Only PQ hash functions are PQ FWIU. Other cryptographic hash functions are not NIST PQ standardization finalists; I don't think any were even submitted with "just double the key/hash size for the foreseeable future" as a parameter as is suggested here. https://news.ycombinator.com/item?id=25009925 https://news.ycombinator.com/item?id=25009925 NIST Post-Quantum Cryptography Standardization > Round 3 > Selected Algorithms 2022 > Hash based > SPHINCS+: https://en.wikipedia.org/wiki/NIST_Post-Quantum_Cryptography_Standardization#Finalists https://en.wikipedia.org/wiki/NIST_Post-Quantum_Cryptography... SPHINCS+ is a hash based PQ Post Quantum (quantum resistant) cryptographic signature algorithm. SPHINCS+: https://github.com/sphincs/sphincsplus https://github.com/sphincs/sphincsplus
