Not necessarily, but it depends.

Anything worth securing is using AES256 with GCM so this attack in particular has a computational complexity of 2^254 which is effectively infinity. The computational complexity of this problem is probably greater than the number of atoms in the universe.

Even using a quantum computer, the computational complexity using this attack would be equivalent to AES128 which is still a number you don't have the ability to even conceptualize.

If you want practical attacks against this type of thing, you should check out the BEAST, Lucky13, and CRIME attacks. Those are practical attacks against SSL and TLS.

Practical attacks are those you can actually execute in the wild. I think CRIME (a chosen plaintext attack that takes advantage of compression) only requires about 20,000 messages which is relatively small.

“Breaking” a crypto system usually means that you can decrypt a message faster than simply brute forcing the key. An example is DES which had a key space of 2^64, but only required 2^56 brute force attempts.

If I’m remembering my crypto correctly, quantum computers can break AES256 with 2^128 guesses, which is still effectively infinite from a practical perspective

The reality is that any good knife maker will make a BIFL knife, assuming whoever sharpens it knows what they’re doing.

I’d recommend that you check out the Tojiro DP gyuto. It’s a full 8” and can handle the majority of kitchen tasks, although I wouldn’t want to use it to dice garlic, for example.

It’s a solid, well-build knife in the gyuto style (so it’s a western chef knife style). It is stainless steel so maintenance is much easier. The blade is thin so it will cut very well. It’s also relatively hard so it will maintain its sharpness for awhile.

If you compare that to German chef knives, they are typically thicker and softer but not always.

I would strongly recommend you not go to r/chefknives because you’ll spend way too much. But stainless steel, western blade profile/handle, and a thin edge geometry make it one of the best knives you can get for $100
