# 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.
