Older versions of OpenSSL exported (AFAIK) a usable version of
arc4random_buf() that could have helped here; it seems to still be
there in libressl[1] which is mostly API compatible and might be worth
looking into IMHO even if as you pointed out will need an
implementation similar to what OpenSSL does internally.
