Se o seu banco de dados for roubado, o invasor não terá as senhas em texto puro dos seus usuários, apenas os hashes.

Então, o invasor não poderá tentar usar essas senhas em outro sistema (como muitos usuários utilizam a mesma senha em vários lugares, isso seria perigoso).

## Instalar o `passlib`

O PassLib é uma excelente biblioteca Python para lidar com hashes de senhas.

Ele suporta muitos algoritmos de hashing seguros e utilitários para trabalhar com eles.
