Cryptography challenge (Rust)

You are given the output of one cryptography system and the code that generates the output, the problem is we do not have access to the 3 files the code uses!

The first one is the flag.txt and the others are two files that have random prime numbers P and Q!

Can you help us decrypting the output and get the flag?

This challenge requires you to have cryptography and coding skills. Any language is accepted to get the solution.
