+
+The first component should be a CN, and should contain the name of the
+https server, this is because of compatiblity with older software. The
+more modern way to do this is to use SubjectAltName with dNSName set,
+these can be added with the --hostname switch. When using jabber
+certificate its quite common to have serveral name since the many
+clients disagree on what the name in the certificate should be and what
+the hostname should be.
+
+This example show creating a https server certificate for the host
+www.test.h5l.se that also serves www2.test.h5l.se for compatiblity
+reasons.

+@example
+hxtool issue-certificate \
+    --ca-certificate=FILE:ca.pem \
