For anyone who's fresh to cyber security, the fundamental axiom of it is that anything can be cracked, only a matter of computations (time*resource). Just as the dose makes the poison (sola dosis facit venenum).

Suppose you have a secret, that is RSA-encrypted, we might be looking at three hundred trillion years according to Wikipedia with the kind of computer we have now. Obviously that secrecy would have lost its value then, and the resource it requires to crack the secret would worth more than the secret itself. Even with quantum computing, we are still looking at 20+ years, which is still enough for most of the secrets, you got plenty time to change it, or after it lost its value. So we say that's secure enough.
