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.

Encrypted “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.
