@unnumbered Restricted CAs

You can restrict what hosts are allowed to be served by the specified
CA. For example you want to limit CA with SPKI's SHA256 hash of
@code{9215d9eeddeb403b0ffebb228cfc13104da825117d3640a0dfbfc0c08a012124}

@example
$ tee fifos/add-restricted <contrib/restricted.txt
9215d9eeddeb403b0ffebb228cfc13104da825117d3640a0dfbfc0c08a012124 stargrave.org
