"And even if you need that peace of mind, let me tell you a secret: no practical attacks on AES, SHA-3 or other solid ciphers and hashes are known in the “unclassified” literature, either. Are you going to stop using those, as well? Of course not!"

- Tomte 10y ago"Practical attacks". "Quantum computers". I fail to see how these might be related.
- joelbondurant 10y agoIf you're working on storing cat videos on your personal website, I completely agree.
- Tomte 10y agoNo, I'm storing urandom articles on my personal website. Cat videos are much too popular and a lot bigger, and since I'm paying for traffic... [0] ;-) [0] regular traffic: ~30 MB/day, today (projected): ~3.5 GB
- adrianN 10y agoGrover's algorithm, even assuming that we have hardware that can efficiently implement it, improves the runtime of a brute force attack on AES-256 from 10^49 * age of the universe to 10^10 * age of the universe. Hardly practical. All symmetric ciphers and all hashes are quantum-proof. Key exchange might become problematic, but that is a different problem
