[$] NIST finalizes post-quantum encryption standards

On August 13, the US National Institute of Standards and Technology (NIST)published the final form of its new post-quantum cryptographic standards. Onekey-exchange mechanism and two digital-signature schemes are now officiallysanctioned by the institute. Adopting the new standards should be fairlypainless for most developers, but the overhead added by the schemes could posechallenges for some applications.
