Sempre que você passa exatamente o mesmo conteúdo (exatamente a mesma senha), você obtém exatamente a mesma sequência aleatória de caracteres.

Mas você não pode converter a sequência aleatória de caracteres de volta para a senha.

##### Porque usar hashing de senha

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

            boolean isBlankParentUrl = true;

            if (parentUrl != null) {
                for (int i = 0; i < parentUrl.length(); i++) {
                    if (!Character.isWhitespace(parentUrl.charAt(i))) {
                        isBlankParentUrl = false;
                    }
                }
            }

## Advanced description from docstring

You can limit the lines used from the docstring of a *path operation function* for OpenAPI.

Adding an `\f` (an escaped "form feed" character) causes **FastAPI** to truncate the output used for OpenAPI at this point.

It won't show up in the documentation, but other tools (such as Sphinx) will be able to use the rest.
