I think it&#x27;s important to keep in mind that crypto is probably not on a Moore&#x27;s-Law-like track, so that the ciphers we&#x27;re relying on today will probably be trivial to break in 20 years. In fact, the things that make 80s-90s crypto breakable mostly aren&#x27;t algorithmic weaknesses but rather implementation flaws that weren&#x27;t well understood then but are now.<p>Quite a bit of 90s crypto remains unbreakable, because the data is at rest and will never be put back into a circumstance that exposes the weaknesses of its cryptosystem.
