## Hashing de senhas

"Hashing" significa converter algum conteúdo (uma senha neste caso) em uma sequência de bytes (apenas uma string) que parece um monte de caracteres sem sentido.

Sempre que você passar exatamente o mesmo conteúdo (exatamente a mesma senha), você obterá exatamente o mesmo resultado.

Mas não é possível converter os caracteres sem sentido de volta para a senha original.
