Cryptography today is based on veteran public key systems:

– Diffie-Hellman (1976).
– RSA (1977)
– Elliptical Curves (1985).

Elliptic curve cryptography is the most advanced cryptographic system available. Elliptic curves are rapidly replacing RSA as the gold standard for public key cryptography.

But all of them are more than 30 years old, and in fact the Elliptical Curves one has started to be implanted in a massive way now. Over time, we should see these systems in decline.

This in the case of symmetric cryptography and hash functions should theoretically be revised (at least duplicated) to prevent the effect of quantum computers. Although the time frame for this to happen is probably much longer than what is being published.
