A cryptography engineer calls for an urgent rollout of quantum-resistant cryptography, saying the risk of inaction is now unacceptable, after Google's warning
My position on the urgency of rolling out quantum-resistant cryptography has changed compared to just a few months ago.

I think this is a good precautionary analysis but I'd bet huge amounts of money against a relevant quantum computer by 2029 or even 2035. [embedded post]

Hopefully the PQC algorithms we have are strong even though they aren't battle tested and commercial vendors have been adding them to products for a few years; what we need in organisations is for folks to turn them on and do the relevant cert management. Not sure open source is…

Probably since he's the one leading the awareness campaign on QC. See words.filippo.io/crqc-timeline/
