Or if the OP is already redirecting / piping stdin in the cron job command line, something like this:
(cat input.txt; sleep 10) | openssl s_client ...
so that stdin remains open for a while after the actual input is exhausted. Maybe use that in conjunction with -ign_eof (shouldn't hurt, assuming the server closes its end of the connection when it's done).
