Kısacası, `stanleyjobsox` ile `stanleyjobson`’u karşılaştırmak için geçen süre, `johndoe` ile `stanleyjobson`’u karşılaştırmak için geçen süreyle aynı olur. Şifre için de aynı şekilde.

Bu sayede uygulama kodunuzda `secrets.compare_digest()` kullanarak bu güvenlik saldırıları ailesine karşı güvenli olursunuz.
