Well, first, why do we believe the aliens? Assuming we do and
ignoring the first two, if they offer evidence for the statement
that P = NP, then that evidence may offer useful hints for
developing attacks. The same comment applies if we develop that
evidence without space aliens.
However, I don't expect to wake up one day with no warning to
find I can download a RSA/ECC breaker. (Unless the math is
developed in NSA/GCHQ/KGB/etc. and the break is developed in
secret.) If the math is public, it will take some time to
develop breaks. However, that time may be shorter than the eons
it takes to update SSL/TLS. (Look at the number of sites still
vulnerable to Heartbeat.)
