a PEM file that contains one or more additional certificates
to send to SSL peers. \fIpeer-cacert.pem\fR should be the CA
certificate used to sign \fB\*(PN\fR's own certificate, that is, the
certificate specified on \fB\-c\fR or \fB\-\-certificate\fR. If
\fB\*(PN\fR's certificate is self-signed, then \fB\-\-certificate\fR
and \fB\-\-peer\-ca\-cert\fR should specify the same file.
.IP
This option is not useful in normal operation, because the SSL peer
must already have the CA certificate for the peer to have any
confidence in \fB\*(PN\fR's identity. However, this offers a way for
a new installation to bootstrap the CA certificate on its first SSL
connection.
