1. NIST is taking a long time to finalize post-quantum-computing cryptography standards.
2. There has been a significant increase in quantum technology and understanding since 2016.
3. Only four algorithms have been finalized so far, but more candidates are under consideration.
4. Developing quantum-resistant algorithms is important, but it takes time.
5. It usually takes several years for vendors to develop and validate products based on new standards.
6. Cryptography combines mathematics and complexity, and post-quantum algorithms are more complicated and less understood.
7. More cryptanalytic results and algorithm vulnerabilities are expected.
8. Cryptographic agility is important to easily swap in new algorithms when required.
9. Expect that any new standard from NIST will eventually become vulnerable to advances in mathematics.
