Unless of course the algorithm that powers the crypto is discovered to be flawed and predictable.

The current algorithm is demonstrably the worst. ROT13 would be stronger.

ROT13 is too weak, use ROT26 it’s twice as strong.

This is what is actually happening right now in Estonia [1].

What's the solution? Make the card support at least 2 crypto algorithms and regenerate certificates, if a flaw in the main algorithm is found.
