 In case you're interested in running timing leakage tests using `dudect`, execute following

+> [!NOTE]
 > `dudect` is integrated into this library implementation of Kyber KEM to find any sort of timing leakages. It checks for constant-timeness of all *vital* functions including Fujisaki-Okamoto transform, used in decapsulation step. It doesn't check constant-timeness of function which samples public matrix `A`, because that fails the check anyway, due to use of uniform rejection sampling. As matrix `A` is public, it's not critical that it must be *strictly* constant-time.
 
 ```bash
 make dudect_test -j # Only on x86_64 machine
                     # Each executable is run for at max 3 mins.
 ```
