My dude, rsa is fine. This article is talking about a company called rsa, not rsa encryption. I have never heard of doubt about rsa's security, given enough size. The main issue with raa is that it needs to be thousands of bits in size due to not being very efficient. And of course it is not post quantum.

> I have never heard of doubt about rsa’s security With all due respect, you must have missed it somehow, there's a lot of information about it online. [Here's a link to Cloudflare's blog about the topic](https://blog.cloudflare.com/how-the-nsa-may-have-put-a-backdoor-in-rsas-cryptography-a-technical-primer/). Now, to what extent this is worth worrying about, absolutely is up for discussion, and as you said RSA itself is not going to really matter either way in a post-quantum world. My comment wasn't really meant to start a serious discussion on cryptoanalysis, I'm not a cryptographic expert by any means, but there are serious concerns about NSA cracking or backdooring various popular encryption algorithms and they've been circulating the Internet for decades at this point!
