Post-Quantum Cryptography Libraries
Post-quantum cryptography libraries, with the smallest sizes each one offers.
High safety requires a hybrid design, where a classical and a post-quantum signature must both verify. Without one, hash-based libraries rate Medium, and lattice-based and other libraries rate Low.
