[2023 day 8] some guy on reddit manged to brute force part 2 in 57 seconds on a gpu
It's a good thing I killed my CPU attempt after 2 hours then!
I would have definitely died in that sandstorm!
12I don't know shit about stuff l7ke this, but it's interesting. What does this mean?
4An extremely watered-down version for a non-tech person: Let's say you want to hack an account's password. When you try all combinations of characters continuously like how they do in the movies, that is a type of brute-force algorithm. It is considered the least efficient form of problem-solving.
Now, instead of using a CPU, they're using a GPU. A GPU is also known as a display driver. It calculates and renders graphical stuff. That's not the CPU's job - it is simply not good at it, for a bunch of reasons.
Now, a CPU is very fast, but can calculate fewer results. However, a GPU is slow, but can calculate in bulk. This is for the same reason why some people use GPU for mining crypto coin (they have been superseded by FGPA and ASIC).
Calculating on a GPU is not as straight forward as using a CPU. Now, I did not read the post clearly, but this Reddit guy apparently used GLSL to calculate stuff? I am not really sure about the specifics of how, and why was this used. Last I remember using GLSL, you can't simply use that to print log on the screen. Maybe they're using OpenGL? Maybe Vulkan?
