+# How to:
+# First, `make yourhost.cnf` which creates a openssl config file.
+# Then edit this file and fill in the details you want it to have,
+# and add or change hosts and components it should cover.
+# Then `make yourhost.key` to create your private key, you can
+# include keysize=number to change the size of the key.
+# Then you can either `make yourhost.csr` to generate a certificate
+# signing request that you can submit to a CA, or `make yourhost.cert`
+# to generate a self signed certificate.
+
+# To request a cert
+%.csr: %.cnf %.key
+	openssl req -new -key $(lastword $^) -out $@ -utf8 -config $(firstword $^)
+
+# Self signed
+%.cert: %.cnf %.key
+	openssl req -new -x509 -nodes -key $(lastword $^) -days 365 \
+		-sha1 -out $@ -utf8 -config $(firstword $^)
+
+%.cnf:
+	sed 's,example\.com,$*,g' openssl.cnf > $@
+
+%.key:
+	openssl genrsa $(keysize) > $@
+	@chmod 400 -c $@
