1. What is the algorithm used to check the validity of a password?
```c
for (int i = 0; i < 4; i++) {
Seed[i] ^= password[i] ^ password[i + 4] ^ password[i + 8];
}
```
2. Can you break this password checker, i.e., implementing a generator of valid passwords?
You must send 16 different valid passwords by email to pascal+sre25@mod-p.ch before Mar. 3rd, 2025, 12h00 CET to validate this lab and get 5 points.
