In college I was told over and over that SECURITY BY OBSCURITY IS NOT ACTUALLY SECURITY. So using thoroughly tested and examined security techniques from open source software is the gold standard.
There are known secure algorithms that cannot be cracked by modern computers. So, no reason to try and reinvent the wheel and just hope your way is better despite decades of refinement and research into modern open algorithms.
