It's certainly not the cause of this hack, but nobody should be using asymmetric encryption to protect their own stuff. It should only be used for communication

It's certainly not the cause of this hack, but nobody should be using asymmetric encryption to protect their own stuff. It should only be used for communication with another party. Quantum computing will eventually be a thing.
So use symmetric encryption whenever it's at all possible.
- eastbound 4y agoIs symmetric encryption safer? Why so? As well, if asymetric encryption is ever broken, then nothing is safe on the internet.
- dtech 4y agoFrom quantum computing attacks it is safer, specifically because there is a fast quantum algorithm for prime factoring [1]. However, including working quantum computers in your threat profile is ridiculous for things like this at the moment.

- MuffinFlavored 4y ago> asymmetric encryption PGP? RSA? Can you elaborate please? > symmetric encryption AES? Is this what you mean? What's the best way to do AES these days? AES-256-CBC? Is there "symmetric encryption" that is public key/private key? I know AES you just need IV + key and you're "good to go"?
- torben-friis 4y agoI think he’s just implying that since asymmetric depends on the reverse operation being slow, there will eventually be a system fast enough or a non slow algorithm for the operation. A bit far fetched IMO if the threat model depends on quantum computing but I have no idea about the subject so…
