Quantum Safe Password Manager

Most password managers rely on cryptography that a sufficiently powerful quantum computer could break. This project builds credential handling on the Kyber algorithm, a post-quantum key encapsulation mechanism, so stored secrets stay safe even against that future.

The design assumes an adversary who can record encrypted vaults today and decrypt them years later with quantum hardware, the harvest-now, decrypt-later attack. Defending against that means post-quantum primitives at the key-exchange layer, not just longer passwords.

Encryption workflows and key management are automated in Python, wrapping Kyber key encapsulation around vault operations. The whole application is containerised with Docker, making deployment portable and keeping the crypto environment pinned and reproducible.

The result is a working, portable, quantum-resistant credential manager, and a deep dive into what it takes to design cryptographically robust systems: understanding the primitives, not just importing them.
