The conventional answer to not doing anything is that you are now doing
cryptography.  So you have to explain to yourself why you think you can
do better than the people who spent their lives on this.  Are you that good?

In practice, you are far better off using their work as described in the
manual.  And spending the spare time on writing better software.

Given that the leading software break is still due to buffer overflows,
and nobody's ever cracked a big-name crypto algorithm in living memory,
you're probably better off focussing on the known roadkill not the
zombies in hollywood movies.
