Interesting background info, including recommended minimum key sizes during the

I find it interesting that symmetric ciphers like 256 bit AES are
probably quantum resistant[0], while all currently used public key
systems can be easily broken with quantum computers (because they're
based on integer factorization and discrete logarithms). So any traffic
recorded today[1] that is using Diffie-Hellman key exchange will be
easily broken in the not so far future. This has made me appreciate
pre-shared key systems again.
