Most modern symmetric-key algorithms appear to be resistant to the threat of [[post-quantum cryptography]].<ref name="djb-intro">{{cite book |author=Daniel J.

By contrast, it would still take a quantum computer the same amount of time to decode a 256 bit AES cipher as it would a conventional computer to decode a 128 bit AES cipher.<ref>{{Cite web |last=Wood |first=Lamont |date=2011-03-21 |title=The Clock Is Ticking for Encryption |url=https://www.computerworld.com/article/2550008/the-clock-is-ticking-for-encryption.html |access-date=2022-12-05 |website=Computerworld |language=en}}</ref> For this reason, AES-256 is believed to be "quantum resistant".<ref>{{Cite web |last=O'Shea |first=Dan |date=2022-04-29 |title=AES-256 joins the quantum resistance |url=https://www.fierceelectronics.com/electronics/aes-256-joins-quantum-resistance |access-date=2022-12-05 |website=Fierce Electronics |language=en}}</ref>
