NIST wants to ban ECDSA in 2035. It is tight.

HTTPS, messengers, cryptocurrencies and everyone else will need to move to new algorithms. Not all functionality is currently feasible in pq setting.

Here’s an excerpt from noble-post-quantum on speed & key size in JS implementations.

Thanks for sharing this information about NIST's plan to ban ECDSA in 2035. It's definitely something that developers and users of HTTPS, messengers, and cryptocurrencies will need to keep in mind as they prepare for the future. It's interesting to consider the challenges that come with transitioning to new algorithms, especially when not all functionality is currently feasible in pq setting. I appreciate the excerpt you shared on speed and key size in JS implementations – it's helpful to see this kind of analysis. Take care!
