gnupgp post quantum keys
Hi-
Once they make a standard for one of the algorithms being considered for post quantum cryptography, will we be able to use the same clients like kleopatra, SSH, etc. to use like a lattice key instead of RSA? I just read on zdnet that one of the questions surrounding verizon's quantum VPN was the delivering keys (securely) to endpoints. Won't the programs I just mentioned run into the same issue? thanks, roboloki |
Hi -
I just recalled that like in ssh the private key never goes to the to other host. I don't know what the guy at the zdnet article is talking about. It says VPN on google is asymmetric. Quote:

Then, for each application the corresponding IETF standards need to be updated to allow the use of whatever PQC algorithms are available. In the case of OpenPGP for example, the working group is already aware of that, but there’s nothing much they can do for now until the first step has been completed. Then, it will be up to the developers to actually implement the thing. Quote:
Of course the problem of authenticating the public key of the peer – to be sure that you’re talking to who you think you are talking to – remains. As far as I know, this is nowhere near solved by post-quantum cryptography (which is not the silver bullet that some people sometimes believe it is). Likewise, PQC will also not solve the problem known as "Adi Shamir’s Law", which states that "cryptography is bypassed, not penetrated". |
