Re: Quantum computing and decryption
"Doesn't that mean that we could switch to those methods and quantum computers would stop being such a bogeyman for encryption?"
Yes, quantum secure algorithms have been (and continue to be) developed - there are various calls out by NIST on the subject which are readily accessible.
This would mean that now (or in the near future) would be a good time to snatch encrypted data - before such algorithms come into common use; that data might then be decryptable by future quantum computers.
Whether the data retains its value in the future points to one of the considerations that should be made when deciding data encryption choices: do you need to secure data for a few minutes, hours, days, months, years, or forever. For example, a short-lived 2FA code should have no value after a few minutes, whereas a collection of identificatiion data of the people that have assisted you in a hostile region of the world ought to be protected for many many years.
