In the movie "Summer Wars," there is a scene where the main character Kenji Koiso (小磯健二) receives a mysterious sequence of numbers, which he solves in one night, resulting in a serious problem.
The cipher that he used was RSA cipher, and he was able to factorize a huge number of digits in one night.
As an aside. In Japan, during reruns of Summer Wars, everyone yells Yes, please! (よろしくお願いしまぁぁぁすっ!!).
This program challenges you to solve RSA cryptography by using wasm-bindgen and launching WebAssembry created by Rust on your browser.
Therefore, there is no need for a server for the calculation. It would be a shame if everyone had to run such a heavy script.
