The National Institute of Standards and Technology has finally published the world’s first three official post-quantum cryptographic algorithms, tools designed to protect key systems against future quantum computers powerful enough to crack any code generated by a modern computer.
At the same time, everyone has already downloaded every encrypted archive in the world and will decrypt them first thing quantum computing becomes available, so all the data up until now are public data.
3Encrypted "archives" like zip or similar will not be crackable by quantum computers. They use (if strongly encrypted) a well known stream cypher like AES. Those are not severely impacted by QC.
Only asymmetric crypto like RSA or ECDSA (elliptic curve) are easily cracked by a powerfull QC. These are used in communications like https.
Internet cummunication is fucked with qc. Stuff encrypted with a strong password is not.
