Are you concerned about 'harvest now, decrypt later' attacks?

The term refers to the sort of obvious, especially in hindsight, idea that public or leaked encrypted data that today is impractical to crack can be 'harvested', and decrypted whenever the harvester has quantum capabilities; even if the original data source is updated to use a quantum cryptography/a quantum-resistant algorithm in the meantime.

(Or I suppose it applies equally well to any contemporarily sufficient encryption, (I'm sure there's been post-war decryption of ciphertexts collected but not cracked during, for example) it needn't be about quantum specifically, but that's where we are and what the term seems to have been coined for.)
